Abstract
The utility model relates to a multi-purpose electronic vibration-controlled switch for monitoring vibration. The multi-purpose electronic vibration-controlled switch uses a piezoelectric sheet as a vibration sensor. When the multi-purpose electronic vibration-controlled switch is used for controlling vocal vibration, the piezoelectric piece is placed in a vocal assisting cavity; when the multi-purpose electronic vibration-controlled switch is used for controlling solid vibration, the piezoelectric piece is pasted on a measured solid. The piezoelectric piece controls a switch circuit to act and gives a switch signal after the piezoelectric piece transforms a vibratory force signal into an electrical signal and the electrical signal is amplified by an amplifying circuit. Consequently, the multi-purpose electronic vibration-controlled switch can be made into a voice-controlled switch or an anti-theft alarm, etc.
Description
The utility model relates to a kind of electronic switching device of monitoring vibration, especially can monitor the multifunctional electronic vibration-controlled switch device of audiogenic air vibration and solid vibration.
At present, known electronics vibration-controlled switch device is made up of vibrating sensor, amplifying circuit and switching circuit.The vibration force signal can amplify and the control switch circuit operation by the vibrating sensor reception and through amplifying circuit.But used vibrating sensor range of application is narrower, is used for the solid vibrating sensing and electret is used for sound sensor etc. more as resistance strain plate more.Thereby make single vibration-controlled switch purposes comparatively single.
The purpose of this utility model provides a kind of multifunctional electronic vibration-controlled switch, and it can not only monitor acoustical vibration also can monitor the solid vibration.
The purpose of this utility model is achieved in that vibrating sensor is a piezoelectric patches, and it is the signal of telecommunication with the vibration force signal transformation that receives and is exaggerated circuit amplification back control switch circuit operation.Shake when control when being used for sound, piezoelectric patches is positioned over to help experiences acoustical vibration in the operatic tunes.Shake when control when being used for solid, piezoelectric patches directly sticks on experiences the solid vibration on the tested solid.Thereby the scope of application of vibration-controlled switch is greatly expanded, but the multipurpose use, as make audio-switch or burglar alarm etc.
Owing to adopt such scheme, can experience acoustical vibration and solid vibration signal with piezoelectric patches, thus the action of control electronic switch.Simple in structure.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is first embodiment structural map of the present utility model.
Fig. 3 is second embodiment structural map of the present utility model.
1. piezoelectric patches among the figure, 2. amplifying circuit, 3. switching circuit 4. helps the operatic tunes, 5. tested solid.
In Fig. 1, vibrating sensing piezoelectric patches (1) links to each other with amplifying circuit (2), links to each other with switching circuit (3) again.
In Fig. 2, vibration-controlled switch is used for monitoring acoustical vibration, helps in the operatic tunes (4) so piezoelectric patches (1) places, and links to each other with amplifying circuit (2), links to each other with switching circuit (3) again.
Among Fig. 3, vibration-controlled switch is used for monitoring the solid vibration, upward and with amplifying circuit (2) links to each other so piezoelectric patches (1) is pasted on tested solid (5), links to each other with switching circuit (3) again.
Claims (3)
1, a kind of multifunctional electronic vibration-controlled switch, vibrating sensor links to each other with amplifying circuit and links to each other with switching circuit, it is characterized in that: vibrating sensor is a piezoelectric patches (1).
2, multifunctional electronic vibration-controlled switch according to claim 1 is characterized in that: piezoelectric patches (1) places and helps in the operatic tunes (4) as the acoustical vibration sensing.
