Embodiment 1

[0028] Please also see figure 1 , figure 2 and image 3 ,in, figure 1 A three-dimensional exploded schematic diagram of Embodiment 1 of the speaker cabinet provided by the present invention; figure 2 for figure 1 The three-dimensional assembly diagram of the speaker box shown; image 3 for figure 2 A sectional view of the speaker cabinet shown along line A-A. The present invention provides a speaker box 100, which includes an upper cover 1, a lower cover 3 that is combined with the upper cover 1 to form a storage space 2A, a speaker unit 4 accommodated in the storage space 2A, and the speaker The flexible circuit board 5 electrically connected to the monomer 4, the front chamber 6 communicated with the external environment, and the leakage structure 7.

[0029] The upper cover 1 includes a top wall 11 and an upper cover side wall 13 extending from the top wall 11 to a direction away from the top wall 11 , and the number of the upper cover side walls 13 is four, conne...

Embodiment 2

[0043] Please refer to Figure 4 and Figure 5 ,in, Figure 4 It is a three-dimensional assembly diagram of Embodiment 2 of the speaker cabinet provided by the present invention, Figure 5 for Figure 4 A sectional view of the speaker cabinet shown along line A-A.

[0044] The structure of the second embodiment is basically the same as that of the first embodiment. The difference between the speaker box 200 and the speaker box 100 is that the leakage structure 7 is not completely the same.

[0045] Specifically, in the second embodiment, the leakage structure 7 also includes a sealing cover 71 arranged above the upper cover 1 and a leakage pipe 73 opened on the top wall 11, the upper cover 1 and the The sealing cover 71 encloses a cavity 72, and the leakage duct 73 communicates with the front chamber 6 and the cavity 72, and the leakage duct 73 includes a first open end 731 communicating with the cavity 72, and a first opening end 731 communicating with the cavity 72. The...

Abstract

The invention provides a loudspeaker box and an electronic device with the loudspeaker box. The loudspeaker box comprises an upper cover with a top wall, a lower cover, a single loudspeaker contained between the upper cover and the lower cover, and a leakage structure. The single loudspeaker comprises vibration diaphragm. The upper cover and the vibration diaphragm form a front voice chamber. The loudspeaker box is also equipped with a voice outlet channel communicated with the front voice chamber. The front voice chamber and the voice outlet channel form a front chamber. The leakage structure comprises a sealing cover and a leakage pipeline arranged on the top wall. A hollow chamber is enclosed by the upper cover and the sealing cover. The leakage pipeline is communicated with the front chamber and the hollow chamber. The leakage pipeline comprises a first opening end communicated with the hollow chamber, a second opening end communicated with the front chamber, and a connection channel connected with the first opening end and the second opening end. Compared with the prior art, the loudspeaker box provided by the invention has the advantages that the intermediate frequency distortion is relatively low, the high frequency resonance is reduced, the resonance peak is reduced, the high frequency components are reduced, the sense of listening gets better, and there is no voice crosstalk at a voice outlet hole.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a speaker box and electronic equipment with the speaker box. 【Background technique】 [0002] With the advent of the mobile Internet era, the popularity of audio equipment is getting higher and higher. People's requirements for audio equipment are not limited to video and audio playback, but also put forward more requirements for the reliability of audio equipment. Especially with the advent of the 4G era, mobile multimedia technology has also developed. Many audio devices have multiple entertainment functions, such as video playback, digital photography, games, GPS navigation, etc. [0003] In audio equipment, a speaker box is a commonly used electronic component, mainly used for playing audio signals. A speaker box in the prior art includes an upper cover, a lower cover that is assembled with the upper cover to form a storage space, and a speaker unit that is accommo...
