Embodiment Construction

[0039] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions are used in this specification for the purpose of description only.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used in the description of the present inv...

Abstract

Disclosed in embodiments of the present application is a receiver, comprising: a lower housing; a moving-iron unit disposed in the lower housing; a connecting rod with one end connected to the moving-iron unit; a diaphragm comprising a support, a thin film, and a vibrating wing, the thin film being fixed to the support, the vibrating wing being fixed to the thin film, and one surface of the support being fixed together with the lower housing by soldering; and an upper housing fixed together with the other surface of the support by soldering, wherein the upper housing is further provided with a sound outlet. By means of the above solution, the bonding strength of different parts of the receiver is enhanced and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of moving iron receivers, in particular to a receiver. Background technique [0002] The moving iron receiver is mainly used in audio equipment such as earphones and hearing aids. Due to its small size and good high-frequency performance, it is favored by customers. At present, the assembly of the receiver is divided into two parts, the front cavity part and the rear cavity part. figure 1 As shown), the way and strength of the connection between the two directly determine the sound pressure and high-frequency performance of the receiver, and due to the design requirements of the product, it is necessary to put the diaphragm into the upper shell, and then the operator puts it on the microscope. Next, use a glue applicator to apply glue along the junction of the surrounding edges of the diaphragm and the upper shell, and then bake and cure the glue at a high temperature to bond the two together. [0003] In ...
