Runway shaped waterproof intercom horn

1、 Unique design and construction

The runway shaped waterproof intercom speaker presents a unique runway shape in appearance, which is not designed to pursue visual uniqueness, but rather contains profound engineering considerations. Compared to traditional circular or square speakers, the runway shaped design can better adapt to the limited and irregular spatial layout inside walkie talkies, achieving more compact and efficient integration, and providing strong support for the overall miniaturization and lightweight development of walkie talkies.

From the perspective of internal structure, the runway shaped waterproof walkie talkie horn is mainly composed of key components such as diaphragm, voice coil, magnet, grid, and front and rear chambers. As the core component of the horn, the diaphragm, like the lead singer in a band, shoulders the responsibility of converting electrical signals into sound. It is usually made of thin and highly elastic thin film materials carefully selected to have excellent acoustic performance. When receiving audio electrical signals, these materials can quickly and accurately generate vibrations, which in turn push the surrounding air to form the sound we hear. Different materials of diaphragms, such as paper diaphragms, plastic diaphragms, metal diaphragms, etc., will give speakers different timbre characteristics. The paper diaphragm has a warm and natural sound, which can effectively reproduce human voices; Plastic diaphragms have the advantages of low cost and light weight, and are widely used in mid to low end products; Metal diaphragms, with their high rigidity and low mass characteristics, can achieve wider frequency response and higher sound pressure levels, and are commonly used in high-end dedicated walkie talkie speakers.

The voice coil is like a "power engine" of the diaphragm, tightly surrounding the edge of the diaphragm and firmly connected to it. When audio current passes through the voice coil, according to the principle of electromagnetic induction, the voice coil will be subjected to Ampere force in the magnetic field generated by the magnet, thereby driving the diaphragm to vibrate together. The wire material, number of turns, and wire diameter of the voice coil can have a significant impact on the performance of the speaker. Using high-purity copper material as the wire can reduce resistance, improve current transmission efficiency, and thereby enhance the sensitivity of the horn; Increasing the number of turns can enhance the force on the voice coil in the magnetic field, improve the output power of the horn, but at the same time, it will also increase the inductance of the voice coil, which has a certain impact on the high-frequency response; Reasonable selection of wire diameter can control the quality of the voice coil while ensuring the current carrying capacity, ensuring that the diaphragm can vibrate quickly and flexibly.

Magnet is a key component that generates a magnetic field, like injecting a "soul" into a horn. It is mainly divided into two types: permanent magnets and electromagnets. Permanent magnets have the advantages of simple structure, no need for external power supply, and high stability, and are widely used in most walkie talkie speakers. Electromagnets, on the other hand, can precisely control the magnetic field strength by adjusting the current, thereby achieving flexible adjustment of horn performance. However, due to the need for additional power drive circuits, their structure is relatively complex and their cost is also high. The magnetic field strength, uniformity, and relative position between the magnet and the voice coil directly determine the electroacoustic conversion efficiency and sound quality performance of the speaker. A strong and uniform magnetic field can make the voice coil smoother when subjected to force, reduce distortion, and improve the clarity and fidelity of sound.

The grid covers the front of the speaker, like a loyal guardian, providing better protection for the diaphragm and effectively preventing direct damage to the diaphragm from external objects. At the same time, it also plays the role of a "sound conditioner", which can filter and modify the sound to a certain extent, reduce the interference of noise, and make the sound purer and clearer. The design parameters such as mesh material, mesh size, and shape all have an impact on the propagation and diffusion of sound. For example, using a metal mesh material has good mechanical strength and protective performance, and can also enhance the appearance and texture of the speaker to a certain extent; Reasonable design of mesh size and distribution can optimize the frequency response of sound, enabling better propagation of sound in specific frequency bands.

The front and rear chambers, as the cavity parts of the horn, may seem simple, but they actually play a crucial role in the sound characteristics of the horn. They are like a stage for sound, and through reasonable design and adjustment, the interpretation of sound can be achieved. The size and shape of the front cavity can affect the radiation direction and diffusion angle of sound. A larger front cavity can make sound more concentrated and propagate forward, making it suitable for use in scenarios that require long-distance sound transmission; The rear cavity mainly affects the low-frequency response of the sound. By adjusting the volume and internal structure of the rear cavity, the sound output of the low-frequency part can be enhanced or weakened, making the sound of the speaker more rich and full. In some runway shaped waterproof walkie talkie speakers, special acoustic materials are also used to fill the front and rear cavities, further optimizing the sound propagation effect, reducing resonance and reflection, and improving the purity of sound quality.

2、 Superior waterproof technology

Waterproof performance is the core advantage of runway shaped waterproof walkie talkie speakers compared to ordinary speakers, and it is also the key guarantee for their stable operation in harsh and humid environments. In order to achieve excellent waterproof effect, the runway shaped waterproof walkie talkie speaker adopts various advanced waterproof technologies and processes, which work together to provide a strong layer of "waterproof armor" for the speaker.

In terms of the overall structural design of the horn, engineers have fully considered the waterproof requirements. Through precise mold manufacturing and strict assembly processes, they ensure that the various components of the horn are tightly adhered to each other, minimizing gaps and holes and preventing moisture from entering from the source. For example, high-precision sealing rubber rings are used at the connection between the outer shell and internal components of the horn for sealing. These sealing rubber rings are usually made of rubber materials with good weather resistance, water resistance, and elasticity, which can maintain good sealing performance during long-term use and effectively prevent moisture infiltration. At the same time, special waterproof joints and sealing processes are also used in key areas such as the outlet of the speaker to ensure that there are no channels for moisture to enter while connecting the wires to the internal circuit of the speaker.

In addition to structural sealing, waterproof coating technology is also an important means to improve the waterproof performance of speakers. Apply a special waterproof coating evenly on the surfaces of key components such as the diaphragm, voice coil, and magnet of the horn. This waterproof coating has extremely low surface tension and good hydrophobicity, which can quickly form water droplets and slide off when water comes into contact with the coating surface, thereby avoiding water from corroding the components. At the same time, the waterproof coating also has good insulation performance and chemical stability, which will not have any negative impact on the electroacoustic performance of the speaker, ensuring that the speaker can work normally in humid environments. For example, some runway shaped waterproof walkie talkie speakers use nanoscale waterproof coating technology, which has a thickness of several nanometers to tens of nanometers, but can provide superior waterproof performance. At the same time, it also has self-cleaning function, which can effectively prevent dust and dirt from adhering to the surface of the speaker, further improving the reliability and service life of the speaker.

In addition, in order to further improve the waterproof level of the speakers, some runway shaped waterproof walkie talkie speakers will also integrate waterproof sound permeable membranes inside. Waterproof acoustic membrane is a polymer material film with a special microporous structure, which has excellent waterproof performance, can effectively block the invasion of moisture, and ensure the smooth propagation of sound. The diameter of the micropores in waterproof and sound transmitting membranes is usually between the nanometer and micrometer levels. These micropores can prevent the passage of liquid water and allow sound waves to penetrate smoothly, achieving a balance between waterproofing and sound transmission. In practical applications, waterproof sound permeable membranes are usually installed at the sound outlet of the speaker, working together with the grid to provide dual waterproof protection for the speaker. At the same time, the waterproof acoustic membrane also has good breathability, which can balance the air pressure inside and outside the horn, prevent membrane deformation or rupture caused by changes in air pressure, and further improve the reliability and stability of the horn.
