A terminal and its receiver

Abstract

The invention provides a terminal and a receiver thereof. The receiver includes a first cover, a second cover, a diaphragm and a sound hole, wherein the diaphragm is arranged between the first cover and the second cover, and the first cover and the second cover cooperate to form the receiver. Acoustic cavity, and the acoustic cavity includes the front acoustic cavity defined by the diaphragm and the first cover, and the rear acoustic cavity defined by the diaphragm and the second cover, and the sound outlet is arranged at the junction of the first cover and the second cover and connected with the The speaker holes of the terminal are aligned, and the sound hole is sandwiched between the first cover and the plane where the diaphragm is located. Through the above method, when the receiver of the present invention is installed in the terminal, it can reduce the size it occupies in the length direction of the terminal.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a terminal and a receiver thereof. Background technique [0002] The receiver is an electroacoustic device that converts electrical signals into sound. According to its working principle, it can be divided into carbon crystal type, capacitive type, moving iron type and moving coil type. At present, dynamic receivers have been widely used in terminal technology fields such as smartphones. [0003] figure 1 It is a schematic diagram of the front structure of the receiver in the prior art, figure 2 yes figure 1 A cross-sectional view of the receiver shown along the direction A-A. refer to figure 1 and figure 2 , the front cover 110 and the rear cover 120 cooperate to define the sound cavity X of the receiver 100 , and the sound outlet 111 is opened on the front cover 110 of the receiver 100 . When the receiver 100 is installed on a terminal such as a smart phone, since ...

AI Technical Summary

Problems solved by technology

However, the larger planar area of ​​the front cover 110 will inevitably lead to a larger width of the receiver 100, thereby resulting in a larger size occupied by it in the length direction of the terminal, which will easily cause the length of the terminal to be too long and not commensurate with its width. Affect the appearance of the whole machine
