Abstract
The utility model discloses a multi-soundtrack encircled sound box, which is provided with a sound box body (2). The utility model is characterized in that the sound box body (2) is divided into a lower layer (5), a middle layer (4) and an upper layer (3), the inner part of the lower layer (5) is provided with a pair of main soundtrack sound boxes (220), (221), the front side of the upper layer (3) is provided with a middle sound box (21), both sides of the middle sound box are respectively provided with encircled stereo sound boxes (230), (231), and the bottom of the sound box body (2) can also be provided with rolling wheels (26) which are convenient to move the sound box body. The device is an integral structure, can generate the encircled stereo effect, overcomes the defects of the prior art, such as inconvenient installation, dispersed sound box, complicated installation and construction, etc.
Description
The utility model relates to electroacoustic device, further is meant the multichannel surround speaker.
The configuration of the surround sound of prior art is shown in Figure 1, system places a center-channel speaker (11) the place ahead or the top of audiovisual combination (10), a pair of main sound channel audio amplifier (120), (121) are placed the left and right sides of audiovisual combination (10) respectively, also place user's left back and right back respectively around three-dimensional audio amplifier (130), (131), and be connected to audiovisual combination (10) with signal transmission line (14) with a pair of; When the user when enjoying this audiovisual entertainment, five audio amplifiers will produce the surround sound effect, the brand-new experience of a kind of audiovisual of confession people.
But, existing surround sound needs adapted space to do a proper arrangement, and to be connected between audiovisual combination and each audio amplifier with signal transmission line, therefore the puzzlement that has construction to be difficult for not only needs know-how personnel operation, and after in a single day installing finishes, five audio amplifiers are put five places respectively, both took up space, also must make or have much ado when mobile, so for certain limitation is arranged on the placement location.
The purpose of this utility model is, designs a kind of multichannel surround speaker, and it is combined by a plurality of audio amplifiers, can produce the surround sound effect, and can overcome prior art great in constructing amount, take up room many, connect defectives such as lead is numerous, mobile difficulty.
The technical solution of the utility model is, it has an audio amplifier main body, and its design feature is, this audio amplifier main body is divided into lower floor, middle level, upper strata, be provided with a pair of main sound channel audio amplifier under described, front, described upper strata is equipped with a center-channel speaker, and the both sides on upper strata respectively are equipped with a surround sound audio amplifier.
Make below in conjunction with accompanying drawing and to further specify.
