Abstract

The utility model relates to an electronic bell which is used on bicycles, tricycles, electric vehicles, Boosted vehicles or other vehicles. When people or other vehicles are in front of the vehicles, the electronic bells send out alarm call in order to inform the counterpart to let by. The electronic bell sounds by the application of electronic circuits and electronic elements. So long as switching on some block trigger signal after switching, the circuit can generate audio signal oscillation. The driving loud-speaker sends out sound through the magnify output of a triode. Compared with the existing bicycle bells, the electronic bell has the advantages that when a switch is pressed, the electronic bell has high electro-acoustics conversion ratio, fast reaction and electricity saving, and various sounds can be sent out as required. Therefore, the utility model is the update product of the existing bicycle bell and electric horn.

Description

Electronic bell

The utility model Electronic bell is to be used for bicycle, tricycle, battery truck, power assist vehicle or other vehicles, when pedestrian or other vehicle are arranged before the above-mentioned vehicle, stir the trigger switch of Electronic bell, Electronic bell just sends alarm call, notes dodging to notify the other side.

Now be used for the bicycle bell of above-mentioned various vehicles or electric horn and all be old product decades ago.Bicycle bell is the mechanical impact formula, and firmly bigger when pressing bicycle bell, sounding is slow.Electric horn is an electromagnetic type, and electricity consumption relatively takes, the sound dullness.

Electronic bell provides a kind of novel alarm device for above-mentioned various vehicles, it adopts the manner of articulation of analog audio integrated circuit to be applied on the bicycle bell, be the upgrading products of existing bicycle bell and electric horn, be particularly useful for power assist vehicle and new bicycle, and progressively replace existing bicycle bell and electric horn with this.

The pronunciation of Electronic bell is finished by the following method: it uses the analog audio circuit that monolithic integrated optical circuit constitutes, circuit promptly enters quasi-operating status after the energized, as long as connect a certain shelves trigger pip, circuit can produce the sound signal vibration by predefined program, amplify output by triode, drive loudspeaker and sound.If connect another grade trigger pip, just that sends another kind of sound.

Electronic bell can send multiple sound as required, as:

1. original various bicycle bell sound, electric horn sound.

2. play the sound equipment of alarm effect.

3. " please note " anthropomorphic dummies' such as " getting out of the way " voice.

Compare with electric horn with existing bicycle bell,, have lot of advantages because of Electronic bell is that employing electronic circuit and electronic component are next soniferous:

1. press switch, sounding immediately is so reaction is very fast.

2. the electroacoustic conversion ratio is than higher, so very power saving.

3. can send various sound, to adapt to the needs of different occasions.

Now be further described in conjunction with the accompanying drawings.

The structure of Electronic bell such as accompanying drawing 1, in shell (1): loudspeaker (2) is equipped with in the front, and loudspeaker is the miniature loudspeaker that aims at the Electronic bell design.Electronic circuit board (3) is housed above, comprises integrated circuit, triode, resistance on the electronic circuit board.Power supply (4) is housed below, is connected with switch (6) with electric wire (5) in addition, toggle switch is with the various sounding of control Electronic bell.Whole Electronic bell has supporting base (7) can be contained in easily on the above-mentioned various vehicle.

The principle of Electronic bell such as accompanying drawing 2, electronic circuit board (3) input termination power (4), output termination loudspeaker (2) connects several gear switch (6) therebetween, as long as the extremely a certain shelves of toggle switch, Electronic bell can send certain alarm sound on demand.

Claims

1, Electronic bell is to be used for bicycle, tricycle, battery truck, power assist vehicle or other vehicles, and when before the above-mentioned vehicle other vehicles being arranged, to send alarm call, it is soniferous to it is characterized in that adopting electronic circuit and electronic component.

2, the Electronic bell of stipulating according to claim 1, it is characterized in that in shell (1): loudspeaker (2) is equipped with in the front, electronic circuit board (3) is housed above, power supply (4) is housed below, be connected with switch (6) with electric wire (5) in addition, whole Electronic bell has supporting base (7) can be contained in easily on the above-mentioned various vehicle.

3, be electronic circuit board (3) input termination power (4) according to claim 1 or its characteristic of the described Electronic bell of claim 2, output termination loudspeaker (2), connect several gear switch (6) therebetween, as long as toggle switch is to a certain shelves, Electronic bell can send certain alarm sound on demand.
