The invention belongs to the technical field of earphone equipment, and relates to a bone conduction loudspeaker. The bone conduction loudspeaking device comprises an external shell, a transduction unit and a vibration panel, the transduction unit is used for generating vibration and is positioned in the outer shell; one end of the transduction unit is connected with the vibration panel; the vibration panel is provided with a ventilation groove used for discharging vibration energy generated by the transduction unit. The number of the ventilation grooves is multiple, and the ventilation grooves are annularly distributed in the vibration panel. A human body in contact with the vibration panel and the vibration panel form a closed space with the ventilation grooves as the center, due to theexistence of the ventilation grooves, energy generated by vibration in the closed space can be discharged out of the ventilation grooves conveniently, and therefore the outer shell cannot sense the energy generated by vibration, and sound leakage caused by energy leakage into air is restrained. Therefore, the bone conduction loudspeaker provided by the invention effectively inhibits the problem ofsound leakage in the prior art.
Description
technical field [0001] The invention belongs to the technical field of earphone equipment, and in particular relates to a bone conduction loudspeaker that can be used for sound leakage suppression. 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 vibration and sound. When the bone conduction earphones work, the vibration of the transducer unit will drive the ear ...
