The present invention relates generally to a headphone control system, and particular to the headphone control system activating power saving.
An operation of the Bluetooth headphone may be controllably adjusted either by the device to which the headphone is wirelessly connected, or by the button on the headphone. Such operation may include the volume adjustment and/or the power on and off. Sometimes, the user may temporarily take off the headphone for either resting or being interrupted by something, a manual power-off action may be bothersome.
Therefore, it is desired to have the headphone equipped with a smart control system which may efficiently verify whether the headphone is currently requisitely used by someone for maintaining operation, or otherwise switching to a power saving mode.
To achieve the above object, a headphone control system for use within a headphone includes a temperature sensor for detecting whether the circumference temperature of the headphone is relatively far from the human temperature implying the headphone is no longer worn by the user, and a gravity sensor for detecting whether the headphone is stationary implying that the headphone is not used for enabling a power saving mode, or is moving implying that the headphone is not yet unused for maintaining operation. The detection constantly is applied to the headphone disregarding whether the headphone is in an operation mode or a power saving mode so as to efficiently have the headphone operated in response to currently using or power-saved in response to non-using.
Other advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Referring to
When the headphone is powered on, the temperature sensor constantly detects the circumference temperature of the headphone. The headphone maintains the operation or playback status when the temperature is unchanged and/or corresponding to the human temperature in a regular manner. When the temperature is changed and/or not corresponding to the human temperature in an irregular condition, the gravity sensor further detects whether the headphone is stationary or not. Under such a temperature irregular condition, when the headphone is further detected to be stationary, the headphone is switched to a power saving mode. Understandably, this situation may be referred to the user taking off the headphone temporarily, and the sound derived from the device may be temporarily suspended. Notably, such a power saving mode may be triggered in 30 seconds rather than instantly, as the operation of the screen power saving mode used in the computer or the mobile phone. In opposite, when the headphone is further detected to be moving under the aforementioned temperature irregular condition, the headphone is set/switched to in the operation mode. Understandably, this situation may be referred to the user putting on the headphone. In conclusion, the user does not need to manually control the sound or the power of the headphone when he takes off the headphone or puts on the headphone again advantageously.
Although the present invention has been described with reference to particular embodiments, it is not to be construed as being limited thereto. Various alterations and modifications can be made to the embodiments without in any way departing from the scope or spirit of the present invention as defined in the appended claims.
