Embodiment
See also shown in Figure 4.Implement the embodiment of the inventive method institute operative installations, comprise be electrically connected the respectively circuit for detecting 621 of plug insertion socket of the voice signal switch 611 of the power switch 32 of control panel 41, wireless transmission module 30 and UART (Universal AsynchronousReceiver/Transmitter, universal asynchronous reception transfer bus), loudspeaker 61 and wired earphone 62 of a microprocessor 40.One source of sound 50 amplifier 51 that is electrically connected, amplifier 51 be electrically connected respectively wireless transmission module 30, voice signal switch 611, circuit for detecting 621 are to provide voice output.Power supply unit 70 power switch 32 that is electrically connected, and provide this to install each assembly required electric power.Wherein this power switch 32, voice signal switch 611 can be respectively and comprise the switch that transistor is formed.
Said apparatus can provide the user to utilize control panel 41 to select to exclusively enjoy pattern or sharing model output sound:
1, when the user selects to exclusively enjoy pattern, whether microprocessor 40 can insert socket via the plug of circuit for detecting 621 detecting wired earphones 62; If when inserting, promptly control power switch 32 non-conducting electric power, make wireless transmission module 30 can't transmit the radio sound carrier signal to wireless transmission module 30; And guide sound tone signal switch 611 disconnects the transmission of sound signals end of transfer voice signals to loudspeaker 61, makes the loudspeaker 61 can't output sound, has only the wired earphone 62 can output sounds.When the plug that detects wired earphone 62 when microprocessor 40 does not insert the information of socket, promptly control power switch 32 conduct power to wireless transmission module 30, make wireless transmission module 30 obtain supply of electric power, transmit the radio sound carrier signals to wireless headset 33 via antenna 31, simultaneously microprocessor 40 is via back coupling interface (for example UART) the detecting wireless earphone 33 of wireless transmission module 30 communication connection whether, when detecting wireless headset 33 when carrying out communication connection smoothly, be that guide sound tone signal switch 611 disconnects transmission of sound signals to loudspeaker 61, have only the wireless headset 33 can output sound; When microprocessor 40 detects wireless headset 33 when failing to carry out communication connection smoothly, promptly guide sound tone signal switch 611 transmission voice signals make loudspeaker 61 output sounds to loudspeaker 61, and loudspeaker 61 output sounds are only arranged this moment.
2, when selecting sharing model, the user can select wired earphone 62, loudspeaker 61, wireless headset 33 three's sharing models via control panel 41 control microprocessor 40, or wherein any both sharing models.When selecting three's sharing model or wireless headset 33, loudspeaker 61 the two sharing model, microprocessor 40 is promptly controlled power switch 32 and is kept the state of conduct power to wireless transmission module 30, and guide sound tone signal switch 611 is kept the state of output sound signal to loudspeaker 61, make wired earphone 62, loudspeaker 61, wireless headset 33 threes output sound simultaneously, or make the two output sound simultaneously of wireless headset 33 and loudspeaker 61.When selecting wireless headset 33 or loudspeaker 61 to share with wired earphone 62 respectively, microprocessor 40 is promptly controlled power switch 32 and is kept the state of conduct power to wireless transmission module 30, or guide sound tone signal switch 611 keeps the transmission voice signal to the state of loudspeaker 61, make wireless headset 33 or loudspeaker 61 respectively with the two output sound simultaneously of wired earphone 62.
See also Fig. 2, Fig. 4, shown in Figure 5.Implementing the specific embodiment of the device of the inventive method, is to make the circuit for detecting 621 of the plug insertion socket of microprocessor 40, power switch 32 and wired earphone 62 among Fig. 4 constitute a control circuit.This control circuit mainly is to make control end shown in Figure 1 13 microprocessor 40 that is electrically connected, (can be the microprocessor of numbering 8051 or 8088), and make an output 131 of microprocessor 40 replace original control end 13 transistor 14 that is electrically connected.Left and right sound output terminal 11,12, loudspeaker 61 and the microprocessor 40 voice signal switch 611 that is electrically connected respectively in addition; Be electrically connected the in addition UART of wireless transmission module 30 of microprocessor 40.
The user utilizes the control panel 41 of microprocessor 40, can select " exclusively enjoying pattern " or " sharing model ".When " exclusively enjoying pattern ", microprocessor 40 makes output 131 have identical high and low potential state with the CN end of earphone socket 20, the operator scheme that its effect is known as described above, when wired earphone inserted earphone socket 20, wireless transmission module 30 promptly can not obtain supply of electric power transmission voice signal; When wired earphone did not insert earphone socket 20, wireless transmission module 30 can obtain supply of electric power, the transmission voice signal.
When " sharing model ", no matter the CN of earphone socket 20 end is at high potential or electronegative potential, microprocessor 40 makes output 131 keep high-end trim, makes wireless transmission module 30 all can obtain supply of electric power, by antenna 31 transmission wireless voice carrier signals.Therefore the user can receive voice signal via wireless headset and wired earphone simultaneously, reaches and shares the function of listening to sound.
See also shown in Figure 6.Method of the present invention comprises the steps:
61 make the microprocessor detecting whether the set information of model selection be arranged;
62 when the set information of " exclusively enjoying pattern ", microprocessor is promptly controlled power switch, the ability output power is not to the wireless transmission module when earphone socket inserts headset plug, make wireless transmission module transmission radio sound carrier signal, and guide sound tone signal input switch disconnects voice signal to loudspeaker, unless detect wireless headset when failing to carry out communication connection smoothly via the back coupling interface of wireless transmission module at the wireless transmission module, just guide sound tone signal switch transmission voice signal makes the loudspeaker output sound to loudspeaker;
63 when the information of " sharing model ", microprocessor is promptly controlled power switch, output power is to the wireless transmission module, make wireless transmission module transmission voice signal, and/or guide sound tone signal switch, the transmission voice signal even this back coupling interface detects wireless headset can carry out communication connection information smoothly the time, also makes the loudspeaker output sound to loudspeaker.
Microprocessor of the present invention is the microprocessor that has of voice output itself also, only will make microprocessor cooperate the control circuit of identical function, can reach the function of selecting " sharing model " or " exclusively enjoying pattern " for the user.Utilize the earpiece holes socket, the action that the detecting plug inserts, the automatic switchover radio device carries out the device connecting method, exempts manually operated inconvenience.Can allow the online and wired earphone of wireless headset also be driven again according to need, allow a player allow two people share simultaneously, or allow loudspeaker play sound simultaneously, make voice output have more diversified sound output function, promote competitiveness of product with wireless headset and wired earphone support.
The above record only for utilizing the embodiment of the technology of the present invention content, anyly is familiar with modification, the variation that this skill person uses the present invention to do, and all belongs to the claim that the present invention advocates, and is not limited to the content that embodiment discloses.
