Description

High-strength miniature moving-coil receiver

Technical Field

The utility model relates to a receiver equipment technical field specifically is a miniature moving coil type receiver of high strength.

Background

The Receiver is also called Receiver, and English is Receiver. An electroacoustic device for converting an audio electric signal into an acoustic signal without acoustic leakage (or a 3.2 type high/low leakage loop according to ITU standard) is widely used in communication terminal devices such as mobile phones, fixed phones, and hearing aids to reproduce audio (voice and music). The receiver is a moving-coil receiver, and the working principle (physical principle) of the receiver is similar to that of a traditional moving-coil loudspeaker: the voice coil is driven by the changing electromagnetic field force (Lorentz force) generated by the changing current to vibrate up and down and drive the vibrating membrane to drive the front and back air to generate sound waves. Since it is the electro-acoustic characteristic of the pressure field that needs to be output, the receiver is usually configured with front and rear acoustic chambers and acoustic damping for adjusting the audio frequency characteristic. Although there are many other receiver types based on the transduction principle, so far, the moving coil type receiver has become the mainstream electroacoustic device of the audio terminal in the mobile phone and the fixed phone due to its higher performance-price ratio, mature production process, variable multi-end external dimension and leading-out mode. The receiver converts the amplified electrical signal into an acoustic signal. The processed and amplified audio signal is sent to the receiver, converted into a sound signal by the receiver, and then output to the external auditory canal through the ear hook, the sound transmission tube and the like. The existing telephone receiver device is not easy to detach and install, has high maintenance cost and poor dustproof and waterproof performance, easily causes moisture and dust in the air to enter and causes the damage of internal elements, and is low in strength and easy to damage when being collided by objects. Therefore, a high-strength miniature moving-coil telephone receiver is provided.
