Novel moving-coil telephone transmitter with anti-noise and waterproof characteristics

Abstract

The invention provides a novel moving-coil telephone transmitter with anti-noise and waterproof characteristics and relates to the technical field of electroacoustics. The novel moving-coil telephone transmitter comprises a rear cover, a magnet is fixedly arranged at the bottom of the rear cover, a rear waterproof film is arranged at the bottom of the rear cover, a rear damping plate is fixedly connected to the bottom of the rear waterproof film, a circuit board is arranged below the rear damping plate. The bottom of the rear damping plate is fixedly connected with tone tuning paper and cloth, a front damping plate is arranged below the tone tuning paper and cloth, and a front waterproof film is arranged at the bottom of the front damping plate. The telephone transmitter has good dustproof and waterproof characteristics IP67, and is high in underwater signal transmission quality and good in performance. And the device is corrosion-resistant and is suitable for working in a harsh or severe environment. Compared with the prior art, the telephone transmitter has waterproof and anti-noise capabilities, is wider in application range, and can still keep certain performance under the conditions of water or humidity and severe environment, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to a novel dynamic microphone with anti-noise and waterproof characteristics. Background technique [0002] The principle of the common dynamic microphone in the prior art is as follows: [0003] The sound wave causes the diaphragm and the voice coil to vibrate, the coil cuts the magnetic field lines, generates an electromotive force, and outputs an electrical signal. The dynamic microphone has the characteristics of wide frequency band and low distortion. [0004] However, there are following problems in the prior art: [0005] Ordinary dynamic microphones do not have waterproof and anti-noise capabilities, and their application range is limited. Especially in the case of underwater or wet and harsh environment, the performance will be affected, the life of the product will be shortened, or even damaged. [0006] Based on the above reasons, the inventor proposes a novel...
