Telephone receiver with improved transmission mechanism

Abstract

A telephone receiver with an improved transmission mechanism comprises an electromagnetic shielding housing, vibrating membranes, an electromagnetic conversion mechanism and a power transmission mechanism, wherein the vibrating membranes and the electromagnetic conversion mechanism are arranged in the electromagnetic shielding housing; the electromagnetic conversion mechanism comprises an armature; and the vibrating membranes are symmetrically arranged on the upper and lower sides of the electromagnetic conversion mechanism in a vibrating direction of the armature, and connected with the armature in a drive manner by the power transmission mechanism. According to the telephone receiver with the improved transmission mechanism, the special transmission mechanism is adopted to transmit vibrating output of the electromagnetic conversion mechanism to the vibrating membranes, so that audio output of the telephone receiver is doubled; and the axial vibration of a telephone receiver housing is offset due to opposite movement between the vibrating membranes.

Description

technical field [0001] The invention relates to an electroacoustic conversion device, in particular to a receiver with an improved conduction mechanism. Background technique [0002] Receivers using moving iron units have been more and more used in various fields of people. With the improvement of people's quality of life, the volume requirements of receivers are becoming smaller and smaller, and the requirements for voice quality of receivers are also increasing. However, with the miniaturization of the moving iron unit in the receiver, the electro-acoustic conversion efficiency of the moving iron unit will also decrease. In order to obtain better voice quality, the form of multi-unit combination is currently used to meet the requirements, but it will come The only disadvantages are the increase in production cost and the increase in the size of the receiver. At the same time, the axial vibration of the receiver shell due to the vibration of the diaphragm will cause t...

However, with the miniaturization of the moving iron unit in the receiver, the electro-acoustic conversion efficiency of the moving iron unit will also decrease. In order to obtain better voice quality, the form of multi-unit combination is currently used to meet the requirements, but it will come What is the increase in production costs and the increase in size of the receiver

At the same time, the axial vibration of the receiver shell due to the vibration of the diaphragm will cause the howling of the receiver and affect the output of the receiver's speech quality.
