Talking about the classification of walkie-talkie headsets

Earphones play a great role in the use of walkie-talkies, not only can liberate the hands of the caller, but sometimes also play a role of covert calls, which is related to their specific working environment. At present, with the continuous development of the walkie-talkie market, the headset market has also attracted people's attention. It can be said that there are many brands of walkie-talkie headsets, and the categories and methods of use are also different. Sometimes the configuration of the headsets of different brands and different models is not the same, which can easily confuse consumers. In this article, we classify the headphones that are often worn in the use of walkie-talkies, hoping to give users some help and reference.

1. From the way of wearing, there are earplug, hanging, and head-mounted (light, medium, and heavy)

Earbud and ear-hook earphones are small in size and easy to carry. They are currently the most popular earphones on the market, and they are also the most commonly used earphones in walkie-talkies. There are generally two forms of combination microphone and built-in microphone. Cost-effective earplugs and ear-hook headphones allow users to use the walkie-talkie without removing the walkie-talkie from the carrying case, thereby improving the user's work efficiency. Suitable for retail, hotel, catering and other industries.

Headwear is generally relatively large and has a certain weight, so it is not convenient to carry, but its expressive force is strong and it is not subject to external interference. Headphones create conditions for hands-free communication, so they are an effective tool to greatly improve work efficiency. Contains three types: light headset, medium headset, and heavy headset. Lightweight headsets create conditions for high-definition, hands-free, and separate two-way communication, while also increasing comfort, and can be used for extended wear in moderate noise. Applicable to entertainment industry, retail industry, sports, leisure industry. While providing high-definition speech, medium-sized headsets also have limited sound insulation. They are a necessary tool for unobstructed and clear dual-ring communication in harsh noisy environments. It is suitable for construction industry, manufacturing industry, petrochemical industry and air transportation industry. The heavy-duty headset includes a noise-cancelling rotating microphone, which can be worn with or without a helmet. Sending and receiving calls are used for noise strength up to 125dB. Suitable for mining, construction, manufacturing and air transportation.

2. From the sound conduction method, it is divided into several categories, such as conventional, air duct, bone conduction, and throat vibration.

Conventional headset (microphone) means that the electro-acoustic signal of the receiver is transmitted to the ear through the wire (the speaker is sounded, and the voice is the sound wave transmitted through the air to the microphone to convert the electro-acoustic signal to the transmitter. It is the most common headset in the market. .

Air tube earphone means that the electroacoustic signal of the receiver is converted into sound wave and then transmitted to the ear through the plastic air tube. Its characteristics are: a. This vibration sound wave is transmitted through the hollow tube, which can filter the distortion and other noise generated by the speaker. In addition, the tube conducts sound, the human ear does not need to touch the speaker at close range, 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 concealedly, so it is also selected for some special working people (such as entertainment staff and security staff) and people who need to use it for a long time.

Bone conduction headphones have high quality and high noise immunity, and its microphone is a vibrating microphone. It uses a high-sensitivity vibration sensor to pick up the human body tissue vibration caused by the vibration of the vocal cords when a person speaks, and convert the vibration into electrical signal processing. The guided microphone is insensitive to sound waves propagating in the air and has superior noise resistance. It is not disturbed by wind cut sound, unique design, soft texture, convenient and comfortable to wear.

Throat vibration earphones use the throat vibration brought by the vibration of the vocal cords to be transmitted to the pickup and converted into electro-acoustic signals to the transmitter. Throat and ear bone microphones, because they are directly transmitted from the throat and ear bones to the pickup, they can prevent environmental noise from entering the transmitter, but it is different from the sound transmitted by the air, so the other party will feel that the sound will be somewhat different It is not the same, that is, the so-called fidelity is not high, but the clear call is the main purpose of communication.

In addition, there is an invisible headset on the market. It is a special kind of earphone that can be completely concealed after using 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 during covert operations. Security personnel, public safety personnel and private investigators can communicate through this imperceptible device. Although it is small and exquisite, it can provide a full set of audio functions, including automatic squelch, automatic gain control and automatic noise filtering.
