Acoustical generator front cover and manufacturing method thereof

Abstract

The invention provides an acoustical generator front cover which is fixedly connected with an external installation carrier, wherein the front cover comprises a cover body and a gasket arranged on the cover body and connected with the external installation carrier, the cover body is provided with a sound outlet communicated with outside, the gasket is provided with a connecting body connected with the external installation carrier, the center of the connecting part is provided with a communicating hole opposite to the sound outlet, and the connecting part is designed in a spherical surface. A manufacturing method of the acoustical generator front cover comprises the following steps of: providing the cover body with the sound outlet; providing the gasket, wherein the gasket is provided with the connecting part connected with the external installation carrier and designed in the spherical surface and positioned at the center of the connecting part; and enabling the sound outlet to be opposite to the communicating hole so that one surface of the gasket, which is back to the connecting part, is jointed with the cover body, and carrying out injection molding on the gasket and the cover body into a whole to form the required acoustical generator front cover. According to the invention, the sealing property of the external installation carrier such as the acoustical generator front cover, a mobile phone housing and the like is enhanced.

Description

【Technical field】 [0001] The invention relates to a sounder, in particular to a front cover of the sounder and a manufacturing method thereof. 【Background technique】 [0002] In recent years, with the rapid development of mobile communication technology, portable communication devices such as mobile phones have become an indispensable intercommunication tool in people's work and life. Consumers pay more and more attention to voice functions. It is also required to cooperate firmly with other components inside the product, so as to ensure the durability of the product. [0003] The sound generator in the mobile phone is the loudspeaker, which is provided with a front cover connected to the mobile phone casing, and the front cover is provided with a sound outlet that communicates with the outside world. The position of the mobile phone casing corresponding to the sound hole is designed as a through hole or a dust-proof net to transmit the sound of the sound hole to the outsid...

AI Technical Summary

Problems solved by technology

However, the connection surface between the gasket and the mobile phone casing in the related art is usually a plane, and the width is at least 1 mm, which is limited for high-standard acoustic characteristics; The phenomenon of detachment due to vibration

At the same time, the gasket is usually attached to the front cover around the sound hole, and there is a risk of the gasket detaching from the front cover

As a result, the performance of the product will be greatly reduced
