Novel wireless-surrounded sound box

Abstract

The invention discloses a novel wireless-surrounded sound box, and relates to the technical field of sound boxes. A phase-reversing tube of the sound box is arranged on the upper end surface of a front shell; a bass unit is arranged on the upper side of the middle of the front shell; a treble unit is arranged at the lower end of the bass unit; alto units are symmetrically arranged on two sides of the front shell; a code matching switch, a power indicating lamp and a single-pole / double-pole changing switch are respectively arranged on two sides of the treble unit; a signal input absence automatic power failure circuit and a 2.4G wireless receiver are respectively arranged on two sides of the bass unit; and an annular transformer is arranged at the rear end of the bass unit. The novel wireless-surrounded sound box is a wall-mounted surround box body with 2.4G active power emitting and receiving functions and is suitable for various environments; and due to the design of freely switching a single-pole manner to a two-pole manner, the problem about over-5.1 system configuration of family cinemas is solved effectively.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a novel wireless surround sound box. [0002] Background technique [0003] 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. [0004] At present, there are various speakers on the mar...

AI Technical Summary

Problems solved by technology

[0004] At present, there are various speakers on the market, but most speaker products have certain problems, such as: the applicable environment is limited, and the speaker needs to be selected according to the size of the space; the function is single, and there is only one working mode; the speaker shell resonates Very serious, the shell itself will produce sound when the speaker is working, which will affect the effect of the speaker; the sound is easily distorted, affecting the sound effect and sound quality; the speaker is easily disturbed when it is working
