Problems solved by technology

[0002] In the current hifi-level player, the volume potentiometer generally does not have a locking mechanism to limit its rotation in an unconscious state, which may easily cause the user to be stinging or even hurt the eardrum by the sudden increase in the sound during the listening process of using the earphone. Certain potential safety hazards in the use process affect the user's comfort when using the product

Abstract

The invention discloses a rotating locking mechanism of a displayer volume potentiometer. The volume potentiometer is fixedly arranged in a displayer shell body, a rotary knob of the volume potentiometer is exposed out of the shell body, a locking stirring block is arranged in the shell body, the locking stirring block can be connected with the rotary knob of the volume potentiometer in a clamped mode, an adjusting key which is used for conducting adjustment is arranged on the locking stirring block, the adjusting key is exposed out of the shell body, the adjusting key can drive the locking stirring block to be clamped with or separated from the rotary knob of the volume potentiometer, a positioning mechanism is further arranged in the shell body, and the positioning mechanism can be fixedly connected with the locking stirring block. A deadlocking function of the rotary knob of the volume potentiometer is achieved, the rotating locking mechanism of the displayer volume potentiometer is simple in structure and convenient to operate, the rotary knob of the volume potentiometer can not be rotated through friction and other motions of a user under an unconscious condition, the eardrums of the user are protected against damage, and use safety of a displayer is improved.

Description

technical field [0001] The invention relates to a volume adjustment mechanism of a player, in particular to a rotary locking mechanism for a volume potentiometer of a player. Background technique [0002] In the current hifi-level player, the volume potentiometer generally does not have a locking mechanism to limit its rotation in an unconscious state, which may easily cause the user to be stinging or even hurt the eardrum by the sudden increase in the sound during the listening process of using the earphone. Certain potential safety hazards in the use process will affect the user's comfort when using the product. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a rotary locking mechanism for the volume potentiometer of the player. The rotary locking mechanism of the volume potentiometer of the player has a simple structure and can quickly realize the locking and positioning of the knob of the volume potentio...
