These and other objects, features and other advantages of the present invention will become more apparent by describing in detail preferred embodiments of the present invention with reference to the accompanying drawings. Hereinafter, a smartphone module having an automatic power control function according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view schematically showing a smartphone module having an automatic power control function according to an embodiment of the present invention.

1, a smartphone module 100 according to the present invention is a smartphone module having a stereo jack 140 that can be coupled to a stereo socket of a smartphone. The smartphone module includes a circuit board (not shown) 110); And a battery unit 120.

The controller 111 is automatically powered when the stereo jack 140 of the smartphone module is inserted into the stereo socket of the smartphone and the stereo jack 140 of the smartphone module is disconnected from the stereo socket of the smartphone So that the power is automatically cut off.

The battery 120 is preferably a member that is coupled to a predetermined position of the circuit board 110 to supply power to the circuit board 110 and the battery is configured to be replaceable on the rear surface of the housing of the smartphone module 100 Do.

The smartphone module 100 of the present invention may further include a light emitting unit 130 formed at a predetermined position of the circuit board 110 and adapted to emit light by power control of the control unit 111. Preferably, the light emitting unit 130 is configured to emit light when the smartphone module 100 is connected to the smartphone, and is configured to be embedded at one end of the smartphone module 100.

FIG. 2 is an explanatory view schematically showing the configuration of a stereo jack of a smartphone module and a stereo socket of a smartphone according to an embodiment of the present invention, and FIG. 3 is a circuit diagram of a smartphone module according to an embodiment of the present invention .

2 and 3, the smartphone module of the present invention is a device capable of performing various functions in connection with a smartphone. When the smartphone module 100 is connected to the smartphone 200, the internal power of the smartphone module 100 is activated. If the smartphone module 100 is not connected to the smartphone 200, The power supply unit circuit of the smartphone 100 confirms that the smartphone module 100 and the smartphone 200 are not physically connected, and the power supply is cut off or enters the low power consumption state.

Specifically, when the stereo jack 140 of the smartphone module 100 is inserted into the stereo socket 210 of the smartphone 200, the stereo socket 210 of the smartphone 200 is connected to the stereo R or L The operation of the internal power supply circuit is controlled using the output level of the internal power supply circuit, or the connection with the smartphone 200 is determined by using the signal. The stereo socket 210 of the smartphone 200, that is, the stereo R / L terminal is an analog output terminal that can not output DC power and outputs a voice signal. The output level of the output terminal is outputted as a low boundary voltage or less to be used as a signal for confirming the connection state between the smartphone module 100 and the smartphone 200.

For example, the stereo socket 210 of the smartphone 200 corresponds to a female socket of the stereo connector, and the presence or absence of the connection of the stereo jack 140 of the smartphone module 100 is implemented as a physical switch, It is possible to make a signal to distinguish whether the stereo jack 140 is connected.

Here, the DCDC element is ON when the ON / OFF port of the element is at a low level, and is OFF when it is at a high level. That is, when the smartphone module is not connected to the smartphone, the ON / OFF pin (PIN) of the U5 DCDC LDO device turns OFF in the pull-up state of the internal battery power, and the output of U5 is 0V Since the VCC of the module is not applied, the module consumes about 1 or less of the consumption current of the shutdown state of U5. On the other hand, when the smartphone module is connected to the smartphone, the stereo jack J2 is connected to the smartphone, the U5 ON / OFF pin of the pull-up state is lowered to low, VCC is supplied and the smartphone module is powered up.

Also, the power control using the smartphone module according to the present invention may be performed by changing the power mode by observing the output level of the smartphone with the control unit of the smartphone module. For example, when the smartphone module is not connected to the smartphone, the smartphone module waits in the idle state of the lowest power mode, and when the smartphone module is connected to the smartphone, the communication standby Standby " state.
