Abstract
The utility model relates to a driver of an alarm for vehicles and domestic use, which can be widely installed on various vehicles, alarms used in families in a matching mode and horns. The driver is formed by that a vibrating diaphragm provided with a pressing edge and a connecting plate are fixed to a bracket and the connecting plate is connected with a PC plate provided with a driving circuit. A piezoelectric piece connected with the connecting plate through an outgoing line is also fixed to the vibrating diaphragm. The vibration of the piezoelectric piece is adopted to drive the vibrating diaphragm to vibrate and sound so as to replace traditional magnetic materials, such as magnetic steel, etc., to generate a magnetic field for enabling a voice coil which is electrified to move and sound in the magnetic field. The utility model has the advantages of simple structure, few parts, easy assembly, light weight, small size, low cost, good energy saving effect and good sound quality. The current of the utility model is small and is 1/2 to 1/3 of the original current.
Description
The utility model relates to the vitals in a kind of annunciator---sounding body, can extensively be installed on the various vehicles and family on the used annunciator, matching used automobile-used, household alarm actuator also can be widely used on the bugle with it.
The sounding body of existing annunciator is a loud horn, by magnetic material production magnetic fields such as T iron, magnet steel, washers, after the voice coil loudspeaker voice coil energising, in magnetic field, move and sound, thereby reach sounding effect, because of including parts such as magnet steel, part is many, deal is heavy, volume is big, electric current is big, cost is high.And piezo can only produce high frequency, can not produce low frequency, and frequency range is less.
The purpose of this utility model is to provide a kind of automobile-used, household alarm actuator, and few, the easy assembling of its part, volume is little, cost is low and electric current is little, tonequality is good.
The utility model is to realize like this.Automobile-used, household alarm actuator are fixed on the support by vibrating diaphragm and the touch block of being with flanging, and connect and compose by touch block and PC plate; Also be fixed with on the described vibrating diaphragm by pig-tail wire and touch block bonded assembly piezoelectric patches, have by diode D on the PC plate

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Support (4) has uniform four fan-shaped through hole for the centre exceeds, and also is fixedly connected with the round platform of touch block (2) at a fan-shaped pylone place, and the bottom surface is a square, respectively has a projection, centre that the plum blossom jump ring (8) of through hole is arranged on four jiaos.
Vibrating diaphragm (5) and support (4) shape are complementary, and have on the edge upwards, the film of annular groove downwards.
Flanging (7) is for to be made into by elastomeric material, the annulus that the cross section is rectangular.
Piezoelectric patches (6) with two pig-tail wires (3), fasten with glue on the center of vibrating diaphragm (5) lower surface, and vibrating diaphragm (5) fastens with glue in support (4) round platform lower edge groove, flanging (7) is pasted again and is bonded on the edge of vibrating diaphragm (5), touch block (2) is connected with the PC plate (1) that driver circuit is installed by lead, constitute automobile-used, the household alarm actuator, again PC plate (1) is fixed in the caulking groove on the housing sidewall, and support (4) directly is fixed on the fixed leg of housing by the plum blossom jump ring (8) on it, and the wooden handcart that closes the lid is used, household alarm is assembled into (housing, cover plate figure omits).

During use, press button with the connection lead on the PC plate (1), connect 12 volts of DC current, voltage is added on the two ends of piezoelectric patches (6) by PC plate (1), touch block (2), and driving piezoelectric patches (6) work makes its vibration, vibrate, sound thereby drive the vibrating diaphragm (5) that links together with it, and make sound become big, thereby reach the purpose of warning.
The utility model is compared with prior art: drive piezoelectricity because the alarm driver has adopted by driver circuit Sheet, namely making alive on piezoelectric patches makes the piezoelectric patches vibration, drives the vibrating diaphragm that links together with it and shakes The structure of moving sounding has replaced traditionally with magnetic material production magnetic fields such as magnet steel, makes energized coils in magnetic field In the structure of motion sounding, so simple in structure, part is few, easy assembling, volume are little, weight saving, one-tenth This is low. Simultaneously required electric current is little, only have original 1/2～1/3, good energy-conserving effect, and working long hours not Fever phenomenon can take place, and tonequality is good, stay in grade.
