Background

With the popularization of mobile terminals and the rapid development of electronic technologies, communication terminal devices (such as mobile phones), mobile computers, tablet computers and other devices are increasingly important in the life of people. The vision is the most important channel for people to obtain information, when various terminals carry out man-machine interaction, the intuitive operation is an important way for improving the user experience, the larger screen occupation ratio can bring the scientific and technological sense and the fashion sense to products, and the continuous pursuit of the larger screen occupation ratio is a main trend of the development of communication terminal equipment.

A receiver is an electroacoustic device for converting an audio electric signal into an acoustic signal, and is widely used in communication terminal devices such as mobile phones, fixed phones, and hearing aids. The receiver is a moving coil receiver, and the working principle is as follows: the voice coil is arranged in a magnetic gap of a magnetic circuit of a permanent magnet, and the current flows to generate driving force, so that the vibrating diaphragm is driven to vibrate in a reciprocating manner to radiate sound waves outwards. At present, a sound hole is generally designed right above a diaphragm of a receiver.
