Abstract

The invention discloses a dual-drive full-frequency bone conduction loudspeaker, and relates to the technical field of bone conduction audio transmission. The problems of lack of sound low-frequency output and high F0 value are solved. The dual-drive full-frequency bone conduction loudspeaker specifically comprises a magnet part, a sound body part and an elastic sheet supporting assembly part, themagnet part comprises U-shaped iron, a magnet, a washer sheet, an auxiliary magnet and an auxiliary washer sheet, and the U-shaped iron, the magnet, the washer sheet, the auxiliary magnet and the auxiliary washer sheet adopt a double-magnetic-circuit design; the voice body part comprises a voice coil, a fixing frame, an auxiliary voice coil and an auxiliary fixing frame. According to the invention, the structural design characteristics of double voice coils and double magnetic circuits are adopted; the vibration amplitude of the product can be increased; therefore, the sensitivity of sound and the effect of bass are effectively improved, the bass of the product is thicker and more comfortable, the elastic sheet supporting assembly part adopts a suspension supporting design, and the connected elastic sheet can be designed and modified according to requirements so as to change the amplitude of the elastic sheet supporting assembly part in the cavity and achieve the effect required by aclient.

Description

technical field [0001] The invention relates to the technical field of bone conduction audio transmission, in particular to a dual-drive full-frequency bone conduction speaker. Background technique [0002] Under normal circumstances, the sound we hear is formed by sound waves compressing the air. The sound waves pass through the compressed air, and the air pressure drives the middle ear tympanic membrane to the cochlea. From the ear ossicles to the cochlea, and finally to the auditory nerve, the bone conduction vibrator horn is a converter that can directly convert electronic signals into mechanical signals, and is widely used in wearable devices in the audio field to meet people's need for sound in specific situations. The creation of the bone conduction vibrator speaker transmits sound through vibration instead of applying pressure to the surrounding air. The audio signal transmission is very clear and can also meet the rigid needs of hearing-impaired patients. Nowadays, ...
