Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] Such as Figure 1-Figure 5 As shown together, the receiver provided by the embodiment of the present invention includes a receiver unit body 100 and an acoustic conduit 200; wherein,

[0035] The single body 100 of the receiver includes a diaphragm 101, a copper ring 102, a voice coil 103, a washer 104, a magnet 105, a frame 106, a bracket (Yoke) 107, and an electrical connector 108, wherein the diaphragm 101 and the frame 106 And the bracket 107 constitutes the inner cavity I of the receiver.

[0036] The sound conduit 200 is arranged on the back of the receiver body 100 and includes a sealed end 201 and an open end 202. The sealed end 201 passes through the inner opening 109 of the frame 106 and the inner cavity of the receiv...

Abstract

The invention discloses a telephone receiver which comprises a telephone receiver single body and a sound conduit. A vibrating diaphragm, a basin frame and a support of the telephone receiver single body form a telephone receiver internal cavity. The sound conduit is arranged at the back of the telephone receiver single body and comprises a sealing end and an opening end. The sealing end is communicated with the telephone receiver internal cavity through an inner side opening in the basin frame. The open end is provided with a through hole communicated with the outside. By means of the technical scheme, the space of the back of the telephone receiver single body can be fully utilized, the size of the telephone receiver is reduced, so that the structural size of the whole telephone receiver meets usage requirements, meanwhile, the resonant frequency of the telephone receiver can be reduced effectively, the low-frequency performance of the telephone receiver is improved, the low-frequency performance of an earphone is improved accordingly, and limit of the acoustic design of the earphone on the appearance design is lowered.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a receiver. Background technique [0002] With the wide application of portable electronic products such as high-quality smartphones and Pads, people have higher and higher requirements for earphones that can be used with them. True sound quality performance, so high-fidelity headphones have become a market trend. [0003] The receiver used in the earphone is subject to requirements such as size, impedance, sensitivity, etc. Usually, the equivalent sound quality of its vibration system is usually small, and the compliance of the diaphragm is generally increased to ensure that the receiver has a relatively low resonance frequency f 0 . For example, for a typical receiver with a diameter of 14.6mm, the equivalent sound quality of its vibration system is 20mg, and the compliance is 2.46mm / N, then f 0 is 227Hz. And high-fidelity headphones require the f of the wh...
