Abstract

The utility model relates to a double-purpose alarm integrated electric horn for the traveling and avoiding and the theft protecting and alarming of the bicycles and the boosted vehicles. The utility model is composed of an integrated block, a sounding element, a lightening element, a transfer switch, a push-button switch and a sensing head. The utility model can simultaneously send out sound and luminous signals, and the sound is as high as 80 db. Besides big sound, the utility model also has the advantages of few elements and reliable operation.

Description

The integrated dynamic loud-speaker of reporting to the police

The utility model belongs to preventing in the International Classification of Patents and uses or steal bicycle device (B62H) and car lighting or signalling apparatus (B60Q) group without authorization, particularly relates to using advancing of integrated package to hide signal, anti-theft alarm dual-purpose apparatus.

In prior art, the most approaching is the dynamic loud-speaker that replaces bicycle bell, is made up of sounding spare, discrete component, power supply and switch.Its electrical schematic diagram complexity, number of elements is many, and does not have anti-theft alarm function.

The purpose of this utility model provides a kind of bicycle, mini-motorcycle running signal, the dual-purpose integrated loudspeaker of warning of anti-theft alarm, and its number of elements is few, reliable operation.

Purpose realizes by following scheme:

Reporting to the police is equipped with sounding spare, illuminating part, circuit card, voltage transformer, sensing head, power socket in the housing of integrated dynamic loud-speaker at least and links to each other with button switch by electric wire, and housing is by with the loam cake of scattering sheet with to have a bottom of sound release aperture synthetic.The inboard of release aperture has a tubular of making one with bottom to help the operatic tunes.The inboard power socket in addition of bottom.Bottom by the power socket side also is equipped with the fixing knob of change-over swith and outer end thereof.Said sounding spare is made up of piezoelectric ceramics sheet, the vibration of thin membrane basin that connects together with it and basin frame, and the basin frame is fixed in the open end that helps operatic tunes pipe.The another side of basin frame is shaped on the voltage transformer seat.Illuminating part is at least one light-emitting diode.Circuit card is fixed by claw, and envelope has music-integrating block and corresponding a small amount of discrete component on the plate.Housing is installed on vehicle front by fixed support.Being installed near the button switch of handle links to each other with circuit in the housing by electric wire.Said sensing head is positioned at housing.

According to the sample that such scheme is made, not only have and inform the sound and optic signal of hiding, and when vibrations, can send the anti-theft alarm signal.Simultaneously owing to adopted integrated package, thereby number of elements is less, the functional reliability height.

Accompanying drawing 1 assembles scheme drawing for embodiment of the utility model.Accompanying drawing 2 is the electrical schematic diagram of an embodiment of the utility model.

Below in conjunction with accompanying drawing, embodiment is described.Can find out from accompanying drawing 1, be equipped with sounding spare, illuminating part 11, circuit card 10, voltage transformer 12, sensing head, power socket 14 in the housing of the integrated dynamic loud-speaker of reporting to the police at least and link to each other with button switch 1 by electric wire.Housing is synthetic by loam cake 8 and bottom 6.Loam cake 8 has scattering sheet 9.Bottom 6 has sound release aperture 2, and the inboard of release aperture 2 has a tubular of making one with bottom 6 to help the operatic tunes 7.The inboard of bottom 6 also has power socket 14.On the bottom 6 of power socket 14 sides, change-over swith 15 is housed, its outer end is fixed with knob 16, and this change-over swith 15 adopts double-pole eight stations, can do any circumference motion.The vibration of thin membrane basin 4 that sounding spare links to each other with this sheet at the bottom of by piezoelectric ceramics sheet 3, basin, the basin frame 5 that is fixed together with the basin mouth are formed.Basin frame 5 is fixed on the open end that helps the operatic tunes 7 pipes.Said basin frame 5 another sides are shaped on voltage transformer seat 13.Illuminating part 11 is at least one light-emitting diode.Circuit card 10 is fixed by two claws on the basin frame 5 and a claw on the voltage transformer seat 13.Circuit card 10 envelopes have music-integrating block and corresponding a small amount of discrete component.Housing is fixed on vehicle front by fixed support 17, and live wire and near the button being installed in handlebar are opened 1 link to each other (this example is two button switches).Said sensing head is a mercury switch in this example, also can use the vibration-sensing head, and be installed among the housing.

Find out that from accompanying drawing 2 music integrated block IC (this example is the octave integrated package) as many audio frequencies the source takes place, amplify that again through audio-frequency transformer (AFT) (the E19 ferrite is a magnetic core), promote sounding, illuminating part is luminous simultaneously through transistor (9013).

Sensing head and resistance (1M Ω), electric capacity (0.01 μ F) are formed the vibrations trigger circuit.When vehicle shook, mercury switch was connected, and has exported the warning energizing signal.Change-over swith is hidden signal and anti-theft alarm selection between the two as advancing.When change-over swith is got to the former, press two button switches, can send two kinds of audio frequency.Because the piezoelectric ceramics sheet is connected with the terylen membrane vibrating basin, shake through helping the operatic tunes to help, so voice output up to 80 decibels, it act as the electric capacity in parallel with sensing head (0.01 μ F) and prevents false triggering.Chemical capacitor among the figure (10 μ F) also plays interference protection, anti-error trigger action.The utility model adopts many integrated packages (for example KD-254), and used element total amount obviously reduces, and functional reliability improves.This routine power supply adopts dry storage battery two joints No. five, and the warning electric current is some μ A, maximum current 300mA.

Accompanying drawing 2 shows, the multistation of change-over swith helps the setting of car owner to gear.When reporting to the police, the user can not once turn off without authorization.
