Abstract

The embodiment of the invention provides electronic equipment and a volume adjusting method thereof. The electronic equipment comprises a shell, a ceramic loudspeaker, a capacitance detection assembly, a processor and a driver; the ceramic loudspeaker is arranged in the shell and is provided with an exciter, and the exciter is connected with the shell; the capacitance detection assembly comprisesa first capacitor sheet, a second capacitor sheet and a detection chip. The first capacitor plate is connected between the exciter and the shell; the second capacitor plate is connected to one side, far away from the shell, of the exciter; the detection chip is electrically connected with the first capacitor plate and the second capacitor plate respectively, the first capacitor plate and the second capacitor plate form a variable capacitor unit, the capacitance value of the variable capacitor unit changes along with the deformation of the shell, and the detection chip is used for acquiring thereal-time capacitance value of the variable capacitor unit; the processor is electrically connected with the driver and the capacitance detection assembly, the driver is electrically connected with the exciter, and the processor controls the driver to adjust the output volume of the ceramic loudspeaker according to the real-time capacitance value.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device and a volume adjustment method thereof. Background technique [0002] Electronic devices are usually equipped with speakers, and traditional electronic devices are equipped with dynamic speakers. However, a sound hole needs to be provided on the screen of an electronic device equipped with a dynamic speaker, which not only affects the appearance of the electronic device, but also increases the difficulty of waterproofing the electronic device. [0003] Based on this, the speaker equipped with the electronic device is replaced with a piezoelectric ceramic speaker, and the ceramic speaker generates sound by pushing the housing of the electronic device, thereby avoiding opening a sound hole on the screen of the electronic device. [0004] However, when the housing of the electronic device is held by human hands, the resonance point of the electronic device ...
