Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, a sounding device 10 includes a housing 1 with a housing space and a sounding unit 2 placed in the housing 1. The sounding device 10 is provided with a foam retaining wall 5 to separate the housing 1 into front A chamber 4 and a rear chamber 3 opposite to the front chamber 4, the front chamber 4 communicates with the outside world, and the sound emitting unit 2 is placed in the front chamber 4. The rear chamber 3 is filled with sound-absorbing material 6 . More preferably, the sound-generating device 10 is also provided with a packaging bag (not shown) for accommodating and covering the sound-absorbing material 6, the packaging bag is made of foam, and the packaging containing the sound-absorbing material 6 The bag is filled in the rear cavity 3 .

[0014] The shell is divided into a front chamber and a rear chamber opposite to th...

Abstract

The invention discloses a sounding device which comprises a shell with an accommodating space and a sounding monomer placed in the shell. The sounding device is provided with a foam retaining wall for dividing the shell into a front cavity and a rear cavity opposite to the front cavity; the front cavity is communicated with the outside; the sounding monomer is placed in the front cavity; and a sound adsorption material is filled in the rear cavity. Compared with the relevant art, the sounding device has the advantage that the low-frequency sound effect is better.

Description

【Technical field】 [0001] The invention relates to a sounding device, in particular to a sounding device used in portable electronic products. 【Background technique】 [0002] In the process of rapid development of portable devices such as mobile phones, people have increasingly strong requirements for the functionality of products. For the music appreciation function of mobile phones, in order to make the entertainment effect stronger, the mode of music with vibration appears. Therefore, the development of sound-generating devices has also been accelerated accordingly. [0003] A sound-generating device in the related art, which includes a housing with a storage space and a sound-emitting monomer placed in the storage space, the sound-emitting monomer divides the storage space into a front cavity and a rear cavity opposite to the front cavity cavity, and the anterior cavity communicates with the outside world. This structure makes the sounding device have a larger rear cavi...
