Low-amplitude multi-unit loudspeaker box

Abstract

The invention belongs to the technical field of loudspeakers, and particularly relates to a low-amplitude multi-unit loudspeaker box which comprises a bass unit, a treble unit and a shell. One side wall of the shell is in bolted connection with a bass unit and a treble unit; the surface vibration of the shell is scanned by adopting laser scanning technology, to find out an area with non-uniform vibration amplitude on the surface of the shell, and reinforce the local area of the shell; the height difference between the convex points and the concave points on the damper in the bass unit is controlled between 1.6-1.8 MM, the smoothness of the positioning support chip is increased, the amplitude is not limited, the distortion is reduced, the tone quality is improved when the low-amplitude multi-unit loudspeaker box vibrates and sounds, meanwhile, the sounding panel of the high pitch unit is designed into an arc curved surface with the radian of 1.3-1.5. Sound waves emitted by the sound production panel are continuously reflected and superposed in the cavity of the high pitch unit, so that the quality of emitted high-frequency sound is enhanced, and the sound pressure level is also improved.

Description

technical field [0001] The invention belongs to the technical field of loudspeakers, in particular to a low-amplitude multi-unit loudspeaker box. Background technique [0002] At present, the speaker box installed on the smart TV is preferably a speaker box with a power of about 20W according to the size of the user's home. However, the existing speaker box with a power of about 20W has high distortion and low high-frequency sound pressure level. At the same time, the voice recognition of smart TV is affected by the vibration of the shell when the sound is radiated by the speaker box, which affects the recognition of voice pickup and cannot give users a better listening experience. Therefore, the present invention provides a high-fidelity, low-amplitude multi-unit loudspeaker box that can enhance high-frequency response. Contents of the invention [0003] In order to make up for the deficiencies of the prior art and solve the problems described in the background art, the ...
