A Receiver with Improved Conducting Mechanism

Abstract

A telephone receiver with an improved conduction mechanism comprises an electromagnetic shielding housing, vibration membranes, an electromagnetic conversion mechanism, and a power transmission mechanism. The vibration membranes and the electromagnetic conversion mechanism are arranged inside the electromagnetic shielding housing. The electromagnetic conversion mechanism comprises an armature; and the vibration membranes are symmetrically arranged on the upper and lower sides of the electromagnetic conversion mechanism along a vibration direction of the armature, and connected to the armature in a transmission manner by using the power transmission mechanism. In the telephone receiver with the improved conduction mechanism according to the present invention, a special transmission mechanism is used to transmit vibration output of the electromagnetic conversion mechanism to the vibration 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 vibration 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 the ho...

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.
