A portable audio input/output device may include an assembly enclosure that contains electrical and mechanical components of the device. A substantially cylindrical frame may encircle the assembly enclosure and may be surrounded by a tube of seamless material. A top end of the tube of seamless material may fold over a top end of the substantially cylindrical frame, and a bottom end of the tube of seamless material may fold over a bottom end of the substantially cylindrical frame. A cover assembly may couple to a top end of the assembly enclosure and secure the top end of the seamless fabric. A charging foot may be coupled to a bottom end of the assembly enclosure and secure the bottom end of the seamless fabric.

An image capturing assembly including a composite circuit board, an image capturing component and a first audio component. The composite circuit board includes a hard board part and a first flexible board part that are directly connected to each other. The image capturing component is disposed on and electrically connected to the hard board part. The first audio component is disposed on and electrically connected to the first flexible board part.

A dynamic arrangement for loudspeaker grilles is disclosed. A first perforated grille is operable to move with respect to a second perforated grille. The relative movement is controlled to cause the two respective sets of perforations to fall in or out of alignment as required, leading to advantageous effects such as different levels of acoustic transparency.

A modular auditory low frequency sound reproduction and vibration generating speaker enclosure platform system for use to support a seating apparatus includes a main housing having a top wall, a bottom wall, a front wall, a rear wall, and a pair of side walls forming an internal chamber, a subwoofer speaker coupled to the main housing, an amplifier electrically coupled to the subwoofer, and a plurality of reflex ports coupled to the front wall of the main housing. The top wall of the main housing is designed to support the seating apparatus thereon. The amplifier is designed to activate the subwoofer to generate the sound pressure waves that project from the speaker to the seating apparatus and throughout the main housing. The generated sound pressure waves transferred along the top wall of the main housing delivers tremulous movement to the seating apparatus situated thereon.

Embodiments are disclosed for a loudspeaker for producing directed acoustic vibrations. In some embodiments, a loudspeaker includes an electromagnetic transducer including a diaphragm configured to generate acoustic vibrations. The loudspeaker may further include an aperture frame positioned in front of the diaphragm in a direction of propagation of the acoustic vibrations, the aperture frame covering only a portion of a radiating surface of the diaphragm and having a shape that corresponds to the contours of the diaphragm.

A piezoelectric sounding component includes a diaphragm that includes a metal plate and a piezoelectric body formed on the metal plate. The diaphragm bends and vibrates according to application of voltage to the piezoelectric body. A casing that includes a bottom wall, side walls, and a supporting portion to support the diaphragm in inside edge portions of the side walls. The side walls extending from edges of the bottom wall in a thickness direction and includes a first wall, a second wall positioned to face the first wall, and a third wall positioned between the first wall. Two or more terminals that are formed on the first wall or the third wall serve to apply voltage to the diaphragm. Two or more elastic adhesives join the side walls and the diaphragm between the two or more terminals and the diaphragm. Two or more conductive adhesives are formed on the two or more elastic adhesives and join the two or more terminals and the diaphragm. The diaphragm is supported by the supporting portion and accommodated in the casing so that a gap formed between the first wall and the diaphragm is smaller than a gap formed between the second wall and the diaphragm.

A resin housing having an electronic component and a method for manufacturing the same are disclosed. The resin housing includes an electronic component mounting film that includes a housing made of resin, a base film disposed along an inner surface of the housing, a circuit pattern layer formed on at least a surface opposite to a side of the housing of the base film, and an electronic component connected to the circuit pattern layer and mounted on a surface opposite to the side of the housing of the base film. The electronic component mounting film is integrated with the housing. An impact absorbing layer covers the electronic component of the electronic component mounting film and a periphery of the electronic component. The circuit pattern layer of the electronic component mounting film is not bent around a portion on which the electronic component is mounted.

A head-mounted display apparatus and an acoustic device disposed in the head-mounted display apparatus are provided. The acoustic device includes a speaker, a resonance box, and a waveguide. The resonance box is connected to the speaker. The waveguide is connected to the resonance box. The volume of the waveguide is greater than twice the volume of the speaker, and the length of the waveguide is greater than 5 times the thickness of the speaker.
