Abstract

The utility model provides an electronic acoustooptical top which belongs to a toy for children. The utility model is characterized in that the top is hollow, and a light-emitting and sound-emitting circuit and centrifugal type trigger switches are arranged in an inner cavity of the top, wherein, the light-emitting and sound-emitting circuit is composed of a music chip, a loudspeaker and a light-emitting diode which are respectively controlled by the two centrifugal type trigger switches. The centrifugal type trigger switches have the characteristics that when the top stops, the centrifugal type trigger switches are switched off; when the top vertically rotates, the two switches are automatically switched on under the action of the centrifugal force, the light-emitting and sound-emitting circuit is switched on, the top emits light, and simultaneously, the top plays music. The utility model can increase pleasure for players.

Description

Electronic acoustooptical top

The utility model belongs to a kind of gyro.

Gyro is a kind of toy for children, and steel ball is arranged below, and rope twines during object for appreciation, and firmly draw-string can make its upright rotation, and therefore the gyro no change plays the comparison dullness in decades.

The purpose of this utility model provides a kind of electronic acoustooptic gyro, during this gyro rotation, can send light and music simultaneously, heightens the enjoyment.

Below in conjunction with the description of drawings the technical solution of the utility model.

Fig. 1 is a longitudinal sectional view of the present utility model.

Fig. 2 is the luminous and sounding type circuit diagram.

Fig. 3 is centrifugal trigger switch structural representation.

Content of the present utility model is:

1, referring to Fig. 1, gyro 1 is hollow, and 2 li of inner chambers have luminous and sounding type circuit 4 and centrifugal trigger switch 5;

2, referring to Fig. 2, the composition of luminous and sounding type circuit is: the base stage of the output termination triode BG of Music Clip IC, the colelctor electrode of triode BG meets loudspeaker Y, and after two light emitting diode D1 and the D2 parallel connection, K2 connects with trigger switch, the one end is connected on the colelctor electrode of triode, another termination power cathode, one of trigger switch K1 terminates at positive source, and the other end is connected on the trigger end of Music Clip IC, above-mentioned two light emitting diode D1 and D2 be installed in gyro above, label is 3.

3, referring to Fig. 3, the structure of centrifugal trigger switch is: permanent magnet 7 is arranged in the middle of the inner chamber of horizontal tubular shell 6, tube cavity is divided into two chambeies, a steel ball 8 is respectively arranged in each chamber, and two rivets 9 are fixed in the outer end in each chamber, two rivets in left side and steel ball, form K switch 1, two rivets on right side and steel ball are formed K switch 2.

Operation principle is: when gyro was static, two steel balls were inhaled in the both sides by permanent magnet, and this moment, K switch 2 and K1 disconnected; When gyro uprightly rotated, under action of centrifugal force, steel ball overcame magnetic force, rolled the outer end to inner chamber, run on the rivet, and with two rivet short circuits, i.e. K1, K2 closure, the K1 closure triggers Music Clip, and loudspeaker is emitted melodious music; The K2 closure, two light emitting diodes 3 are luminous, the formation ring of light on gyro.

The utility model compared with prior art when gyro rotates, can be played out music automatically, the ring of light occurs, heightens the enjoyment to the entertainer.
