Abstract

The utility model relates to a motor-driven selectable electronic musical bell which comprises a motor installed on a motor seat. The motor drives the drive gear set by the worm gear on the rotation shaft end of the motor and connects with an output axis to output horizontally with the crown-gear which is connected with a drive shaft. A drive shaft connected with the crown-wheel outputs the power vertically. A base is connected with one side of the motor seat on which a fixing ring is arranged, and the fixing ring is provided with a plurality of sound holes. A loudspeaker is inserted into the fixing ring. A plurality of binders are popped out on the perimeter of the base, and connected with a circuit board overhead. The circuit board is connected with the motor, the loudspeaker, an electric power source, a switch and a luminous element. While a music integrated circuit on the rear circuit board is started, the loudspeaker is caused to sound, the luminous element flickers following the music, and the output shaft acts simultaneously with the drive shaft.

Description

The bell with electronic music selected of motor transmission

The utility model is about a kind of bell with electronic music, is meant a kind of selectable bell with electronic music with the motor transmission especially, belongs to the technical field of toy.

The music bell of motor transmission at present as shown in Figure 1, has the touch structure 1 of a tubular and the scale structure 2 of a reed pectination, utilizes touch structure 1 to rotate and drive scale structure 2 generation sound equipments.As the variation of music will be arranged, then utilize to be located on the stack shell projecting point of appropriate location and to form.Because of being subject to the design of pronunciation touch structure, one first melody can not be expressed it fully according to the original work content, and a music bell can only have a first incomplete fixedly melody, can not can produce as integrated circuit: 1. song more than, 2. various animal callings, 3. train sound, ambulance sound, 4. sound miscellaneous such as phonetic synthesis sound.Therefore present motor transmission music bell has no the part of variation on vocal structure, but and can not be as the direct driven light-emitting element of integrated circuit, flicker with music and to flash.In addition, the touch structure 1 of tubular formula and the 2 essential special messenger's designs of the scale structure of reed pectination, and the manufacturing accuracy requirement is high, can produce music rhythm, and cost is higher.If only need to play as the of short duration ring of ten several seconds, then must match with the touch structure of limit switch 3 with the tubular formula, when making tubular formula touch structure rotate a circle, touch limit switch, make it to close.So, need increase part, the product valency is expensive, and the design people is improved.

The purpose of this utility model is to provide a kind of selectable bell with electronic music of motor transmission, still with motor as power resources, just still possess original drive characteristic, but the touch structure that salient point is set on the tubular and the scale structure of reed pectination have been cancelled, change by an electronic circuit and replace, direct supply and simple circuit are provided, particularly contain a music integrated circuit on the circuit, after direct supply starts electronic circuit, music integrated circuit spreads out of a whole first melody by loudspeaker, even can spread out of the various voice of different melodies at every turn, to reach the function of experiencing that present electronic music bell formula music box do not had, and can on circuit, be connected to light-emitting component, flash with musical sound, more can be by transmission shaft and the external outputting power of output shaft, connect various combination of actions and drive toy and beat or rotate, be different from and utilize power supply to drive revolution usually, the transmission tubular scale structure that contains suitable salient point touch structure and reed pectination has only the music bell device of incomplete fixedly music again.The utility model is if be used in the clock that gives the correct time on schedule and have doll action, and switch can omit, and of short duration music ring is played, and can be controlled by integrated circuit, is different from existing electronic music bell, and its of short duration music ring is played, and finishes with limit switch.Therefore, the integrally-built cost of the utility model reduces, and energy generation sound, light and the special effect of action, the member work simplification, can offer toy manufacturing industry, gift manufacturing industry, clock manufacturer use, make the dealer can develop the product of diversification, increase the surcharge of product, enhance competitiveness.
