High-sensitivity telephone receiver vibrating diaphragm

Abstract

The invention provides a high-sensitivity telephone receiver vibrating diaphragm which comprises a vibrating diaphragm body. The vibrating diaphragm body comprises a fixing portion, a middle portion and a connecting portion, a fixing zone with fixing protrusions is arranged on the fixing portion, an annular connecting protrusion is arranged on the connecting portion, a connecting groove is formedin the lower end surface of the connecting protrusion, a primary reinforcement portion and a secondary reinforcement portion are arranged on the connecting portion, the primary reinforcement portion comprises a plurality of fan-shaped primary reinforcement protrusions, and the secondary reinforcement portion comprises a plurality of ring-shaped secondary reinforcement protrusions. The high-sensitivity telephone receiver vibrating diaphragm has the advantages that the high-sensitivity telephone receiver vibrating diaphragm is simple in structure and low in processing difficulty; the adhesion areas can be enlarged by the fixing protrusions on the fixing portion, and the connection strength and the stability further can be improved; the connecting protrusion can be correspondingly connected with a voice coil, the position of the voice coil can be clear at a glance after being connected with the connecting protrusion, accordingly, the adhesion areas can be enlarged, and quality detection can be facilitated; the high-sensitivity telephone receiver vibrating diaphragm is provided with the multistate reinforcement portions, accordingly, the rigidity and the strength of the high-sensitivity telephone receiver vibrating diaphragm can be improved, the area of the high-sensitivity telephone receiver vibrating diaphragm can be increased, internal damping can be enlarged, and distortion canbe reduced; the sensitivity of a telephone receiver can be stabilized, and the voice quality can be guaranteed and improved.

Description

technical field [0001] The invention relates to the field of receiver production, in particular to a high-sensitivity receiver diaphragm. Background technique [0002] The receiver is also called the handset, and the English is Receiver. An electro-acoustic device that converts audio electrical signals into sound signals under the condition of no sound leakage (or 3.2 type high / low leakage ring according to ITU standard), widely used in communication terminal equipment such as mobile phones, landline phones and hearing aids , to achieve audio (speech, music) playback. [0003] The principle of the receiver is similar to that of the receiver. They all use the conversion of electricity and magnetism to trigger the vibration and sound part to produce sound. Most of the receivers in use today use the diaphragm and the voice coil as important vibration sound components. Among them, the diaphragm and the voice coil 1. The base body of the receiver is mostly bonded with glue or r...

[0003] The principle of the receiver is similar to that of the receiver. They all use the conversion of electricity and magnetism to trigger the vibration and sound part to produce sound. Most of the receivers in use today use the diaphragm and the voice coil as important vibration sound components. Among them, the diaphragm and the voice coil 1. The base body of the receiver is mostly bonded with glue or resin. When connecting, due to the small contact area, the connection is often unstable, and the traditional diaphragm generally has low rigidity and low sensitivity, which makes the prepared receiver easy to be distorted. , and the sound quality is poor
