Terminal and telephone receiver thereof

Abstract

The invention provides a terminal and a telephone receiver of the terminal. The telephone receiver comprises a first cover body, a second cover body, a vibrating diaphragm and voice outlet holes. The vibrating diaphragm is arranged between the first cover body and the second cover body. A voice cavity is formed by the first cover body and the second cover body in a matched mode and comprises a front voice cavity and a rear voice cavity, wherein the front voice cavity is defined by the vibrating diaphragm and the first cover body, and the rear voice cavity is defined by the vibrating diaphragm and the second cover body. The voice outlet holes are formed in the joint of the first cover body and the second voice body, aligned with loudspeaking holes of the terminal and clamped between the first cover body and the plane where the vibrating diaphragm is located. In this way, when the telephone receiver is installed on the terminal, space, occupied by the telephone receiver, in the length direction of the terminal can be reduced.

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
