Abstract
The utility model discloses a new type integrated style electric bicycle anti-theft warner buzzing device, comprising a fixing buzzing sheet plastic ring and a piezoelectric ceramic buzzing sheet and a buzzing groove. The piezoelectric ceramic buzzing sheet of the utility model is larger than the piezoelectric ceramic buzzing sheet of the old type integrated style electric bicycle anti-theft warner buzzing device, and a thin plastic sheet is stuck on the back of the piezoelectric ceramic buzzing sheet with special glue, the buzzing groove of the piezoelectric ceramic buzzing sheet is largened, with a larger buzzing space. Buzzing holes of Phi 8 mm to Phi 12 mm and the Phi 50 plastic sheet are reinforced as a buzzing source, the piezoelectric ceramic buzzing sheet is stuck on the plastic sheet of Phi 40 to Phi 55 and the buzzing groove of Phi 40 to Phi 55, and two power wires are externally connected on the Phi 35 piezoelectric ceramic buzzing sheet to the circuit board of the anti-theft device. When being used, electric current is transferred to the piezoelectric ceramic buzzing sheet through the circuit board, causing vibrating and buzzing, and performing the anti-theft function. After improvement, the buzzing is stentorian, and the volume is high.
Description
Technical field
The utility model relates to integral electric car burglar alarm pronunciation device.
Background technology
Old money integral electric car burglar alarm pronunciation device is less because of the volume of annunciator own, can't and vacate big space with big piezoceramic piezo and do the sound groove, maker adopts the piezoceramic piezo of small dimension always, the sender design is less than normal, as Fig. 1, the specification of piezoceramic piezo is 27mm * 0.6mm, the specification of audio amplifier groove is 27mm * 2mm, sender is 8mm- 12mm, (below: =diameter), volume is about 95 decibels, sounding is little, thereby influenced voice effect, anti-theft effect is poor, and the thief can go smoothly when stealing easily.
Summary of the invention
The purpose of this utility model will design a kind of novel integrated electric vehicle anti-theft alarm device pronunciation device exactly, and it is little that it can overcome old money integral electric car burglar alarm pronunciation, the shortcoming of anti-theft effect difference.
The utility model is existing integral electric car burglar alarm pronunciation device structure to be transformed realize the purpose of this utility model: the utility model is little in order to overcome old money integral electric car burglar alarm pronunciation device sounding, the shortcoming of anti-theft effect difference, improved integral electric car burglar alarm pronunciation device, the piezoceramic piezo that adopts is bigger than old money integral electric car burglar alarm pronunciation device piezoceramic piezo, and, use an extraordinary gluing thin sheet at its back side, thin sheet is flexible, piezoceramic is fixed in the above, difficult drop-off when sounding, the air-flow concussion strengthens pronunciation; Piezoceramic piezo pronunciation groove changes greatly, piezoelectricity singing piece cements on the thin sheet, external two power leads of piezoelectricity singing piece are to the Car Burglar Alarm circuit card, carry electric current to piezoelectricity singing piece by circuit card during work, cause vibration, pronunciation, play antitheft effect, it is loud and clear to improve the back pronunciation, the volume height; The sound groove can be designed to recessed and protrude, and can place centre, also can place both sides; Integral electric car burglar alarm pronunciation device after the improvement, because of bigger space is arranged, enough air-flows reverberate, sounding is loud and clear, increased stereoeffect, volume can reach 115 decibels, makes Car Burglar Alarm play fright thief's effect in antitheft process, and cause peripheral people's attention, strengthened anti-theft effect.
Audio amplifier groove of the present utility model and thin sheet diameter dimension scope 40mm～55mm.
The utility model is compared with existing integral electric car burglar alarm pronunciation device, and a piezoceramic piezo that is characterized in of the present utility model reasonably combines with the annunciator main frame, makes its structure and sounding reach optimization.Loud when it is reported to the police, good anti-theft effect, cost is low.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in Fig. 1～3, be old money integral electric car burglar alarm pronunciation device scheme drawing, it contains reinforcing piezo plastic ring 1 and piezoceramic piezo 2 and pronunciation groove 3.The specification of piezoceramic piezo is 27mm * 0.6mm, and the specification of audio amplifier groove is 27mm * 2mm, and sender is 8mm- 12mm.Annunciator pronunciation device sounding is little, and anti-theft effect is poor.
Shown in Fig. 4～6, be the scheme drawing (the sound geosynclinal convex goes out) of a kind of concrete structure of the utility model, it contains reinforcing piezo plastic ring 11 and piezoceramic piezo 12 and pronunciation groove 13.With an extraordinary gluing thin sheet, thin sheet is flexible at the piezoceramic piezo back side, and piezoceramic is fixed in the above, difficult drop-off when sounding, and the air-flow concussion strengthens pronunciation.Adopting specification in the present embodiment is 35mm * 0.6mm piezoceramic piezo, so just make piezoceramic piezo of the present utility model bigger than old money integral electric car burglar alarm pronunciation device piezoceramic piezo, and, use the thin sheet of an extraordinary gluing 50mm * 0.4mm at the piezoceramic piezo back side, piezoceramic piezo pronunciation groove changes greatly 50mm * 2mm, make it that bigger pronunciation space be arranged, sound hole is 8mm- 12mm, reinforcing with 50 sheets is the pronunciation source, the audio amplifier groove of joining 50 again, the whole articulatory configuration system of composition.Adopt the piezoelectricity singing piece of 35mm * 0.6mm, cement on the sheet of 40- 55, use again on the sound groove of 40- 55, external two power leads of the piezoelectricity singing piece of 35 are to the Car Burglar Alarm circuit card, carry electric current to piezoelectricity singing piece by circuit card during work, cause vibration, pronunciation, play antitheft effect, it is loud and clear to improve the back pronunciation, the volume height.
Present embodiment is that the sound groove that protrudes in the structure shown in Fig. 4～6 is designed to recessed sound groove.
