Abstract
The utility model discloses a sound control recorder pen, which comprises a main control unit, a power supply, a power supply switch, a storage unit and a horn connected on the main control unit and also comprises a first microphone; the first microphone is connected with a sound pressure determining and comparing unit; and the sound pressure determining and comparing unit is connected on the main control unit through a switch element. According to the utility model, the recorder pen controls the main control unit to be in work state or dormant state by detecting sound pressure value of a sound signal; after the recorder pen receives effective sound signal, the main control unit ends the dormant state to enter the work state; and in the way, electric energy of the power supply of the recorder pen can be saved to the greatest extent.
Description
Technical field
The utility model relates to a kind of recording pen, relates in particular to a kind ofly after receiving ambient sound, starts to the recording pen of duty automatically from dormant state.
Background technology
Recording pen is indispensable instrument in crowds such as reporter, business people and student, but present recording pen generally has only power switch, when needs are recorded, turns on the power switch powered-down switch when End of Tape.In the Recording Process that turns on the power switch with the powered-down switch, the recording that has a period of time is invalid recording, around do not have sound will record yet, can waste the power supply of recording pen like this.
If recording pen can be in dormant state when not receiving voice signal, after receiving voice signal, get into duty again, will practice thrift the electric energy of recording pen greatly, prolong the service time of recording pen.
But, do not have such recording pen now.
Therefore, there is defective in prior art, needs further improvement and develops.
The utility model content
The purpose of the utility model be to provide a kind of can the voice signal around receiving after; The recording pen that will be in dormant state starts to duty; Record when making the effective around voice signal of recording pen; Be not in dormant state when having effective voice signal around, farthest practice thrift the electric energy of recording pen.
The technical scheme of the utility model is following:
The sound control recording pen; Comprise main control unit, power supply, power switch, storage unit; Comprise the loudspeaker that are connected on the said main control unit, wherein, also comprise first microphone; Said first microphone connects acoustic pressure and measures comparing unit, and said acoustic pressure is measured comparing unit and is connected said main control unit through on-off element.
Described sound control recording pen wherein, also comprises second microphone that is connected on the said main control unit.
Described sound control recording pen, wherein, said on-off element is a relay.
Compared with prior art; The utility model provides a kind of sound control recording pen; This recording pen is in running order or dormant state through the sound pressure level control main control unit that detects voice signal; After recording pen received effective voice signal, said main control unit can finish dormant state and get into duty, can farthest practice thrift the electric energy of recording pen power supply.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the utility model sound control recording pen;
Fig. 2 is the structural representation of second embodiment of the utility model sound control recording pen.
Embodiment
Below in conjunction with accompanying drawing, further explain is done in the preferred embodiment of the utility model.
The sound control recording pen 100 that the utility model provides, as shown in Figure 1, comprise main control unit 110, power supply, power switch 120, storage unit 130, comprise the loudspeaker 150 that are connected on the said main control unit 110; The sound control recording pen 100 of the utility model also comprises first microphone 140, and said first microphone 140 connects acoustic pressure and measures comparing unit 170, and said acoustic pressure is measured comparing unit 170 and is connected said main control unit 110 through on-off element 160.
Said first microphone 140 receives voice signal, and said acoustic pressure is measured the sound pressure level that comparing unit 170 detects the voice signal of said first microphone 140 receptions, with sound pressure level with the acoustic pressure threshold ratio.When the sound pressure level of voice signal is lower than the acoustic pressure threshold value, said acoustic pressure is measured comparing unit 170 and is judged that the voice signal that said first microphone 140 receives is invalid voice signal.At this moment; Said on-off element 160 transmits control signal to said main control unit 110; Said main control unit 110 is not accepted the power supply of said power supply, and said main control unit 110 is in dormant state, and the voice signal that said first microphone 140 receives can not store said storage unit 130 into yet.Under dormant state, said main control unit 110 does not receive the power supply of said power supply, with saves energy.
When said sound control recording pen 100 is in dormant state; Said first microphone 140 receives voice signal; The sound pressure level of the voice signal that said first microphone 140 of said acoustic pressure mensuration comparing unit 170 detections receives; Further with the acoustic pressure threshold ratio with sound pressure level, when the sound pressure level of voice signal greater than the acoustic pressure threshold value, said on-off element 160 transmits control signal to said main control unit 110; Said main control unit 110 is accepted the power supply of said power supply, and said main control unit 110 finishes dormant state.
When said sound control recording pen 100 finished dormant state, the voice signal on every side that said first microphone 140 will collect sent to said main control unit 110, and said main control unit 110 arrives said storage unit 130 with the file storage of voice signal.
The utility model thinks that said sound pressure level of working as voice signal is greater than the acoustic pressure threshold value, and the voice signal that said first microphone receives is effective voice signal; Said sound pressure level of working as voice signal is less than the acoustic pressure threshold value, and the voice signal that said first microphone receives is invalid voice signal.
Said sound control recording pen 100 is in dormant state when receiving invalid voice signal, under dormant state, said main control unit 110 does not receive the power supply of said power supply, with saves energy.In the said sound control recording pen 100, the voice signal that said first microphone 140 collects both had been used to detect sound pressure level, can when main control unit 110 is in running order, store said storage unit 130 into again.
Second embodiment of the utility model, as shown in Figure 2, the sound control recording pen 200 of this embodiment can directly connect second microphone 180 on said main control unit 110.When said main control unit 110 was in dormant state, the voice signal that said second microphone 180 receives can't be stored said storage unit 130; When said main control unit 110 was in running order, the voice signal that said second microphone 180 receives stored said storage unit 130 into through said main control unit 110.In said sound control recording pen 200, the voice signal that said first microphone 140 receives can not stored into said storage unit 130 by said main control unit 110.
Said on-off element 160 can be a relay.
The sound control recording pen that the utility model provides; Control main control unit through the sound pressure level of judging the voice signal that first microphone or second microphone collect and be in dormant state or end dormant state; Through the in running order still dormant state of voice signal control main control unit; When effective voice signal, said main control unit work is with the electric energy of maximum saving recording pen like this.
Should be understood that above-mentioned statement to the utility model preferred embodiment is comparatively detailed, can not therefore think the restriction to the utility model scope of patent protection, the scope of patent protection of the utility model should be as the criterion with accompanying claims.
