A processing method, device and electronic equipment

Abstract

The invention discloses a processing method, a processing device and electronic equipment, wherein an external surface of the electronic equipment is provided with a flexible thin film, the flexible thin film is arranged at an external side of an electret sensor, when variation of air pressure conducted through the flexible thin film is detected, variation quantity of air pressure is determined, anoise reduction capacitance value is adjusted according to variation quantity of the air pressure, and noise reduction is executed for communication signals according to the noise reduction capacitance value. According to the method, the device and the electronic equipment provided by the scheme of the invention, the flexible thin film is arranged at the external side of the electret sensor, variation quantity of air pressure is conducted through the flexible thin film, thus, the capacitance value of the electret sensor is adjusted, noise reduction for the communication signals is realized, and a problem that the electret sensor is directly exposed at the external surface of the electronic equipment, consequently contaminated by dust and influenced in usage effects is avoided.

Description

technical field [0001] The invention relates to the field of control, in particular to a processing method, device and electronic equipment. Background technique [0002] Usually, in order to achieve the purpose of noise reduction in calls, a microphone is added to the back of the electronic device, such as a mobile phone. At present, the microphone used on the back of the mobile phone is usually an electret mic, and the electret mic changes the capacitance through the airflow to convert the sound signal into an electrical signal. [0003] However, when the electret mic is used for noise reduction, the electret is directly or indirectly exposed to the outer surface of the electronic device, which will be contaminated with dust, and the adhesion of dust will affect the size of the electret capacitance and reduce its use effect. Contents of the invention [0004] In view of this, the present invention provides a processing method, device and electronic equipment to solve th...
