Loudspeaker box

Abstract

The invention discloses a loudspeaker box and belongs to the technical field of sound systems. The loudspeaker box comprises a box body, wherein a power supply cavity, low pitch cavities and high pitch cavities are formed in the front end face of the box body, wherein a passive radiator and a sackbut are arranged in each low pitch cavity, a full-range horn and a tweeter are arranged in each high pitch cavity, a power amplifying circuit board, a CPU circuit board, an LCD assembly and a touch control board are arranged in the power supply cavity, the LCD assembly, the touch control board and the power amplifying circuit board are all electronically connected with the CPU circuit board, and the passive radiators, the sackbuts, the full-range horns and the tweeters are all electronically connected with the power amplifying circuit board. According to the loudspeaker box, the low pitch of the sackbuts is extended substantially by the passive radiators, the lower pitch effect is better than that of a subwoofer, the size is small while the low pitch effect is good, and the problem of poor low pitch effect caused by small sizes is solved; the sound field sense, the layering sense and the orientation sense are improved due to the sequential arrangement and combination of the passive radiator, the sackbut, the full-range horn and the tweeter, the sound field is wide, and the quality of output sounds is improved.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a sound box. Background technique [0002] The speaker is the terminal of the entire audio system, and its function is to convert audio power into corresponding sound energy and radiate it into the space. It is an extremely important part of the audio system, because it is responsible for the key task of converting electrical signals into acoustic signals for human ears to listen directly to. It has to deal directly with human hearing, which is very sensitive. And it has a strong ability to distinguish the timbre of complex sounds. Since the human ear's subjective experience of sound is the most important criterion for evaluating the sound quality of an audio system, it can be considered that the performance of the speaker plays a key role in the playback quality of an audio system. [0003] At present, speakers include high, medium and low speakers, and the collocation...

Problems solved by technology

The bass effect of the speaker has a lot to do with the size of the speaker. Now many speakers on the market that are compatible with TV sets and computers have very small size requirements, and the bass effect is difficult to show. In order to improve this situation, we can only add a bass However, due to the relatively large volume of the dry subwoofer, it will inevitably affect the installation space and installation effect of the TV and computer.
