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 receiver, which comprises a single body of the receiver and a sound conduit, wherein the diaphragm, the frame and the support of the single body of the receiver constitute the internal cavity of the receiver; the sound conduit is arranged on the body of the single body of the receiver The back includes a sealed end and an open end, the sealed end is communicated with the internal cavity of the receiver through the inner opening of the frame, and the open end is provided with a through hole communicated with the outside. The technical solution of the present invention can make full use of the space on the back of the main body of the receiver, reduce the increase in the volume of the receiver, make the structural size of the receiver meet the needs of use, effectively reduce the resonant frequency of the receiver itself, improve the low-frequency performance of the receiver, and further improve The low-frequency performance of the earphone reduces the limitation of the earphone acoustic design on the appearance design.

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...
