Megaphones are handheld loudspeakers with cone-shaped devices that are designed to amplify and direct your voice. They enable you to be clearly heard by an audience and to effectively project your voice over a long distance.

Our bullhorn megaphones are battery-powered and feature a compact and robust design for portable use. They can be used indoors and outdoors, and are perfect for a range of events, including; sports days, outdoor events, event marshalling, festivals and public protests.

Explore Our Range of Megaphones

We offer a selection of high-quality loudhailers, varying in size and power to suit different requirements. For instance, we provide 20W megaphones that produce coverage of 0.25-5km. In comparison, our 65W megaphones have a 1.0-1.2km range. The power that you require for your loudspeaker will depend on your usage purposes, for example, a small gathering would suit a compact lower-power megaphone, whilst a large school sports day may require a more powerful model. The exact coverage you receive will also vary depending on environmental conditions.

Our megaphones include a selection of useful features. For example, many feature a shoulder strap so that the device can be carried easily, giving you a portable megaphone. Typically they also have adjustable volume control so that you can adjust the output to suit different environments. Many models additionally include a detachable anti-howl microphone on a coiled lead as well as a megaphone with siren noises included.

Furthermore, most of our bullhorn megaphones include a siren function. This plays a pre-recorded alarm, which is very useful in any emergency situation. Often a record function is also featured, allowing you to pre-record messages and replay them easily, rather than having to repeat yourself. This is useful as a microphone with mic separate to the horn allows you to raise the speaker higher up, but you can speak from an easier position. If you plan to use a loudhailer for extended periods of time, a portable megaphone with microphone is key.

Our high-end loudhailers additionally include extra useful features, such as Bluetooth technology, which allows you to pair smart devices and stream audio wirelessly. An in-built MP3 player with USB and SD card slots may also be featured, enabling you to easily play your MP3 files. In addition, some models include an AUX input to connect additional audio equipment.

Battery Powered Megaphone For Portable Use

Our loud megaphones are powered by batteries, making them ideal for on-the-go use. The batteries are needed to power the loudspeaker’s integrated amplifier which amplifies your vocals over a long distance.

The use of batteries means that our bullhorn megaphones are perfect for portable use. The battery requirements may differ between models so take a look at our product specifications for more information on the batteries needed. You will see that several options come with batteries included for your convenience, and some also contain spare megaphone rechargeable batteries so that you can use the megaphone for a long duration without needing to worry about batteries running out.

Options To Play Music

We offer a selection of loudhailers that are designed for music playback in addition to announcements. These models include features such as Bluetooth connectivity, providing the option to pair a smart device to wirelessly stream music. Often they also feature a USB and SD card slot, so that you can play MP3 files, and an AUX input may also be included for connecting additional equipment.

Events and Occasions For Megaphone Use

The occasions when a loud hailer can be used are numerous, with the benefit of being able to be heard over distance, over louder noises being a real plus.

Public Speaking at Events:

Megaphones play a vital role in public speaking at outdoor events where natural acoustics and environmental noise make it difficult to communicate. At rallies, protests, and parades, organisers and speakers need to ensure that their voices reach large audiences, and megaphones provide an easy and portable solution. Whether it’s giving a motivational speech, sharing important announcements, or organising the crowd, the megaphone helps project voices effectively without the need for complex sound systems.

In sports events, particularly outdoor games, megaphones are frequently used by referees, coaches, and commentators to ensure that players and audiences can hear important updates and instructions. From school sports days to large-scale tournaments, the ability to quickly and clearly convey information, such as game rules or safety measures, is crucial to maintaining order and flow. Megaphones are also beneficial for addressing sudden changes in schedule or weather conditions during these events.

Emergency Situations:

In emergencies, clear and timely communication can make the difference between safety and chaos. Megaphones are an essential tool for emergency personnel, including police, firefighters, and search-and-rescue teams. They are used to give instructions during evacuations, ensuring that people are aware of escape routes, hazards, or critical safety information. Whether it’s directing large groups out of a dangerous building or communicating over the sound of sirens and commotion, megaphones ensure that instructions are heard loud and clear.

