Abstract

The invention provides a sound volume control device and a mobile terminal. The mobile terminal comprises the sound volume control device which comprises a fingerprint identification unit, a processing unit and a sound volume control unit; the fingerprint identification unit is used for collecting fingerprint information of a user, the processing unit is used for comparing the collected fingerprint information of the user with preset fingerprint information and sending a control signal when the collected fingerprint information of the user is matched with the preset fingerprint information, the sound volume control unit receives the control signal and is started under the control of the control signal, and meanwhile the sound volume control unit receives sliding operations of the user and controls the sound volume of the mobile terminal according to the sliding operations of the user. The sound volume control device is easy to operate.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a volume control device and a mobile terminal. Background technique [0002] Currently, a push-type mechanical volume control device is usually provided on a mobile terminal (for example, a mobile phone) to control the volume of the mobile terminal when talking or playing audio. The push-type mechanical volume control device is usually arranged on the side of the mobile terminal, and the push-type mechanical volume control device receives the pressing operation of the user, and when the user presses one end of the push-type mechanical volume control device, the volume is increased; The other end of the push-type mechanical volume control device reduces the volume. Due to the limited life of the push-type mechanical volume control device, long-term pressing operation of the push-type mechanical volume control device is likely to cause damage to the push-type mechanical volume...
