Embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Fig. 1 is the utility model sound equipment inking device and television set speaker, the structural representation of the first embodiment that sub-woofer is connected with integrated sound box, the sound equipment inking device 10 that this embodiment proposes, with television set speaker 20, sub-woofer 30 is connected with integrated sound box 40, sound equipment inking device 10 comprises configuration module 11 and control module 12, the signal input part received audio signal of configuration module 11, the first signal output connecting TV machine loudspeaker 20 of configuration module 11, the secondary signal output of configuration module 11 connects sub-woofer 30, the 3rd signal output part of configuration module 11 is integrally connected formula audio amplifier 40.Wherein, sub-woofer 30 and integrated sound box 40 can be wired audio amplifier or wireless sound box; When sub-woofer 30 and integrated sound box 40 are wired audio amplifier, can be connected with configuration module 11 by Audio Data Line; When sub-woofer 30 and integrated sound box 40 are wireless sound box, can pass through mode and configuration module 11 wireless connections such as radio frequency, bluetooth, wifi.The control end of control module 12 connects the control end of configuration module 11, controls the gating of one or more signal output part in configuration module 11.
When user does not select sub-woofer 30, while not selecting integrated sound box 40 yet, television set acquiescence adopts television set speaker 20 to play sound, now sound equipment inking device is in TV loudspeaker play mode, control module 12 output the first control signals, the first signal output of gating configuration module 11, configuration module 11 output audio signals are to television set speaker 20, other two paths of signals outputs are in blocking state, sub-woofer 30 and integrated sound box 40 are not worked, and television sound only plays back by television set speaker 20.
When user selects sub-woofer 30 to play sound, now sound equipment inking device is in mega bass play mode, control module 12 output the second control signals, the first signal output of gating configuration module 11 and secondary signal output, configuration module 11 difference output audio signals are to television set speaker 20 and sub-woofer 30, the 3rd signal output part of configuration module 11 is in blocking state, integrated sound box 40 is not worked, the HFS of television sound is play by television set speaker 20, and low frequency part is play by sub-woofer 30.
When user selects integrated sound box 40 to play sound, now sound equipment inking device is in one audio amplifier play mode, control module 12 output the 3rd control signals, the 3rd signal output part of gating configuration module 11, control configuration module 11 output audio signals to integrated sound box 40, the first signal output of configuration module 11 and secondary signal output are in blocking state, and television set speaker 20 and sub-woofer 30 are not worked, and television sound only plays back by integrated sound box 40.
In addition, because sub-woofer 30 and integrated sound box 40 are with respect to television set, belong to external audio frequency playback equipment, the secondary signal output of configuration module 11 and the 3rd signal output part are defaulted as normally open, generally block, only have after the second control signal (corresponding to the secondary signal output of configuration module 11) or the 3rd control signal (corresponding to the 3rd signal output part of configuration module 11) arrival, just can switch to connected state.And television set speaker 20 is parts of television set, belong to built-in audio-frequence player device, the first signal output of configuration module 11 is defaulted as normally off, be generally communicated with, therefore, when in TV loudspeaker play mode and mega bass play mode, control module 12 is without carry out the first signal output of gating configuration module 11 by the first control signal or the second control signal; When in one audio amplifier play mode, the 3rd control signal can also be controlled the first signal output blocking-up of configuration module 11 as the mute signal of television set speaker 20, makes television set speaker 20 quiet, avoids affecting the broadcasting of integrated sound box 40.
In sum, sound equipment inking device in the present embodiment can configure television set speaker 20, sub-woofer 30 and integrated sound box 40 simultaneously, three kinds of play mode can be provided, according to different play mode, by the output switching of audio signal to corresponding audio-frequence player device, make the sound system of television set with better function, meet the demand of different user.
As shown in Figure 2, Fig. 2 is the structural representation of the second embodiment of being connected with television set speaker, sub-woofer and integrated sound box of the utility model sound equipment inking device.In order to realize the switching of different play mode, can adopt the mode of the present embodiment to realize automatic switchover.Control module 12 receives the identity code of sub-woofer 30 or integrated sound box 40 outputs by wired or wireless mode.For example, after sub-woofer 30 starts power on, sub-woofer 30 is to control module 12 output identity codes, these identity codes of control module 12 judgement be sub-woofer 30 or integrated sound box 40, after judging the identity code that this identity code is sub-woofer 30, sound equipment inking device is in mega bass play mode, and control module 12 is exported the second control signals.After integrated sound box 40 starts power on, integrated sound box 40 is to control module 12 output identity codes, control module 12 is after judging the identity code that this identity code is integrated sound box 40, sound equipment inking device is in one audio amplifier play mode, and control module 12 is exported the 3rd control signals.If when control module 12 had not both received the identity code of sub-woofer 30, also do not receive the identity code of integrated sound box 40, sound equipment inking device is in TV loudspeaker play mode, and control module 12 acquiescences are exported the first control signals.
The identity code of the external audio frequency playback equipment that the present embodiment receives by 12 pairs of control modules judges, carrys out automatic switch modes, reduces user's operation.In addition, also switching key can be set on television set, or select switching menu by remote controller, by user, be selected the play mode oneself needing.