In rescue operations, especially in large or crowded areas, emergency megaphones help responders communicate efficiently with each other and the public. Firefighters might use them to guide trapped individuals towards exits, while search-and-rescue teams employ them in natural disaster zones to coordinate efforts or call out to potential survivors. Their portability and ease of use make them ideal for these fast-paced, high-stress environments, where every second counts.

Crowd Control:

Megaphones are widely used by law enforcement and security personnel to manage crowds during public events, protests, or emergencies. They are a voice amplifier that enables authorities to give clear, authoritative instructions from a distance, which is essential when managing large groups of people. Whether guiding crowds through designated exits or directing them away from restricted areas, the loud amplification from a crowd control speaker ensures everyone can hear the necessary commands.

During large gatherings, such as concerts or festivals, security teams rely on megaphones to enforce safety protocols and manage any potential unrest. They help maintain order, especially in situations where crowd behaviour may become chaotic or when individuals need to be moved quickly for safety reasons. The ability to give clear, consistent instructions using a megaphone reduces confusion and helps prevent panic.

School and Sports Events:

At school sports days, field trips, or other outdoor activities, teachers and coaches often use megaphones to ensure their instructions reach all participants clearly. With children spread across large fields or open spaces, megaphones are invaluable in directing teams, starting races, or giving out safety instructions, acting as a voice amplifier for teachers. They provide a simple yet effective way for organisers to maintain control over large groups and ensure everyone is on the same page.

In competitive sports events, megaphones are used by coaches and referees to communicate with players from the sidelines. This is especially important during practice sessions, where feedback and instruction need to be heard over the noise of play. They also serve as a tool for engaging with audiences, making announcements, or celebrating achievements, ensuring that everyone can stay informed and involved in the event.

Protests and Rallies:

In protests and rallies, megaphones are a critical tool for activists to spread their message to a large audience. Whether leading chants, delivering speeches, or coordinating group movements, a shouting horn ensures that their voices are heard clearly, even in noisy, crowded environments. The amplification provided by megaphones allows leaders to communicate their message over long distances, uniting crowds around a common cause, so you’ll find that the best megaphone for protests are the larger, more powerful types.

Additionally, organisers use megaphones to manage the logistics of a protest or rally, directing participants, sharing schedules, or alerting the group to changes in plans or locations. In high-energy or tense environments, where emotions and noise levels run high, the megaphone is vital for maintaining order and ensuring that everyone receives important updates. It also helps rally leaders respond swiftly to the needs of the crowd, keeping the event organised and on track.

Construction Sites:

On construction sites, where heavy machinery and equipment generate constant noise, megaphones are crucial for supervisors to communicate with workers. Instructions regarding safety procedures, task updates, or potential hazards need to be conveyed clearly to ensure that everyone stays safe and operations run smoothly. Megaphones act as a voice amp, allowing project managers to issue real-time instructions without needing to shout over the sound of drills, cranes, or engines.

They also play an important role during emergency drills or actual site evacuations. In the event of an accident, fire, or structural hazard, a megaphone allows site leaders to quickly alert workers and direct them to safety. Clear, loud communication in such a noisy and potentially dangerous environment can help reduce the risk of accidents and improve overall safety and efficiency.

Boat and Water Sports:

When it comes to water-based activities such as boating, kayaking, or lifeguard operations, megaphones are essential for communicating with people over long distances or above the noise of waves and wind thanks to its directive speaker. Traditionally metal speaking trumpets were used at sea, but this has since been replaced with electric loudhailers today. Lifeguards use them to alert swimmers to dangerous conditions or give instructions to those far out in the water. Megaphones are also used in rescue operations, ensuring that people in distress can hear life-saving instructions.

For organisers of water sports and activities, such as sailing regattas or jet ski races, megaphones help provide instructions or relay important race information to participants. Given the distance between boats or the water's natural noise, megaphones are the most effective way to communicate with competitors or crews during these events. They can signal the start of a race, notify participants of rule changes, or direct them toward safe docking areas.

