Abstract

The invention discloses a volume-reduced bone conduction loudspeaker driver, which includes a panel, a vibration transmission plate, a vibration plate, and a bottom plate, on which an inner magnet and a ring magnet are fixed; The top surface of the magnet is fixedly provided with an inner magnetic guide plate, and the ring-shaped magnetic guide plate is fixedly arranged on the top surface of the ring magnet, and a gap is provided between the ring-shaped magnetic guide plate and the inner magnetic guide plate; The voice coil on the lower side of the board extends downwards in the gap; a washer is arranged on the top surface of the ring-shaped magnetic conducting plate, and is fixedly connected to the edge of the vibration-transmitting plate. The volume-reduced bone conduction loudspeaker driver of the present invention effectively improves sensitivity due to the use of gaskets and double magnet structures; at the same time, the shell is eliminated, and the vibration transmission piece is directly fixed on the magnetic circuit system by adding gaskets, thereby realizing bone conduction The speaker driver reduces the volume effect.

Description

technical field [0001] The invention relates to a design scheme for reducing the volume of a bone conduction loudspeaker driver. Background technique [0002] The reason why people can hear sound is because the vibration in the air transmits the vibration to the eardrum through the external ear canal, and the vibration formed by the eardrum drives the human auditory nerve. [0003] When the bone conduction speaker works, the driver pushes the shell of the bone conduction speaker to generate vibration, and the vibration frequency is in the audio frequency range. Because the shell of the bone conduction speaker is close to the human skin, the vibration generated by the bone conduction speaker is transmitted to the human auditory nerve through the human skin, subcutaneous tissue and bone, so that people can hear the sound. [0004] figure 1 It is a longitudinal sectional view of the structure of the prior art bone conduction speaker device. The bone conduction loudspeaker ge...
