Abstract
The utility model belongs to a learning machine comprising a controller, a power amplification chip, and a horn and peripheral circuit thereof, wherein the power amplification chip is arranged inside the controller, and is connected with the horn and peripheral circuit thereof through the output port of the controller. In the handheld learning machine provided by the utility model, the power amplification chip is arranged in the controller, so that the space occupied by the power amplification chip is saved, the volume of the entire learning machine is reduced, and the system integration level is improved.
Description
Technical field
The utility model belongs to a kind of learning machine.
Background technology
The signal that existing learning machine is exported controller by the power amplification chip that links to each other with controller amplifies, and the signal with the output of power amplification chip drives loudspeaker and peripheral circuit work thereof then.Such setting because the power amplification chip has taken certain space, has increased the volume of learning machine.
Summary of the invention
The purpose of this utility model provides the learning machine that a kind of volume is little, integrated level is high.
For achieving the above object, the utility model has adopted following technical scheme: the utility model comprises controller, power amplification chip, loudspeaker and peripheral circuit thereof, described power amplification chip is arranged at controller inside, and links to each other with loudspeaker and peripheral circuit thereof by the output port of controller.
As shown from the above technical solution, built-in power amplifies chip in controller, has saved power amplification chip occupation space, has reduced the volume of learning machine on the whole, has improved the integrated level of system.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises controller 1, power amplification chip 2, loudspeaker and peripheral circuit 3 thereof, and described power amplification chip 2 is arranged at controller 1 inside, and links to each other with loudspeaker and peripheral circuit 3 thereof by the output port of controller 1.
Built-in power amplifies chip 2 in controller 1, two output ports is set on controller 1 links to each other with loudspeaker and peripheral circuit 3 thereof, and the signal of controller 1 output just can drive loudspeaker and peripheral circuit 3 work thereof, and realization the outer of learning machine put.Save power amplification chip 2 occupation space, reduced the volume of learning machine on the whole, improved the integrated level of system.
