Abstract
Through a wireless bass sound system, a sound signal in electronic equipment makes a sound. The wireless bass sound system includes sound effect processor, wireless transmission module, and sound output device. Based on receiving sound signal, sound effect processor outputs bass sound signal. Wireless transmission module outputs bass sound signal in wireless transmission mode. Sound output device includes bass loudspeaker, wireless receiving module, and amplifier. The wireless receiving module is in use for receiving bass sound signal in wireless transmission mode. Receiving bass sound signal output from the wireless receiving module, the amplifier drives the bass loudspeaker to make a sound.
Description
[technical field]
The invention relates to a kind of wireless supper bass sound system, and particularly relevant for a kind of wireless supper bass sound system of electronic installation.
[background technology]
Two loud speakers were play stereo about traditional tv only had usually.But because built-in loud speaker on the TV, effect for bass sound signal in handling is not fine, so the bass part of the acoustic signal of traditional tv output all can be filtered out by the sound effect processor in the TV earlier so that about the sound that sends of two loud speakers noise that do not have a too many low frequency occur.
So, based on this design down, when TV station sends out the program of gamut or plays film, stereo via what traditional tv played out, just the part that does not have bass, so when the user viewed and admired the program with supper bass, for example the engine sound in the film just can't be enjoyed the shock of supper bass.Therefore, often the user must spend in addition and purchase a cover sound system, just can have the effect of supper bass.And the sound system of purchasing and coming also needs to dispose many sound source wire, and the length of these a little source of sound distributions may need certain-length, makes whole sound system become very complicated and also may hamper user's current environment.But for only wanting to buy the user that the platform TV just can be enjoyed the supper bass effect, this not only gets budget increase, has more brought user's inconvenience in the use.
[summary of the invention]
In view of this, purpose of the present invention is exactly that a kind of wireless supper bass sound system of electronic installation is being provided, use and solve conventional television and do not have an effect of supper bass, and pass through wireless transmission method, the bass acoustic signal is sent on the woofer, makes the putting position of wireless woofer more flexible.
According to purpose of the present invention, a kind of wireless bass audio-system of electronic installation is proposed.Electronic installation is video-audio playing system for example.Video-audio playing system comprises audio-visual broadcast main frame and voice output.Voice signal is sounded by wireless bass audio-system one of in the video-audio playing system.Wireless bass audio-system includes sound effect processor, wireless delivery module and above-mentioned voice output.Sound effect processor, wireless delivery module system are disposed in the audio-visual broadcast main frame.Voice output system comprises a woofer SP, wireless receiving module and amplifier 212 at least.
Sound effect processor receives voice signal, and exports the bass acoustic signal according to this.Wireless delivery module is exported the bass acoustic signal with the bass acoustic signal with Wireless transmission mode.Wireless receiving module system receives the bass acoustic signal in order to Wireless transmission mode.Amplifier is in order to receiving the bass acoustic signal that wireless receiving module is exported, and drives woofer according to this and sound.
[description of drawings]
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below:
Fig. 1 is the schematic diagram of the electronic installation of preferred embodiment of the present invention.
Fig. 2 is the calcspar of wireless bass audio-system of the electronic installation 100 of Fig. 1.
[embodiment]
The invention provides a kind of wireless bass audio-system of electronic installation, the bass acoustic signal is sent to the voice output of wireless bass audio-system with Wireless transmission mode, make the voice output putting position more flexible, the inconvenience that is caused when sound source wire being set with minimizing.
Please refer to Fig. 1, it is the schematic diagram of the electronic installation of preferred embodiment of the present invention.Electronic installation 100 for example is a video-audio playing system.Video-audio playing system 100 comprises audio-visual broadcast main frame 104 and voice output 108.Audio-visual broadcast main frame 104 for example is television set or computer system, and Fig. 1 system is that example illustrates it with the television set.Television set comprises LCD TV, plasma television or cathode ray tube (Cathode Ray Tube, CRT) TV, and computer system has comprised desktop PC, mobile computer or Barebone.Be not specially limited the kenel of audio-visual broadcast main frame 104 in embodiments of the present invention.Voice output 108 is to carry out the signal transmission with Wireless transmission mode and audio-visual broadcast main frame 104.
Please refer to Fig. 2, it illustrates the calcspar of wireless bass audio-system of the electronic installation 100 of Fig. 1.Wireless bass audio-system 200 includes sound effect processor 204, wireless delivery module 206 and above-mentioned voice output 108.Sound effect processor 204, wireless delivery module 206 are to be disposed in the audio-visual broadcast main frame 104.Voice output 108 is to comprise a woofer SP, wireless receiving module 210 and amplifier 212 at least.
When audio-visual broadcast main frame 104 is television set, video-audio signal VS, it for example is the video-audio signal of wireless or wired TV programme, DVD, VCD film, after sound effect processor 204 processing, sound effect processor 204 output frequencies are higher than L channel acoustic signal L, the R channel acoustic signal R of 180Hz and the bass acoustic signal SS that frequency is lower than 180Hz.Sound effect processor 204 for example is to utilize high pass filter and low pass filter or equalizer to divide occur frequently left and right sound channels acoustic signal L, the R of high frequency and the bass acoustic signal SS of low frequency.Left and right sound channels acoustic signal L, R see through television set about two loud speakers ( loud speaker 114 and 116 that Fig. 1 painted) output sound.And sound effect processor 204 is to export bass acoustic signal SS to wireless delivery module 206.
So, use the television set of wireless bass audio-system of the present invention can have the function of playing the supper bass acoustic signal, and must additionally not buy expensive sound system.And by wireless transmission, can make that more the putting position of voice output 108 is more flexible, the user can be furnished with the personal like, and can not be subject to the length of sound source wire.Person very, because the wireless bass audio-system of electronic installation of the present invention does not need to use sound source wire, the user does not cost the allocation problem of the processing sound source wire of the heart, makes home environment more beautiful and comfortable.
In sum; though the present invention discloses as above with a preferred embodiment; right its is not in order to limit the present invention; anyly have the knack of this skill person; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
