SOUND TRANSMISSION DEVICES WITH BONE CONDUCTION Russian patent published in 2023 - IPC H04R9/02 

FIELD: acoustics.

SUBSTANCE: sound transmitting device with bone conduction, containing: a multilayer structure formed by a vibration unit and an acoustic transducer unit; and a base structure configured to load the multilayer structure, wherein at least one side of the multilayer structure is physically connected to the base structure. The base structure is configured to vibrate in response to an external vibration signal, and the vibration unit is configured to deform in response to vibration of the base structure; and the acoustic transducer unit is configured to generate an electrical signal depending on the deformation of the vibration unit, wherein the vibration unit includes at least one support bracket and a weight element, and the weight element is connected to the base structure through said at least one support bracket, wherein the acoustic transducer unit is located on the upper surface, lower surface or inside the at least one support bracket.

EFFECT: improved sound quality.
