Horn speakers are loudspeakers that use a horn to increase their efficiency and directivity. The horn serves as an acoustic transformer between the vibrating element (such as a microphone diaphragm) and the surrounding air. By reducing the impedance mismatch between the vibrating element and the air, the horn amplifies the sound output.
There are several types of horn speakers, including:
To horn loudspeakers, a number of specifications are so important to consider when purchasing, as they affect the performance of the speaker. They include the following:
Maintaining a horn speaker is very key to ensure its durability and optimum performance. Below are some maintenance tips:
Purpose and Application:
Consider the intended use of the horn speaker. Is it for outdoor announcements, indoor public address systems, warning signals, or musical playback? Different applications may require varying sound quality, volume output, and coverage area considerations.
Size and Coverage Area:
Determine the size of the horn speaker based on the area that requires sound coverage. Larger speakers generally offer broader sound dispersion and can produce higher volumes, making them suitable for expansive outdoor environments.
Mounting and Installation:
Consider how and where the horn speaker will be installed. Some models offer versatile mounting options (e.g., wall, pole, or surface mounts) and adjustable angles for optimal sound direction. Additionally, evaluate the ease of installation and whether any mounting accessories are required separately.
Weather Resistance:
If the horn speaker is intended for outdoor use, consider its ability to withstand various weather conditions. Look for speakers constructed with durable, weather-resistant materials like UV-resistant enclosures and waterproof or corrosion-resistant components.
Impedance and Power Handling:
Check the horn speaker's impedance (e.g., 4 ohms, 8 ohms) to ensure compatibility with the connected amplifier or audio system. Also, consider the speaker's power handling capacity, which should align with the amplifier's output to prevent damage and ensure optimal performance.
Directionality:
Horn speakers can be designed to be omnidirectional (sound disperses in all directions) or unidirectional (sound disperses in one direction). Directional speakers are useful in applications requiring focused sound delivery over long distances while minimizing sound spill in surrounding areas.
Budget:
Determine the budget for purchasing a horn speaker. Prices can vary based on factors such as size, construction material, brand, and additional features. Consider the long-term benefits and reliability of the speaker in relation to the initial investment.
It is advisable to have a professional help when installing a horn speaker. However, it is possible to install a horn speaker without professional help. Follow the steps below.
Before starting the installation process, gather all the necessary tools that will be needed during the process. This includes wire cutters, screwdrivers, electrical tape, and horn speaker.
Make sure the car or motorcycle is turned off before starting the installation process. This will help avoid short circuiting.
Find a suitable location to mount the horn speaker. This includes the motorcycle handlebar or the car's front grill. Make sure there is enough space to mount the speaker and also allow enough space for the bolts and screws.
Use a screwdriver to drill holes where the bolts will go through. This makes it easier to mount the horn speaker.
Once the holes are drilled, the next step is to connect the horn speaker to the electrical system of the car or motorcycle. Depending on the type of horn speaker one is installing, it may require a wire to be connected to the battery.
Use a wire cutter to remove part of the electrical wire's insulation. Make sure the wire is similar to the one in the motorcycle or car's audio system. Then, connect the speaker to the electrical system using electrical tape to make a secure connection.
Once the connection is done, users should secure the horn speaker using bolts and screws. Make sure it is tightly fitted to avoid noise and vibrations.
Once the speaker is tightly fitted, test it out to see whether it is working. Turn on the engine and play music to see whether the horn speaker is working.
Once the user is satisfied with the sound quality and volume, use electrical tape to secure all the exposed wires and connections. This helps avoid short circuiting.