Guided Tours:

Megaphones are frequently used as a tour guide voice amplifier, especially in large or outdoor environments, where it’s difficult for a group to stay close enough to hear the guide clearly. Whether leading a historical tour, nature walk, or city exploration, guides can rely on megaphones to ensure that every participant hears important facts and directions. This helps create a more engaging and informative experience for tourists, allowing them to enjoy the tour without struggling to catch the guide’s words.

In larger, busier environments, such as theme parks or zoos, megaphones allow guides to keep their groups organised, giving instructions about meeting points or schedules. They also ensure that safety information is heard, particularly when a large number of visitors are involved. Using a megaphone ensures that the guide maintains control over the group, while participants feel more connected and informed throughout the experience.

Political Campaigns:

Politicians and campaigners often use megaphones during canvassing efforts and outdoor campaign events to reach their audience clearly. They are especially useful when giving speeches in open areas or addressing a crowd that cannot gather close enough to hear without amplification since a megaphone is essentially a portable handheld PA system. Megaphones allow candidates to engage with supporters, share their political message, and energise a crowd without the need for complex sound equipment.

In addition to speeches, campaign teams use megaphones to organise volunteers and direct foot traffic at events. Whether encouraging voters to engage or giving instructions to campaign workers, the megaphone ensures that communication remains efficient and accessible. In high-energy political environments, the ability to project a clear, strong voice helps create a sense of unity and purpose within the campaign.

Festivals and Parades:

Megaphones are commonly used by organisers of festivals and parades to communicate with participants and audiences. At large-scale events, where music, chatter, and movement can create a chaotic atmosphere, megaphones act as an announcement horn as they help relay important information such as schedules, safety instructions, or general announcements. Organisers can use them to ensure the smooth flow of events, keeping everything on time and ensuring the audience remains informed.

Parade leaders, in particular, rely on these voice projection devices to direct performers, floats, or participants throughout the event. They can give real-time instructions to ensure that the parade maintains its intended pace, and alert participants to any route changes or safety concerns. This ensures that the event remains well-coordinated, allowing everyone involved to enjoy the experience without confusion or disorganisation.

Frequently Asked Questions

Why Are Megaphones Called Megaphones?

The term ‘megaphone’ was first coined by Thomas Edison in 1878 to describe a horn-shaped speaking trumpet to help people with hearing difficulties to hear better. Since then megaphones have evolved greatly and now include an electrically powered amplifier, making them ideal for public address.

What Is The Difference Between A Microphone And A Megaphone?

Both microphones and megaphones are used to amplify vocals, however they are significantly different. A megaphone is self-contained and features an in-built amplifier, enabling it to amplify the voice of the speaker. In comparison, a microphone converts a voice into electric pulses which can be converted into audio signals by a speaker. A microphone therefore needs to be connected to a separate device, such as an active speaker, to amplify the vocals.

Why are Megaphones Shaped Like Funnels?

Megaphones are shaped like funnels—a design that is wider at the mouth end and narrows toward the handle—for effective amplification and direction of sound. This shape isn't arbitrary; it serves several important acoustic purposes.

Sound waves produced by your voice need to transition from the small area of your mouth to the much larger area of the open air. This transition involves a change in acoustic impedance. A sudden change would cause much of the sound energy to reflect back toward the source, reducing the sound's loudness in the desired direction. The gradual widening of the funnel shape provides a smooth transition, matching the impedance between your vocal tract and the open air. This allows more sound energy to be transmitted forward, effectively amplifying your voice.

The funnel shape channels the sound waves, focusing them in a specific direction rather than allowing them to disperse in all directions. This focused projection makes your voice carry further and reach a larger audience without significant loss of intensity.

The expanding shape of the megaphone allows sound waves to spread out smoothly into the open air. This efficient radiation minimises the energy lost to the surroundings and maximises the sound that reaches listeners.

