[embodiment]
Below will combine as figure, the specific embodiment of the utility model will be done further detailed description.
As shown in Figure 1; A kind of specific embodiment of microphone; Comprise microprocessor, detection signal transmitter unit and detection signal receiving element; Said microprocessor is connected with said detection signal transmitter unit to send detection signal, and said microprocessor is connected the detection signal that returns with reception with the detection signal receiving element, and said microprocessor is used for basis and has or not and receive the detection signal that returns with the processing to audio frequency of unlatching or mute microphone (MIC).Microprocessor transmits control signal through giving the detection signal transmitter unit; The detection signal transmitter unit is promptly launched detection signal, and detection signal runs into barrier and returns, and is received by the detection signal receiving element; The signal that microprocessor promptly can obtain from the detection signal receiving element; Promptly can judge within the reconnaissance range of detection signal, have the people of barrier or speech, then control microphone and open processing audio frequency; If the detection signal receiving element is not received corresponding inverse signal, microprocessor then microphone cuts out the processing to audio frequency.
As shown in Figure 2; Among a kind of more concrete embodiment of microphone; The pickup unit of said microphone is connected with the audio signal transmission unit, and pickup unit converts the signal of telecommunication in order to accomplish sound into by mechanical signal, perhaps can also comprise the functions such as amplification filtering to the signal of telecommunication.When the detection signal receiving element does not receive the detection signal that returns; Pickup unit is closed in microprocessor control, stops the reception to the wave audio signal, for example cuts off the power supply to the acoustical-electrical transducer spare of pickup unit; Promptly closed the function of the reception sound of microphone; When the detection signal receiving element received inverse signal, pickup unit was opened in microprocessor control, had promptly opened the function of microphone reception sound.
As shown in Figure 3; The another kind of embodiment of microphone, microphone also comprises the audio signal transmission unit, pickup unit is connected with the audio signal transmission unit; Be used for and from the audio signal of pickup unit output after ovennodulation, transmit through wireless or wired mode.When the detection signal receiving element does not receive the detection signal that returns; The audio signal transmission unit is closed in microprocessor control; Though thereby microphone ability received audio signal; But audio signal is not transmitted, thereby be equivalent to close the function that microphone receives sound yet, when the detection signal receiving element receives the detection signal that returns; The audio signal transmission unit is opened in microprocessor control, and the audio signal that microphone receives promptly can forward again and play through corresponding loud speaker.
As shown in Figure 4, the another kind of embodiment of microphone, microphone also comprises audio treatment unit; Pickup unit is connected with audio treatment unit, and audio treatment unit is connected with the audio signal transmission unit of microphone, and audio treatment unit is to carrying out signal processing from the audio signal of pickup unit output; To improve sound quality or other functions; When the detection signal receiving element received the detection signal that returns, audio treatment unit was opened in microprocessor control, otherwise closes audio treatment unit; Make the audio signal transmission unit not have input signal and can't send, thereby the essence mute microphone (MIC) receives the function of sound.
As shown in Figure 5; The another kind of embodiment of microphone; Microphone also comprises the voltage-regulation unit; Power supply is connected and supply power voltage with the detection signal transmitter unit through said voltage-regulation unit, and when microprocessor detected the supply voltage reduction, microprocessor control voltage-regulation unit was to raise to the supply power voltage of detection signal transmitter unit.Because the detection range of detection signal transmitter unit directly is associated with supply power voltage, therefore pass through the stable of the accurate controller supply power voltage of microprocessor, guaranteed the accurate and stable of detection range.
As shown in Figure 6; The another kind of embodiment of microphone, microphone also comprises the duty cycle adjustment unit, said microprocessor is connected with the duty cycle adjustment unit to regulate output duty cycle; Power supply is connected with said detection signal transmitter unit with power supply through said duty cycle adjustment unit; When microprocessor detected the supply voltage reduction, control duty cycle adjustment unit was to improve output duty cycle, like this; The supply power voltage of detection signal transmitter unit has promptly raise, and has guaranteed the stable and accurate of detection range equally.
Preferably; Said detection signal transmitter unit is infrared emission unit or ultrasonic transmitting element; Correspondingly, said detection signal receiving element is infrared receiver or ultrasonic wave receiving element, and infrared or ultrasonic emitting receiving circuit is that those skilled in the art are according to prior art knowledge; The technical scheme that can implement no longer elaborates at this.
As shown in Figure 7, preferably, said microphone is provided with the signalling channel that transmits and receives for signal; Said signalling channel comprises signal transmission channel and signal receive path, and said detection signal transmitter unit is arranged in the passage 1 that transmits, and said detection signal receiving element is arranged on and receives in the signalling channel 2 (in fact; Transmission channel and receive path can be changed each other, as long as corresponding transmit and receive the corresponding adjustment in unit, do not influence the enforcement of the specific embodiment of the utility model); Further like this controlled the angle that detectable signal transmits and receives; Thereby, only to survey to people or barrier on the specific direction, this technical scheme is specially adapted to work as this microphone applications on microphone holder; The people need not to take microphone and before microphone, talks; Have only the people to come into the corresponding zone of signalling channel of microphone, the detection signal receiving element just can receive the signal that reflects, and then microphone is opened in microprocessor control.
In order to improve the accuracy of detection; Microprocessor is through the signal of detection signal transmitter unit emission certain width; Like pulse signal of certain width etc., when the detection signal transmitter unit received the signal that returns, microprocessor was measured (through means such as timers) to the width of this pulse signal; Have only with the transmission deration of signal to equate that perhaps close signal just is considered to the corresponding detection signal that returns, otherwise microprocessor does not carry out corresponding action.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.Those of ordinary skill for technical field under the utility model; Under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; And performance or purposes are identical, all should be regarded as belonging to the scope of patent protection that the utility model is confirmed by claims of being submitted to.
