Dust-removing method and dust-removing device for mobile terminal

Abstract

The invention discloses a dust-removing method and a dust-removing device for a mobile terminal. The dust-removing method comprises the following steps: after the current dust-removing cycle starts, determining a target dust-removing part of the mobile terminal according to user settings; judging the included angle between a reference part corresponding to the target dust-removing part and a horizontal plane meets a preset condition or not; if the included angle between the reference part corresponding to the target dust-removing part and the horizontal plane meets the preset condition, transmitting an ultrasonic electric signal to piezoelectric ceramic corresponding to the target dust-removing part and arranged in the mobile terminal, driving the piezoelectric ceramic to vibrate and performing dust removal on the target dust-removing part; and if the included angle between the reference part corresponding to the target dust-removing part and the horizontal plane does not meet the preset condition, executing the step of judging the included angle between the reference part corresponding to the target dust-removing part and the horizontal plane meets the preset condition or not as well as the subsequent step again until the current dust-removing cycle ends up. The dust-removing part of the mobile terminal is subjected to dust-removing treatment by the dust-removing method, so that better dust-removing effect and higher dust-removing efficiency can be removed.

Description

technical field [0001] The invention relates to the technical field of dust removal for mobile terminals, in particular to a dust removal method and a dust removal device for mobile terminals. Background technique [0002] With the development of mobile terminal technology, existing mobile terminals already have waterproof and dustproof functions. However, the dustproof function of most mobile terminals is limited to preventing dust from entering the inside of the mobile phone. For components with external openings such as earpieces, speakers, and receivers of mobile terminals (in this paper, these components are defined as dust-removing components), dust usually adheres to the external openings of the dust-removing components in large quantities, affecting the use of the corresponding dust-removing components. [0003] In the prior art, in order to prevent the dust attached to the external openings of the dust removal components such as mobile terminal earpieces, loudspeak...
