Description of drawings
Fig. 1 is the structural representation of an embodiment sound intermediate frequency of the utility model Play System;
Fig. 2 is the structural representation of wireless acoustics among embodiment of the utility model.
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
In one of the utility model concrete embodiment, portable terminal and wireless acoustics be not through wired connection, but directly mutual through wireless signal, the two has formed an audio frequency broadcast system portable terminal and wireless acoustics.Wherein, said portable terminal can be various portable sets such as mobile phone, PDA, portable computer, panel computer (like all kinds of PAD products such as iPad), individual intelligent television, mobile TV, handheld game terminal, carry-on audio and video terminal.In the embodiment of the utility model, as shown in Figure 1, portable terminal is mainly used in to wireless acoustics audio signal to be play is provided, and said portable terminal comprises memory cell, audio treatment unit and wireless transmit/receive units.The user duplicates audio file through network download or from other equipment and is saved in the memory cell when using portable terminal, when needs are play, selects audio file to be play to offer audio treatment unit; Audio treatment unit carries out corresponding encoding and decoding processing according to the form of audio file, and converts the audio file of digital form the signal output of simulation into; Subsequently through wireless transmit/receive units will be to be play audio signal send to wireless acoustics and play.In the present embodiment, portable terminal to wireless acoustics send be conversion after simulated audio signal (signal that is equivalent to earphone jack output); In another embodiment, portable terminal also can directly send digital audio and video signals to wireless acoustics, by the device of wireless acoustics self digital signal is changed; Said digital audio and video signals can also be the original audio file without decoding, the encoding and decoding of audio file is handled also can be accomplished by wireless acoustics.
Particularly, as shown in Figure 2 in the embodiment of the utility model, wireless acoustics comprises wireless transmitter, apparatus for processing audio and audio playing apparatus.Wireless acoustics carries out alternately through wireless transmitter and exterior terminal (like above-mentioned portable terminal), receives the audio signal to be play that exterior terminal is sent, and sends to audio playing apparatus after the audio signal of treating broadcast is handled and carries out voice playing.
Wherein, wireless transmitter receives the control signal and audio signal to be play of exterior terminal through the identification signal and the feedback information of wireless transmission unit to exterior terminal transmission wireless acoustics through radio receiving unit.Particularly; Externally the terminal is through the starting stage of wireless acoustics audio plays; Exterior terminal search associated wireless devices; Wireless acoustics receives after the search signal identification signal of sending self to exterior terminal, and exterior terminal selects control corresponding mode and wireless acoustics to connect according to this identification signal, and wireless acoustics is received and set up or break off and return the feedback information confirming or refuse behind the connection request (in principle; A wireless acoustics is merely an exterior terminal and provides support at one time, thereby possibly have the situation of refusal terminal connection request; Under the situation that does not have conflict, wireless acoustics accept request set up or break off connect and return confirmation).After connecting, wireless acoustics receives audio signal to be play from exterior terminal and plays.
As described before, the signal that send at the terminal also can be digital audio and video signals or undressed audio file, thereby the apparatus for processing audio of wireless acoustics comprises memory, processor and digital to analog converter.Processor is at first judged the audio signal to be play that receives, if be simulated audio signal, then directly offer audio playing apparatus and plays; If what receive is not simulated audio signal, memory is stored it and in processing procedure subsequently, is offered processor.Processor judges once more whether signal has passed through decoding processing, handles and offers D/A conversion unit again if then carry out encoding and decoding according to the form of signal sound intermediate frequency file through decoding processing; If pass through decoding processing, then directly offer D/A conversion unit.The digital audio and video signals that D/A conversion unit will pass through decoding processing converts analog output signal into.
In audio playing apparatus, comprise audio power amplifier unit and loudspeaker unit again, audio power amplifier unit carries out power amplification to analog output signal, and the hi-fi effect when guaranteeing voice playing is play the audio signal after the power amplification by loudspeaker unit subsequently.
In the specific embodiment of the utility model, the wireless interaction between wireless acoustics and the exterior terminal can adopt multiple modes such as bluetooth, infrared, RF, FM or hyperfrequency to carry out.Loudspeaker unit can be simple loudspeaker; Also can form stereo playing system by a plurality of loudspeaker; Even can adopt multiple different loudspeaker to come to play respectively the audio signal of low frequency, intermediate frequency and/or high frequency, appreciate demand to satisfy the different audio frequency and video of user.Wireless acoustics can also carry out the remote control of volume and/or result of broadcast through wireless remote controller except selecting for use audio preferably the high-fidelity music center; Certainly, also can directly adopt exterior terminal that wireless acoustics is carried out remote control.
By the way; For providing a kind of audio frequency and video of more flexible high-quality, portable terminal appreciates mode among the embodiment of the utility model; Make the user when private occasion is used portable terminal; Can break away from the restriction of number, body sense and the audio of earphone broadcast, also needn't receive the position limit of wired connection, under the situation that obtains the high quality audio result of broadcast, guarantee the flexibility of portable terminal.
Above execution mode only is used to explain the utility model; And be not the restriction to the utility model; The those of ordinary skill in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to the category of the utility model, and the real protection scope of the utility model should be defined by the claims.
