SPEAKERS Russian patent published in 2023 - IPC H04R9/06 

FIELD: acoustics, in particular speakers.

SUBSTANCE: speaker contains a vibrating unit consisting of a vibrating element and a vibrating housing. The vibration element is configured to convert the electrical signal into mechanical vibration, and the vibrating body is in contact with the user's facial skin. The speaker contains an elastic element elastically connected to a vibrating body. The speaker further contains a mass element coupled to the vibrating body via a first resilient member, the mass element being coupled to the first resilient member to form a resonant unit, and the vibrating unit generating a first resonant peak at the first frequency. In the frequency range below the first frequency, the vibration amplitude of the resonant unit exceeds the vibration amplitude of the vibrating body.

EFFECT: reducing the amplitude of vibrations of the vibrating body in contact with the user's face, reducing sound leakage, improving sound quality.
