Disclosed is a smart head-mounted device, and the smart head-mounted device comprises at least one lens and at least one arm, the arm is connected to the lens and has a cavity therein; further comprises a sound production apparatus provided inside the cavity and dividing the cavity into a front acoustic cavity and a back acoustic cavity; a sound outlet and a main sound leakage hole provided on the arm, the sound outlet is in communication with the front acoustic cavity, and the main sound leakage hole is in communication with the back acoustic cavity.

Smart head-mounted device

An acoustic device comprises a first closed cavity and a second closed cavity, at least a portion of a partition part flexibly deforms, the first closed cavity is adjacent to a vibration diaphragm, and the second closed cavity is far away from the vibration diaphragm; when the vibration diaphragm vibrates, the internal sound pressure of the first closed cavity changes, a flexible deformation part of the partition part deforms with the change, to flexibly adjust the volume of the first closed cavity; the second closed cavity encloses sound waves into the second closed cavity; and the Young's modulus or strength of at least partial region of the flexible deformation part is less than that of the wall of the first and/or the second closed cavity, the Young's modulus of entire region or partial region of the flexible deformation part is less than or equal to 8000 Mpa.

Acoustic device and electronic apparatus

Disclosed by the present invention is an acoustic device, comprising a sound generating unit. A first sealed cavity is formed at the rear side of a vibrating diaphragm of the sound generating unit, a mounting hole is provided on a cavity wall of the first sealed cavity, and a flexible deformation part is provided on the mounting hole. A second sealed cavity is formed at the outer side of the first sealed cavity, and the second sealed cavity encloses the sound wave generated during deformation of the flexible deformation part therein. The mounting hole is located on the first wall, and a groove is provided on the first wall at the periphery of the mounting hole towards the first sealed cavity. The flexible deformation part is fixed on the bottom of the groove, and a through groove is further provided on the first wall.
