Abstract
The utility model is suitable for the field of sounders, and provides a sounder realizing surround sound and super bass wireless transmission. The sounder includes a power amplifier host machine, a left sound box, a right sound box, a super bass sound box and a surround sound box, wherein a wireless emitting module is arranged in the power amplifier host machine, a wireless receiving module is arranged in the super bass sound box, and the wireless connection is built between the super bass sound box and the power amplifier host machine. In the utility model, three paths of singles of surround sound and super bass share one wireless module to realize corresponding transmission, and a bass sound box and the surround sound box are arranged at the rear part to solve the problem in installation; in consideration of the requirement of comprehensive cost, the bass sound box is provided with all circuits having the functions inside; the wired connection is adopted between the super bass sound box and the surround sound box; and the placement of the bass sound box is not limited, so that the connection of the bass sound box and the surround sound box can be realized in the shortest distance, and conveniences are brought to the installation.
Description
Technical field
The utility model relates to the sound technique field, relate in particular to a kind of realize around with the sound equipment of subwoofer wireless transmission.
Background technology
In small-sized 5.1 ambiophonic systems at present panel TV, owing to need the amplifier and the audio amplifier of 6 sound channels at least, system connects and installs all relatively complicated.As shown in Figure 1, in tradition 5.1 ambiophonic systems, generally main amplifier is placed on the place ahead, consider the high-fidelity requirement of main sound box simultaneously, 3 groups of audio amplifiers (left, center, right) in main amplifier and the place ahead all pass through wired connection, the position forwardly because above-mentioned main power amplifier and audio amplifier exist together, corresponding installation connection becomes easy.But the situation of the audio amplifier of surround channel and subwoofer audio amplifier is just different, and surround speaker is because the position is in the back upper place, and generally all volume is bigger for woofer, and with traditional wired connection, it is put and connects up will be much more difficult.
Along with the wireless transmission technology development, existing, with surround speaker and subwoofer audio amplifier transmission of wireless signals, as shown in Figure 2.But surround speaker and woofer have 3 passages, will use 2 groups of wireless module at least, and the problem of bringing is exactly 1) the cost height; 2) stability problem that causes of phase mutual interference; 3) system is to the initial reset problem of a plurality of modules.
The utility model content
The purpose of this utility model be to provide a kind of realize around with the sound equipment of subwoofer wireless transmission.
The utility model embodiment realizes like this, a kind of realize around with the sound equipment of subwoofer wireless transmission, comprise: power amplifier main frame, left voice box, right voice box, subwoofer audio amplifier and surround speaker, be provided with wireless transmitter module in the described power amplifier main frame, be provided with wireless receiving module in the subwoofer audio amplifier, subwoofer audio amplifier and power amplifier main frame are set up wireless connections.
Wherein, adopt wired connection between described surround speaker and the subwoofer audio amplifier.
Wherein, described surround speaker comprises: left surround speaker and right surround speaker.
Wherein, described left voice box and right voice box are set up wired connection with the power amplifier main frame respectively.
Wherein, also comprise center-channel speaker, described center-channel speaker and power amplifier main frame are set up wired connection.
The utility model embodiment compared with prior art, beneficial effect is: the utility model by will around with subwoofer 3 road signals with a wireless module, realize corresponding transmission, woofer and surround speaker are placed on the problem that the rear position has solved the installation aspect; Consider the requirement of integrated cost simultaneously, whole circuit of above-mentioned functions are contained in woofer inside, take wired connection between subwoofer audio amplifier and the surround speaker, because woofer is not put restriction, be connected and bring the convenience of installing so can realize the beeline of woofer and surround speaker.
