Abstract

A device for booting a handheld apparatus by sound detection includes a base, a power-on device, a trigger switch, and an acoustic sensor. Upon the handheld apparatus being placed at the base to trigger the trigger switch, the trigger switch controls the power-on device to power on the handheld apparatus. After the handheld apparatus is powered on, the acoustic sensor detects a sound of the handheld apparatus and then controls a pressure head of the power-on device to move away. The device and its method for booting a handheld apparatus by sound detection come with the advantages of a simple and easy operation and a high efficiency.

Claims

1. A device for booting a handheld apparatus by sound detection, comprising:

a base, having an opening formed on a surface of the base;

a trigger switch, protruded from the surface of the base;

an acoustic sensor, disposed within the opening; and

a power-on device, including a pushing device and a pressure head;

wherein when the handheld apparatus is placed at the base, the trigger switch is triggered to control the power-on device to power on the handheld apparatus;

wherein when the handheld apparatus is turned on, the acoustic sensor detects a sound from the handheld apparatus, and the pressure head of the power-on device is controlled and moved away.

2. The device of claim 1, wherein the pushing device is a pneumatic cylinder, a hydraulic cylinder, or an electric motor.

3. The device of claim 2, further comprising a solenoid valve, which is a device coupled to the trigger switch electronically, and provided for controlling an operation of the pushing device.

4. The device of claim 3, wherein the power-on device is coupled to the solenoid valve electronically.

5. The device of claim 4, further comprising a time relay coupled electronically between the solenoid valve and the acoustic sensor, and the time relay being provided for blocking a mis-trigger of the acoustic sensor caused by a noise of the solenoid valve.

6. The device of claim 5, wherein the solenoid valve is provided for starting the time relay.

7. The device of claim 6, wherein the time relay blocks the mis-trigger of the acoustic sensor for substantially two seconds.

8. The device of claim 1, wherein the sound detected by the acoustic sensor is within a range from substantially 70 decibels to 90 decibels.

9. The device of claim 1, wherein the pressure head of the power-on device is pressed and rebounded with an air pressure substantially equal to 0.1±

0.02 MPa.

10. A method for booting a handheld apparatus by sound detection, comprising the steps of:

placing the handheld apparatus at a base and triggering a trigger switch disposed on the base;

controlling a power-on device by the trigger switch to power on the handheld apparatus; and

detecting a sound from the handheld apparatus by an acoustic sensor to control the power-on device to move away, after the handheld apparatus is turned-on to produce the sound.

11. The method of claim 10, wherein the trigger switch turns on a solenoid valve, and the solenoid valve controls a power-on device to power on the handheld apparatus.

12. The method of claim 10, wherein when the acoustic sensor detects the sound, the solenoid valve controls and moves away a pressure head of the power-on device.

13. The method of claim 10, wherein when the trigger switch turns on the solenoid valve to control the power-on device to power on the handheld apparatus, the solenoid valve starts a time relay to block a mis-trigger of the acoustic sensor caused by a noise of the solenoid valve.

14. The method of claim 13, wherein the time relay blocks the mis-trigger of the acoustic sensor for substantially two seconds.

15. The method of claim 10, wherein the solenoid valve controls a pneumatic cylinder of the power-on device to push a pressure head of the power-on device by an air pressure.