Beyond acoustics, the funnel shape is practical for handheld use. It provides a wide opening for sound emission without making the device cumbersome to hold.

What are Megaphones Used For?

Megaphones are used to amplify and direct a person's voice, allowing them to communicate loudly and clearly over long distances or to large groups of people. They are commonly employed in public events, emergency situations, protests, sports activities, and any setting where enhanced vocal projection is needed without electronic amplification.

What is the Difference Between a Megaphone and a Loudspeaker?

In essence, there is no definable difference between a megaphone and a loudspeaker. The term refers to the same item. Some references on the internet for a megaphone puts it as a name for an analogue conical-shaped device that one shouts into, a bit like the old-fashioned speakers film directors are depicted with using, however, this isn’t necessarily the case, and nowadays a megaphone and loudspeaker both refer to a long-range acoustic device.

What is the Range of a PA Horn in a Noisy Environment?

The effective range of a PA horn in a noisy environment typically ranges from 50 to 150 meters (approximately 160 to 500 feet). This range can vary widely based on power output, wattage, horn design, background noise levels and any obstructions.

Do Megaphones Need Batteries?

Yes, our range of megaphones require batteries to operate. Each megaphone features an in-built amplifier to magnify and direct your voice, and this is powered by batteries. This means that you can easily use a megaphone portably, and in outdoor settings without being confined by proximity to a power supply. For details on battery requirements take a look at the product specification. Many of our models come with batteries for your convenience.

Can A Megaphone Play Music?

Some megaphones are designed to be suitable for music playback. These include a music function and may feature Bluetooth technology for wireless streaming of music from a paired smart device. They may also contain in-built USB and SD card slots, enabling you to easily play MP3 files.

Are Megaphones Illegal?

Megaphones are not illegal in the UK; however, their use is regulated to prevent noise pollution and public disturbance. However there are some key points to consider:

Under the Control of Pollution Act 1974, local authorities have the power to restrict the use of amplified sound equipment, including megaphones, in public places. Using a megaphone in a manner that causes a nuisance or annoyance can lead to fines or confiscation of the equipment.

Some local councils have specific bylaws that prohibit or restrict the use of megaphones without prior permission. This is especially common in residential areas, near hospitals, schools, or other sensitive locations.

During protests, demonstrations, or public events, the police may impose conditions on the use of megaphones under the Public Order Act 1986. Failing to comply with these conditions can result in legal action.

Excessive noise from megaphones can be considered a statutory nuisance under environmental health regulations. Complaints from the public can prompt investigations and enforcement actions.

If you plan to use a megaphone in a public space, it's advisable to check with local authorities by contacting the local council to understand any specific regulations or permissions required in the area. Also, use your megaphone responsibly. Be mindful of the volume and duration of use to minimise disturbance to others.

Can You Stack Megaphones?

While it's physically possible to stack megaphones by placing one in front of another, doing so does not effectively amplify sound beyond what a single megaphone provides. In fact, stacking megaphones can lead to sound distortion and reduced efficiency. Megaphones are designed to project sound optimally when used alone; adding another megaphone can interfere with the sound waves due to misalignment and impedance mismatches. Therefore, stacking megaphones is generally not practical or beneficial for increasing vocal projection.

What are the Best Features of an Emergency Megaphone?

An emergency megaphone is an essential tool for effective communication during crises, public gatherings, or any situation that requires directing instructions to a large audience. The best emergency megaphones typically have powerful amplification,and message recording and playback, along with a loudspeaker siren.

How Does a Speech Amplifier Improve Communication in Large Areas?

A megaphone improves communication in large areas by amplifying the speaker's voice, allowing it to reach a broader audience over a significant distance. It works by converting sound waves from the speaker’s voice into electrical signals, which are then amplified and projected through a horn-shaped opening. This shape helps to direct and focus the sound, minimizing dissipation. The increased volume makes it easier for people in noisy environments or large spaces to hear and understand the message, even over long distances. Megaphones are especially useful in open-air settings, during events, or in emergencies, where natural voice projection might not be sufficient.
