An electronic device including a signal generating circuit and a movable sensing circuit is provided. The signal generating circuit generates a sensory signal through a signal source. The movable sensing circuit generates a feedback signal in response to a detection signal from the signal generating circuit, and transmits the feedback signal to the signal generating circuit. The signal generating circuit obtains a first distance value between the signal source and the movable sensing circuit based on the feedback signal, and adjusts the intensity of the sensory signal according to the first distance value.

Electronic device and signal generating circuit

An inspection method for inspecting the water resistance of an electronic device is provided, including providing a vacuum generator, using the vacuum generator to pump air out of the electronic device, stopping the pumping of air out of the electronic device when the air pressure in the electronic device is less than a predetermined pressure value, measuring the air pressure in the electronic device as a first pressure value after the pumping of air out of the electronic device has been stopped for a predetermined time, calculating the pressure difference D by subtracting a second pressure value from the predetermined pressure value, calculating the pressure difference d by subtracting the second pressure value from the first pressure value, and determining whether the electronic device is waterproof or not according to the pressure differences D and d.
