Abstract: A sound playing device and a connection establishing method thereof are disclosed. The sound playing device comprises a wireless transmission module, a detection module, and a control module. The wireless transmission module is used for establishing a connection with an electronic device via a first or a second wireless transmission path, wherein the first and the second wireless transmission path are used for receiving an audio signal and a data signal respectively. The detection module detects whether the wireless transmission module is connected to the electronic device via the first or the second wireless transmission path. When the detection module detects that the electronic device is to be connected via the second wireless transmission path, it further detects whether the electronic device is connected via the first wireless transmission path. If yes, then the control module enables the connection via the second wireless transmission path.

Abstract: A method of adjusting an equalizer is disclosed. The method is applied to an electronic device for adjusting a plurality of gain values of the equalizer synchronously. The method of adjusting an equalizer of the present invention includes the steps of receiving an adjusting command; increasing or decreasing each of the gain values synchronously in an equimultiple way; storing adjusted gain values in a memory of the electronic device.

Abstract: An electronic device includes an image capture module and a processing unit. The image capture module is used for capturing a user's face image. The processing unit includes an image analysis module and an inquiry module. The image analysis module is signally connected to the image capture module for analyzing the face image and obtaining age data according to a face recognition result. The inquiry module is signally connected to the image analysis module for obtaining a user's hearing data according to the age data, wherein the hearing data is the minimum volume data audible to the user for different frequencies of sound.

Abstract: A sound collection equipment includes a speaker, a microphone and a processing unit. The speaker is used for generating a test sound. The microphone is used for receiving the test sound. The processing unit is electrically connected to the microphone and the processing unit. The processing unit is used for determining if the energy of the test sound exceeds a predetermined energy value and judging that the sound collection equipment is in a usage state when the test sound does not exceed the predetermined energy value.
