Document Type and Number:
WIPO Patent Application WO/2021/000065
Kind Code:
A1
Abstract:
Provided in the present application is a control method for reducing the vibration of a second housing of a mobile terminal. The mobile terminal comprises a first housing, a second housing and an actuator, the actuator cooperating with the first housing to form a drive system to excite the vibration of the second housing. The control method comprises the following steps: installing an additional vibrator in any position area on the second housing, measuring a vibration response of the position area under a first preset condition and a second preset condition; calculate a system transfer function of a drive system and the additional vibrator; providing a signal processing unit used for processing an input signal of the additional vibrator to obtain a vibration response of the position area under a third preset condition; adjusting a transfer function value of the signal processing unit so that the vibration response value of the position area under the third preset condition is 0; calculating the transfer function value H3(S) of the signal processing unit; setting H3(S) as a preset transfer function of the signal processing unit. The present application may effectively counteract the vibration of the second housing and improve user experience.
