The earphones play a great role in the use of the walkie-talkie machine, which not only liberates the hands of the caller, but also plays the role of covert calls, which is related to its specific working environment. At present, while the market of walkie-talkie machines continues to develop, the headset market is also receiving much attention.
The walkie-talkie earphone products can be described as many brands, and the classification and use methods are also different. Sometimes the configuration of the headphones of different brands and different models is not the same, which is easy to cause confusion. Let’s classify the headphones that are often worn in the use of the walkie-talkie, and quickly put them into the bag.
First, from the wearing method to be divided into: earplugs, ear-hook, head-mounted (light, medium, heavy)
The earphone type and ear-hook type earphones are small in size and convenient to carry, and are currently very popular earphones on the market, and are also the most commonly used earphones in the current walkie-talkie. There are generally two forms of combined microphones and built-in microphones. Cost-effective earbuds and ear-hook headphones allow users to use the walkie-talkie without removing the walkie-talkie from the carry-on case, thus increasing user productivity. Suitable for retail, hotel, catering and other industries.
Headwear is generally large and has a certain weight, so it is not convenient to carry, but its performance is strong and it is less affected by external interference. Headphones create conditions for hands-free communication and are therefore an effective tool for greatly improving work efficiency. It includes three types of lightweight headphones, medium-sized headphones, and heavy-duty headphones.
Lightweight headphones add comfort to high-definition, hands-free, and split two-way communication while being worn in moderate noise. Suitable for the entertainment industry, retail industry, sports, leisure industry.
The medium-sized headphones provide high-definition voice and limited sound insulation, making them a necessary tool for unobstructed and clear two-way communication in noisy environments. It is suitable for the construction industry, the manufacturing industry, the petrochemical industry and the air transport industry.
Heavy-duty headsets include a noise-cancelling rotary microphone that can be worn with or without a helmet for noise levels up to 125dB. Suitable for mining, construction, manufacturing and air transport.
Second, from the sound transmission method is divided into: conventional, air duct, ear bone conduction, throat vibration and other major categories
The conventional earphone (microphone) means that the electroacoustic signal of the receiver is transmitted to the ear (horn) through the wire, and the voice is sent by the air-transmitted sound wave to the microphone to be converted into an electroacoustic signal and sent to the transmitter, which is the most common in the market. headset.
The air duct earphone means that the electroacoustic signal of the receiver is converted into sound waves and transmitted to the ear through a plastic air duct. Its unique features are:
a. This vibrating sound wave is transmitted through a hollow conduit to filter distortion and other noise generated by the speaker. In addition, the sound is transmitted by the catheter, and the human ear does not need to be in close contact with the speaker, and the discomfort caused by the magnetic radiation of the speaker and the heat generated by the speaker coil working in the magnet for a long time can be avoided.
b. Because the air duct is made of transparent material, it is easy to use invisibly. Therefore, it is also selected for people with special work (such as staff and guards in entertainment venues) and people who need to use it for a long time.
The ear bone conduction earphone has high quality and high noise resistance, and its microphone is a vibrating microphone. It uses a high-sensitivity vibration sensor to pick up human tissue vibration caused by vocal cord vibration when a person speaks, and convert the vibration into electrical signal processing. The bone conduction microphone is insensitive to sound waves propagating in the air and has superior noise immunity. Unaffected by wind cuts, unique design, soft texture, comfortable and comfortable to wear.
The throat vibration type earphone uses the throat vibration brought by the vocal cord vibration to transmit to the pickup, and converts it into an electroacoustic signal and sends it to the transmitter. The laryngeal and ear bone microphones are transmitted directly from the throat and the ear bones to the pickup to prevent external environmental noise from entering the transmitter, but the sound transmitted by the air will be somewhat different, so the other party will feel that the sound will be somewhat The same, the so-called fidelity is not high, but the clear call is the main purpose of communication.
In addition, there is a hidden headset on the market. It is a special type of earphone that can be completely concealed with a miniature wireless receiver. All information received by the user’s two-way radio is relayed to the wireless headset in the user’s ear in the form of radio waves, which can be conveniently hidden under the user’s clothing in secret operations. Security personnel, public safety personnel and private detectives can communicate through this undetectable device. It is small enough to provide a full range of audio features, including automatic squelch, automatic gain control and automatic noise filtering.
