Abstract
A vehicle multi-channel stereo system, which is characterized in that the vehicle multi-channel stereo system comprises a computer main frame, a USB or 1394 sound card, a purified power supply or an independent power supply and an automobile stereo system power magnify circuit, wherein the USB or 1394 sound card is connected with the computer main frame, the purified power supply or the independent power supply supplies power to the USB or 1394 sound card, and original sound boxes arranged at two sides and an ultra-thin centrally-mounted sound box arranged at the internal front middle portion of the automobile form a 5.1 channel or a 7.1 channel system. When the ultra-thin centrally-mounted sound box can not be arranged at the internal front middle portion of the automobile, a signal of a centrally-mounted channel can be averagely transmitted to a front left channel and a front right channel, and thereby forming a virtual centrally-mounted sound box. The vehicle multi-channel stereo system is relatively fine in appreciation effect, can provide low-noise and multi-channel stereo effect, and can be adaptable to the assembly of automobile stereo systems with varieties of levels.
Description
Technical field
The utility model belongs to vehicle-mounted sound equipment technical field, is specifically related to a kind of multichannel that has, the vehicle-mounted multichannel audio that cost performance is high.
Background technology
The many employings of existing on-vehicle acoustic apparatus are read the dish mode and are obtained multimedia resource from CD or disk, play by fetch equipment and audio amplifier then, the audio amplifier operated by rotary motion is provided with the position to the visual field and other configuration device installation influence of car body in the left and right sides of car body to avoid audio amplifier.
In addition, present on-vehicle acoustic apparatus mostly is the audio frequency media playback equipment of two-channel, multitone case, appreciates weak effect, is difficult to adapt to the needs of existing development of automobile.
The utility model content
The purpose of this utility model is to provide a kind of preferable vehicle-mounted multichannel audio of effect of appreciating, and it adopts host computer as storage and Play Control main body.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of vehicle-mounted multichannel audio is characterized in that described vehicle-mounted multichannel audio comprises host computer and external USB that is connected with host computer or 1394 sound cards, and an automobile audio power amplifier is connected with external USB or 1394 sound cards after connecting audio amplifier.
Concretely, described vehicle-mounted multichannel audio also comprises a power supply, and described external USB or 1394 sound cards connect power supply, and described power supply is power conditioner or independent current source, and described power supply is external USB or the power supply of 1394 sound cards.
The audio amplifier of establishing in the automobile comprises two 5.1 or 7.1 audio amplifiers that set up separately, and the front middle part of automobile is provided with ultra-thin center-channel speaker.Described host computer is provided with the gauge tap of center-channel speaker, and the signal of center channels sent to two audio amplifiers that set up separately when gauge tap was closed, and formed virtual center-channel speaker.
This vehicle-mounted multichannel audio adopts a plurality of audio amplifiers to play, the ultra-thin center-channel speaker of central mounting structure of original audio amplifier of the both sides of car body and car body, and the result of broadcast of realization multichannel and low noise, Ultrathin speaker is not only attractive in appearance, does not also influence driver's the visual field.Described audio amplifier comprise original audio amplifier of being arranged on both sides and in automobile the ultra-thin center-channel speaker of front middle part setting constitute 5.1 sound channels or 7.1 sound channel systems.When front middle part can't be provided with ultra-thin center-channel speaker in automobile, center channels can be provided with switch and push " nothing ", the signal of center channels will on average send to preceding left and right acoustic channels this moment, in car anterior form one virtual mid-, also can realize the multichannel effect.
The beneficial effects of the utility model are that the appreciation effect of this vehicle-mounted multichannel audio is preferable, and the acoustics of low noise multichannel can be provided, and go for the assembling of the automobile audio of various class.
