SYSTEMS, METHODS AND DEVICES FOR OUTPUT OF ACOUSTIC SIGNALS Russian patent published in 2023 - IPC H04R25/00 

FIELD: acoustics.

SUBSTANCE: device for outputting audio signals, comprising: a bone conduction unit configured to generate a bone conduction acoustic wave; an air conduction unit configured to generate an air conduction acoustic wave, wherein the air conduction unit includes one or more vibrating diaphragms physically coupled to at least one of the bone conduction unit or housing, wherein the air conduction acoustic wave is generated based on said one or more vibration diaphragms and vibration of said at least one of the bone conduction unit or housing, the bone conduction acoustic wave and the air conduction acoustic wave represent the same sound signal, and the phase difference between the bone conduction acoustic wave and the air conduction acoustic wave is less threshold value; and a housing configured to receive at least a portion of the bone conduction assembly and an air conduction assembly, wherein at least one of said one or more vibrating diaphragms includes a main portion physically connected to the bone conduction assembly, the main portion includes a base plate and a side wall defining a subspace for receiving at least a portion of the bone conduction node; and an auxiliary portion physically connected to the housing; or at least one of said one or more vibrating diaphragms includes an annular structure, an inner wall of the vibrating diaphragm surrounds a bone conduction unit, and an outer wall of the vibrating diaphragm is physically connected to the housing.

EFFECT: improved audio quality, audio enrichment, improved user experience of audio, and reduced audio leakage.
