Embodiment
Please refer to diagram now, displaying wherein is only in order to illustrate preferred embodiment of the present utility model, but not limited to its category.For the utility model notion is passed in those skilled in the art.In the drawings, can be clear and exaggerative each size of component.
Fig. 2 is the circuit block diagram of the radio play system of an embodiment of the present utility model.Please refer to Fig. 2.Radio play system 200 can comprise ANTENN AUDIO playing device 210 and wireless remote controller 230.ANTENN AUDIO playing device 210 can comprise a digital broadcasting chip 218, an amplifier 220 and loudspeaker 222.
This ANTENN AUDIO playing device 210 can be used for playing digital audio broadcasting (Digital Audio Broadcasting abbreviates DAB as).Digital broadcasting chip 218 receives the digital audio broadcast singal DAB_S from digital broadcasting radio station 250, and converts digital audio broadcast singal DAB_S to a stereo high fidelity signal (stereo high fidelity signal) SHF.Amplifier 220 is coupled between digital broadcasting chip 218 and the loudspeaker 222.Amplifier 220 is used for amplifying stereo high fidelity signal SHF and becomes a stereo audio signal Audio_S.Then loudspeaker 222 are play stereo audio signal Audio_S.
For example, demodulation/decompressor 214 in the ANTENN AUDIO playing device 210 can be adjusted broadcast channel according to the signal of communication COM1 from wireless remote controller 230, or sending one according to this adjusts the power that multiplying power that amplifier signal Tune_A adjusts amplifier 220 is come controls playing sound.Signal of communication COM1 can be Bluetooth protocol signal or Wi-Fi protocol signal, but not as limit.
Moreover, because the computing that ANTENN AUDIO playing device 210 can individual processing digital audio broadcast singal DAB_S, can not take the calculation resources of the CPU 234 in the wireless remote controller 230 when therefore playing the music of digital broadcast program.
The content of digital radio broadcasting program can transmit audio frequency, literal, image, binary data or video.Therefore, ANTENN AUDIO playing device 210 is when playing digital broadcast program, can be (for example with the instant character among the digital audio broadcast singal DAB_S or pictorial information, can be instant message, temperature figure, stock trend graph, but not as limit), transmit signal of communication COM2 to radio-frequency (RF) transceiver 232 via radio-frequency (RF) transceiver 212.Screen 238 by wireless remote controller 230 shows instant character or pictorial information again.The screen 238 of wireless remote controller 230 can be play instant message, picture concerned or current events, so the user can learn activity description immediately.Wherein signal of communication COM2 can be Bluetooth protocol signal or Wi-Fi protocol signal, and wireless remote controller 230 can be mobile phone or mobile network apparatus (Mobile Internet Device abbreviates MID as), but not as limit.For example, wireless remote controller 230 can be intelligent mobile phone, personal digital assistant, portable digital multimedia player, panel computer or the e-book with radio communication function.
What deserves to be mentioned is that digital broadcasting chip 218 can comprise a radio-frequency (RF) transceiver 212, one demodulation/decompressor 214 and a stereo digital to analog converter 216.Demodulation/decompressor 214 is coupled between radio-frequency (RF) transceiver 212 and the stereo digital to analog converter 216.The signal of communication COM1 that radio-frequency (RF) transceiver 212 receives from wireless remote controller 230, and transmit signal of communication COM2 to wireless remote controller 230, and convert digital audio broadcast singal DAB_S to an intermediate-freuqncy signal (intermediate frequency signal) IFS.Demodulation/decompressor 214 receiving intermediate frequency signal IFS, and according to the control of wireless remote controller 230 and convert intermediate-freuqncy signal IFS to a digital channel signal DCS.Stereo digital to analog converter 216 converts digital channel signal DCS to stereo high fidelity signal SHF.
In addition, ANTENN AUDIO playing device 210 can also comprise a power supply 224 independently.This power supply 224 is electrically connected to digital broadcasting chip 218 and amplifier 220.Power supply 224 can be rechargeable battery or storage battery.
Fig. 3 A and Fig. 3 B are the schematic diagrames according to the radio play system 200 of the utility model embodiment.Please refer to Fig. 3 A.ANTENN AUDIO playing device 310A can make wireless pattern earphone.The wireless headset of Fig. 3 A can be play stereo audio signal, so the user can feel that stereo sound is more pleasing to the ear; And this wireless headset can carry out two-way communication with wireless bluetooth or Wi-Fi mode and wireless remote controller 330, to transmit the content of digital radio broadcasting program.For example, the screen of wireless remote controller 330 can show the instant character of " This is DAB " or show that weather is the pictorial information or the film of 25 degree Celsius that wherein content displayed is not as limit.In this embodiment, because ANTENN AUDIO playing device 310A and wireless remote controller 330 do not have the connecting line between the stream oriented device, after the user has selected station channel, wireless remote controller 330 directly can be put into pocket, therefore user's activity is comparatively flexible, and does not have the problem that earphone cord twines.
Referring again to Fig. 3 B.Similarly, the toy trumpet of earphone can be replaced as typhon.Therefore, ANTENN AUDIO playing device 310B can make the portable wireless equipment of raising one's voice.Its power supply can be the power supply of external mounted formula, but not as limit.
Though in the foregoing description to ANTENN AUDIO playing device of the present utility model and the possible kenel of radio play system of using it, but the person of ordinary skill in the field should know, each manufacturer or those skilled in the art are after having seen explanation of the present utility model, design for the ANTENN AUDIO playing device is all different, and therefore application of the present utility model is when being not restricted to above-mentioned possible kenel.In other words, as long as ANTENN AUDIO playing device independent process digital audio broadcast singal, and the channel selection that wireless remote controller can be controlled the ANTENN AUDIO playing device with wireless mode has been to have met spiritual place of the present utility model just during with sound.
ANTENN AUDIO playing device of the present utility model can be play the digital radio broadcasting program, and produces stereo audio.The user can pass through easily channel selection or sound control of wireless remote controller (for example, mobile phone, iPad, MID, but not as limit), and can watch the picture of radio station projection.Thus, can be user's offering convenience property of daily life, and can receive real time information effectively.
In sum, the ANTENN AUDIO playing device can have dual track and play digital broadcast program, and better stereo sound quality can be provided, and the existing bluetooth earphone of solution only has monaural shortcoming.
Though the utility model discloses as above with embodiment; right its is not in order to limit the utility model; any person of ordinary skill in the field; in not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, so protection range of the present utility model is as the criterion when looking the claim person of defining.
