Described volume control switch is the third gear toggle switch.
Described push-button unit comprises first button that is used to send honk, and first button is connected with the signal input end of main control chip.
Described push-button unit also comprises second button, the 3rd button, the 4th button, the 5th button, and second button, the 3rd button, the 4th button, the 5th button all are connected with the signal input end of main control chip.
Further comprise power supply, power supply is connected with the power input of main control chip.
Described power supply is a dry cell.
The utility model beneficial effect is: the utility model includes loudspeaker, main control chip, is installed on the push-button unit on bearing circle surface, and loudspeaker are connected with the audio signal output end of main control chip, and push-button unit is connected with the signal input end of main control chip.In use, the user can be installed on the push-button unit input control signal on bearing circle surface by the utility model, be that the audio signal outputs such as musical sound that may command is stored in the main control chip are in advance given loudspeaker, sound by loudspeaker, thereby the function that makes carriage for children is abundant more, interest is higher.
Description of drawings
Fig. 1 is a frame principle figure of the present utility model.
In Fig. 1, comprise:
1---main control chip 2---volume control switch
3---loudspeaker 4---power supply
5---push-button units 51---, first button
52---second buttons 53---the 3rd button
54---the 4th buttons 55---the 5th button.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, as shown in Figure 1, a kind of carriage for children bearing circle sound effect control circuit that the utility model provides, it includes loudspeaker 3, main control chip 1, is installed on the push-button unit 5 on bearing circle surface, loudspeaker 3 are connected with the audio signal output end of main control chip 1, and main control chip 1 can be given loudspeaker 3 and drive loudspeaker 3 sounding by output audio signal; Push-button unit 5 is connected with the signal input end of main control chip 1, makes the user import control commands corresponding by push-button unit 5.
Be connected with volume control switch 2 between the audio signal output end of loudspeaker 3 and main control chip 1, the input end that is volume control switch 2 is connected with the audio signal output end of main control chip 1, the output terminal of volume control switch 2 is connected with loudspeaker 3, to control the volume that loudspeaker 3 are sounded; More particularly, described volume control switch 2 is the third gear toggle switch, and it comprises big volume gear, small volume gear, shutdown gear.When volume control switch 2 dialed to big volume gear, then loudspeaker 3 volume of sounding was bigger; When volume control switch 2 dialed to the small volume gear, then loudspeaker 3 volume of sounding was less; When volume control switch 2 dialed to the shutdown gear, then loudspeaker 3 can not be sounded.
Push-button unit 5 comprises first button 51 that is used to send honk, first button 51 is connected with the signal input end of main control chip 1, when the user presses first button 51, then main control chip 1 meeting is given loudspeaker 3 with the audio signal output of the honk of storage, send honk by loudspeaker 3, make the bearing circle of carriage for children have the higher sense of reality, further improve the interest of carriage for children.
