Abstract
The present invention relates to the Patting type door bell that a kind of vibration signal that produces by beating starts the doorbell sounding, it is made of piezoelectric element, amplifying circuit, trigger, music integrated circuit, another amplifying circuit and sounding component.Piezoelectric element converts vibration signal to electric signal, and input trigger after amplifying, trigger make music integrated circuit work, and exports a music signal, and this signal is through amplifying the rear drive sounding component.This Patting type door bell is installed in an inboard, and does not need common doorbell switch outdoors, thereby can remove the trouble that switch is sought in inconvenience from, but and burglar alarm.
Description
The present invention relates to a kind of doorbell, particularly a kind of by patting the Patting type door bell of the vibration signal startup that produces.
Existing doorbell is a discrete, and promptly power supply or starting switch are contained in outdoors, and sounding component then is contained in indoor, and the visitor is when outdoor Push switch, and indoor sounding component just sends the sound, goes to open the door to remind owner.But this discrete doorbell has two shortcomings, the first, and doorbell switch is less usually, comes very much the guest to be difficult for finding, especially at night; It two is, the discrete doorbell provides the chance whether people is arranged in the detecting chamber to the thief, if pressing behind the doorbell switch nobody promises or opens the door, illustrate in the family unmanned, the thief just can commit a crime calmly, and outdoors if no doorbell switch then can only be found out the indoor people that whether has by knocking at the door, can cause neighbours' vigilance like this, the chance that theft takes place is just few.
The objective of the invention is to provide a kind of and start doorbell by patting the vibration signal that produces, this Patting type door bell not only can be realized the prompt facility of existing discrete doorbell, and can avoid to the thief provides opportunity, because it does not establish the doorbell switch that is contained in usually outdoors.
Above-mentioned purpose of the present invention is achieved in that by piezoelectric element and converts vibration signal to electric signal, this electric signal input trigger after amplifying, the signal of trigger output makes music integrated circuit work, the music signal of being exported is after putting into, drive sounding component, thereby realize from patting process to sounding.
Patting type door bell of the present invention can be contained in an inboard, and when outdoor knocking at the door, indoor doorbell just produces music like this, gives owner with prompting; If there is the thief to commit a crime, the vibration that produces when then committing a crime (as pounding the door or vibration that picking lock causes) can make doorbell start, and therefore this Patting type door bell still is a kind of warning protective device.
Below in conjunction with embodiment and accompanying drawing thereof principle of the present invention, feature and advantage are further described.
Fig. 1 is the electrical schematic diagram of the Patting type door bell of proposition according to the present invention.
As shown in the figure, Patting type door bell of the present invention comprises: piezoelectric element HA, sounding component Y, trigger IC
1, music integrated circuit IC
2, and amplify and to use transistor Q
1And Q
2, piezoelectric element HA will pat the vibration signal that produces and be converted to electric signal, and this electric signal is through triode Q
1After the amplification, input to trigger IC
1With 6 pin, in the present embodiment, IC
1Be 42 input nand gate Schmidt triggers (as 4093 series), trigger IC
1Output pin 1 and 10 be connected to music integrated chip IC
2(model is U
1Trigger end 3L66C3860) makes it work and exports a music signal, and this signal is through triode Q
2After the amplification, drive loudspeaker Y sounding.
Be to improve sensitivity and reliability, preferably this Patting type door bell is contained in an inboard and the common regional corresponding position that knocks at the door when mounted.
It is inboard that sounding component Y and piezoelectric element HA can be contained in be everlasting room and door of owner respectively, in order to avoid owner does not hear doorbell sound when far away apart from the gate.
Claims (1)
- A kind of Patting type door bell comprises: sounding component Y, music integrated circuit IC 2, and amplifying circuit, it is characterized in that also comprising piezoelectric element HA and trigger IC 1, piezoelectric element HA will pat the vibration signal that produces and be converted to electric signal, this electric signal input trigger after amplifying, and the output signal of trigger makes music integrated circuit work, and produces a music signal, amplifies rear drive sounding component sounding through amplifying circuit again.
