Problems solved by technology

[0004] However, in the four-sided glued structure, the side of the support wall facing the sound channel is made of pure plastic material. Due to the opening of the through hole, the support wall needs to maintain a certain thickness to ensure its support strength. , and this thickness reduces the height of the sound channel, that is, reduces the sound area, thereby affecting the acoustic performance of the speaker box

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Please also refer to Figure 1-3 As shown, the present invention provides a speaker box 100 , which includes an upper cover 1 , a lower cover 2 , a sound emitting unit 3 , a sound guide channel 4 , a supporting wall 5 and a reinforcing sheet 6 .

[0021] The lower cover 2 is closed to the upper cover 1 and jointly encloses a receiving space 10 . The upper cover 1 and the lower cover 2 can be of an integral structure, or can be of a separate structure.

[0022] The sound emitting unit 3 is accommodated and fixed in the accommodation space 10 . The sound emitting unit 3 divides the receiving space 10 into a front acoustic chamber 7 and a rear chamber 101 .

[0023] That is to say, the sound emitting unit 3 and the upper cover 1 are spaced apart and jointly form the front acoustic cavity 7; The rear cavity 101 is described.

[0024] The sound g...

Abstract

The invention provides a loudspeaker box, comprising a lower cover; an upper cover, wherein a storage space is enclosed by the lower cover and the upper cover; a sound production unit stored in the storage space; a sound conduction channel formed in the storage space; an annular supporting wall which stretches along a direction from the upper cover to the lower cover and is used for supporting thesound production unit; and a reinforcement sheet. The side of the supporting wall resisting against the sound conduction channel is equipped with a through hole penetrating the supporting wall. The sound production unit is supported by the supporting wall. A front sound cavity is enclosed by the sound production unit and the supporting wall. The front sound cavity is communicated with the sound conduction channel through the through hole. The front sound cavity and the outside world are communicated through the sound conduction channel. The reinforcement sheet is an annular structure and is fixedly supported by the supporting wall at the side close to the lower cover. The sound production unit resists against the reinforcement sheet to form seal. Compared with the prior art, the loudspeaker box provided by the invention has good waterproofness and excellent acoustic performance.

Description

technical field [0001] The invention relates to a speaker box, in particular to a speaker box used in portable electronic products. Background technique [0002] During the rapid development of portable devices such as mobile phones, people have increasingly strong requirements for product functionality. For speaker boxes, not only are they required to have good acoustic performance, but more and more requirements have been put forward for waterproof performance. [0003] The speaker box of the related art includes an upper cover, a lower cover which is combined with the upper cover to form a storage space, a sound unit accommodated in the storage space and a sound channel formed in the storage space, the sound unit The body and the upper cover form a front acoustic cavity, the sound emitting unit, the lower cover and the upper cover together form a rear cavity, the sound channel and the front acoustic cavity form a front cavity and connect the front cavity The acoustic cav...
