Abstract

The invention belongs to the technical field of earphone equipment, and relates to a bone conduction loudspeaker. A bone conduction loudspeaker comprises an outer shell, a transduction unit and a vibration panel, and the transduction unit is used for generating a vibration transduction unit and is located in the outer shell; the bone conduction loudspeaker further comprises a vibrator support, andthe transduction unit is located in the vibrator support. The oscillator support is located in the outer shell, and one end of the oscillator support is connected with the vibration panel. Accordingto the bone conduction loudspeaker provided by the embodiment of the invention, the transduction unit is located in the vibrator bracket, and one end of the vibrator bracket is connected with the vibration panel. The oscillator support is located between the transduction unit and the external shell and isolates the transduction unit from the external shell. And one end of the vibrator bracket is connected with the vibration panel, so that the vibration panel is isolated from the external shell. When the transduction unit vibrates, the outer shell cannot sense the vibration of the transductionunit and cannot sense the vibration of the vibration panel, and no vibration is transmitted to the outer shell, so that no sound leakage is generated.

Description

technical field [0001] The invention belongs to the technical field of earphone equipment, and in particular relates to a bone conduction loudspeaker. Background technique [0002] Bone conduction is a sound conduction method, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph fluid transmission, screw, auditory nerve, and auditory center. Compared with the classic sound conduction method that generates sound waves through the diaphragm, bone conduction saves many steps of sound wave transmission. Earphones that use this sound wave transmission method, that is, bone conduction earphones, are very popular at present and have a wide range of applications. [0003] The principle of bone conduction earphones is to produce sound through vibration. When the bone conduction earphone is working, the vibration of the transducer unit drives the ear shell to vibrate, and part of ...
