Abstract

The invention discloses a sounding device and an electronic terminal. The sounding device comprises a front cover and a shell which are combined together; a vibrating diaphragm is installed in a cavity defined by the front cover and the outer shell, an elastic sealing piece is integrally combined on the front cover, a step structure matched with the front cover and the outer shell is formed on theassembling face of the front cover and the outer shell, at least one gluing area is arranged on the step structure, the gluing area is configured to be used for containing glue, and the front cover and the outer shell are bonded and fixed through the glue. The sounding device not only has good sealing performance, but also is simple in assembly process; meanwhile, the drawing force of the front cover and the shell is improved in a gluing mode, the combination firmness degree of the front cover and the shell can be effectively enhanced, and glue overflowing is prevented.

Description

technical field

[0001] The present invention relates to the technical field of electroacoustic products, and more specifically, to a sound generating device and an electronic terminal. Background technique

[0002] Smartphones and other electronic terminals will integrate a sounding device, but when the sounding device is assembled with the electronic terminal, in order to prevent water from entering the electronic terminal through the gap between the sounding device and the housing of the electronic terminal, causing the function of the electronic terminal to fail, the sounding device needs to be adjusted. The gap between the device and the housing is sealed.

[0003] A sealing method is provided in the prior art, such as figure 1 and 2 As shown, the soft rubber (elastic seal 6') and the housing 2' are formed by double-shot injection molding, the front cover 1' and the diaphragm 3' are bonded through the glue-coating area 4', and at the same time, the outer ring of the fr...
