Abstract
The utility model relates to an easily assembled door bell which is composed of an outer shell, a power supply, a push-button switch, a sound reproducer. A door bell outdoor part is provided with a transmitting circuit which is composed of a capacitor, an electric inductance and an induction coil. An indoor part is composed of a receiving circuit which is composed of an induction coil. A music integrated block is triggered and started by electric pulse signals received and generated by an induction circuit, and the music integrated block enables the sound reproducer to sent out sound. The utility model has simple structure, and can be installed without drilling holes and arranging wires.
Description
The utility model relates to a kind of sound equipment, specifically is a kind of doorbell.
Common doorbell be by be contained in outdoors pushbutton switch by lead be contained in indoor player and be connected, when the visitor presses pushbutton switch, trigger the doorbell alarm.The shortcoming of this doorbell maximum needs punching wiring exactly, installs very inconveniently, and it is attractive in appearance influence the room, and is particularly outstanding for the doorbell installation that is tending towards timber, plastic door and glass door etc. that high gradation fits up day by day especially.Though the distance type doorbell has solved the problems referred to above that common doorbell exists, because of its volume is big, the cost height is easy to generate and disturbs and difficult the popularization.
It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, and need not the doorbell that punches and connect up and can install.
The scheme that the utility model purpose realizes is: designed doorbell is the same with common doorbell to be made up of indoor and outdoors two parts, comprise shell, battery, pushbutton switch and player etc., it is characterized in that also comprising the electromagnetic field generation circuit of forming by electric capacity or relay, inductance and inductive coil or pole piece that the electromagnetic field receiving circuit that is made of inductive coil or pole piece is accordingly arranged at the doorbell indoor section at the doorbell outdoor section.When closing doorbell outdoor section pushbutton switch, battery makes inductive coil or pole piece obtain an electric pulse by electric capacity and inductance, sends electromagnetic field pulse by this inductive coil or pole piece again and makes the induction receiving coil of doorbell indoor section or pole piece generation electric impulse signal triggering startup music-integrating block that player is sounded.
For making the utility model doorbell easy for installation, be to have the self-adhesion film in the bottom surface of doorbell shell.
The utility model is simple in structure, only needs indoor and outdoor two parts of doorbell are got final product the inside and outside both sides that are attached to door or wall along the self-adhesion film.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the circuit diagram of an embodiment of the utility model.
Fig. 2 is the utility model doorbell scheme of installation.
The battery E of doorbell outdoor section circuit among the figure
1-the utmost point connects button switch K, and the other end series connection of button switch K is connected to capacitor C
1, inductance L
1With inductive coil L
2, inductive coil L
2The other end take back battery E again
1Another utmost point, at battery E
1And be connected to one between the button switch K and be used for capacitor C
1The lead of discharge.Inductive coil L in the doorbell indoor section electromagnetic field receiving circuit
3An end link to each other L with the common port of music integrated circuit IC
3The other end inserts capacitor C
2A utmost point, C
2Another utmost point connect the input end of IC, IC again with loudspeaker and battery E
2Connect.An adhesive sheet 3,4 respectively is equipped with in the outdoor section shell 1 of doorbell and the bottom surface of indoor section shell 2, when installing and using, along adhesive sheet to be attached to the door 5 on.
Another embodiment of the utility model is with reference to Fig. 1 circuit diagram, with capacitor C
1Displacement relay or with inductive coil L
2And L
3Be replaced as pole piece.
