Abstract
The utility model relates to a TV with the function of wireless audio transmission. The TV comprises a TV main chip with a channal selector, an audio power amplification chip and a horn which are connected in sequence and a remote controller. The TV provided by the utility model is characterized in that the channal selector in the TV main chip is connected with a single chip launcher chip by an analog switch so as to form an audio transmitting circuit; a wireless audio receiving circuit is arranged in the remote controller and is connected with a single chip FM radio chip, a potential switch and a resonant circuit of a adjustable frequency in sequence. The TV provided by the utility model has the advantages that interferences from surrounding people can be avoided when a user is watching TV alone and the distance is greatly broadened, people can hear the sound of the TV even if people are a littler far away from the TV. Besides, the function of an FM radio is added to the remote controller and users can also listen to radio programs with the function.
Description
Technical field
The utility model belongs to television set, relates in particular to a kind of television set with ANTENN AUDIO transfer function.
Background technology
The TV of Xiao Shouing substantially all is to transmit voice signal by the machine upper speaker or by the wired earphone that is inserted on the TV in the market.Turn on TV in some occasion and can produce interference,, see TV is crossed closely can impact eyesight though, be subjected to the restriction of earphone lead if plug in the earphone and no longer influence others to the people around.Market demands developing a kind of television set with ANTENN AUDIO transfer function urgently.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of television set with ANTENN AUDIO transfer function is provided, and the user can avoid the interference to the people around when watching TV alone; And the restriction of distance is relaxed greatly, even slightly far also can listen to sound of television from TV.
The utility model for achieving the above object, by the following technical solutions: a kind of television set with ANTENN AUDIO transfer function, comprise and have television set master chip and the remote controller that channel to channel adapter and sound power amplifier chip and loudspeaker connect successively, it is characterized in that: the channel to channel adapter in the described television set master chip connects with the monolithic emitter chip by analog switch and forms the audio frequency radiating circuit, be provided with the ANTENN AUDIO receiving circuit in the described remote controller, described ANTENN AUDIO receiving circuit is connected successively by the resonant circuit of monolithic FM radio chip, level switch and adjustable frequency.
The beneficial effects of the utility model: the user can avoid the interference to the people around when watching TV alone; And the restriction of distance is relaxed greatly, even slightly far also can listen to sound of television from TV.In addition, added the function of FM receiver on the remote controller, the user can also come the broadcast listening program by it.
Description of drawings
Accompanying drawing is emitter and receiving device theory diagram.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in the figure, a kind of television set with ANTENN AUDIO transfer function, comprise and have television set master chip and the remote controller that channel to channel adapter and sound power amplifier chip and loudspeaker connect successively, channel to channel adapter in the described television set master chip connects with the monolithic emitter chip by analog switch and forms the audio frequency radiating circuit, be provided with the ANTENN AUDIO receiving circuit in the described remote controller, described ANTENN AUDIO receiving circuit is connected successively by the resonant circuit of monolithic FM radio chip, level switch and adjustable frequency.Wherein reflector adopts MC2831/MC2833 or other similar replacing chips, wherein the broadcast receiver chip adopts similar sp1088 monolithic electric tuning FM radio machine chip or other alternative chips, chip is different can be changed resonant circuit to some extent according to adopting, and sp1088 is adjustable RC concussion loop.
Operation principle:
(1). radiating portion 1
This part is passed through the way of output of channel to channel adapter guide sound tone signal by the master chip (MICOM) and the software control of television set with the pin (this leg signal is by software control) of MICOM:
If select the loud speaker output of TV, then cut off the power supply of reflector simultaneously by analog switch, pass through the tv speaker output sound behind the voice signal process sound power amplifier;
If select the wireless output of reflector, by the MUTE signal sound power amplifier is quit work when then connecting transmitter power, voice signal through monolithic FM (frequency modulation) transmitter modulation to certain frequency (F0) after launch by antenna.
(2). receiving unit 2
This part places in the remote controller, but and partly separately work of remote control, mainly constitute by monolithic FM radio machine chip and the resonant circuit of controlling its receive frequency, after the S2 energized, the monolithic FM receiver is started working, accept radiofrequency signal by antenna, operating switch S1 selects to receive the voice signal of TV or receives the FM receiver signal.
Pattern 2 receives the voice signal of TVs, makes the frequency of broadcast receiver chip select input to link to each other with the resonant circuit of fixed frequency by switch S 1, and this frequency is decided according to the frequency that the frequency-modulated transmitter of TV transmits, and the sound signal processing mode is the same.
Also can save switch and fixed frequency resonant circuit, select tunable resonance circuit input directly to link to each other with the frequency of broadcast receiver chip, select the frequency of listening to unified resonant circuit.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
