A loudspeaker box

Abstract

A loudspeaker box comprises a loudspeaker box body and a loudspeaker. The loudspeaker comprises a magnetic circuit device, a voice coil and a vibrating diaphragm. The magnetic circuit device comprises a main iron, a magnetic steel and an upper splint. One end of the vibrating diaphragm is connected with the loudspeaker box body. The magnetic circuit device is connected and fixed on the loudspeaker box body. Compared with the prior art, the loudspeaker box of the invention avoids the setting of basin rack as the vibrating diaphragm of loudspeaker are directly connected with the loudspeaker box body directly. The side effect caused by resonance vibration of basin rack and reflection is avoided thereby avoiding the sound distortion caused by basin rack. Additionally the work procedure reduction in bulk production is facilitated. Furthermore the loudspeaker box can be minimized under the precondition that a certain power is guaranteed for satisfying the requirement of loudspeaker minimization, such as the narrow loudspeaker which is more suitable for the required configuration of prior LCD TV.

Description

technical field [0001] The invention relates to a sound box, in particular to a sound box without a basin frame for the loudspeaker. Background technique [0002] Speakers such as subwoofer, bass, mid-bass, and full frequency in the prior art need to be installed on the speaker body or the semi-speaker body with the back open during actual use, otherwise, at low frequencies, the sound waves before and after the diaphragm will be short-circuited. Phenomenon, the bass effect will not come out. The sound box of prior art comprises loudspeaker and sound box body, and loudspeaker such as figure 1 As shown, it includes the basin frame 14 and the magnetic circuit device connected as a whole through the basin frame, the voice coil 5 and the diaphragm 7, wherein the magnetic circuit device includes the main iron 1, the magnetic steel 2 and the upper splint 3, and the speaker is connected to the sound box through the basin frame. Body fixed connection. The materials of the above-me...

AI Technical Summary

Problems solved by technology

The disadvantage of the existing sound box is that when the speaker is installed on the sound box body, the frame will inevitably vibrate with the vibration of the diaphragm, and the sound waves on the back of the diaphragm will also be reflected by the frame to react. To the diaphragm, this will inevitably cause sound dyeing and affect the sound quality, especially the iron frame, which is relatively thin and easy to resonate; if an aluminum frame is used, although the resonance can be weakened, the cost is relatively high
