A two-way receiver includes a cylindrical frame, a yoke dividing an internal space of the frame and including a cylindrical portion, a first flange portion formed at an outer periphery of the cylindrical portion, a connection wall bent downward from the first flange portion, a second flange portion formed at an outer periphery of the connection wall, and a communication hole formed by deleting a portion of the connection wall and second flange portion. A first speaker unit is installed above the yoke, and a second speaker unit below the yoke. A protector coupled to a lower portion of the frame protects the second speaker. A bass duct formed on an outer periphery of the first speaker unit has a sound emission hole for emitting a sound of the first speaker unit emitted to the communication hole of the yoke to a position spaced apart from the communication hole.

Various implementations include seats and related loudspeakers. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly including: at least one driver for generating an acoustic output; and an acoustic exit fixed in the seat backrest portion and angled to provide the acoustic output to a location below a nominal ear position of an occupant of the seat, wherein an angle of the at least one driver provides the acoustic output to achieve a consistent frequency response across a range of positions deviating from the nominal ear position, wherein the angle of the at least one driver is configured to be adjusted in response to a recline angle of the seat reaching a threshold.

Voice responsive in-wall devices are provided. In one example implementation, a power switch includes a housing mountable on or at least partially within a surface. The housing can have a front panel. The power switch can include an interface element disposed on the front panel and operable to receive a user input. The power switch can include a power interrupter operable to control power delivery to the powered load based at least in part on interaction with the interface element. The power switch can include one or more microphones operable to obtain audio input. The power switch can include one or more speakers configured to provide audio output. The power switch can include a communications interface operable to communicate data associated with the audio input over a communication link.

A computing device may include a display, an audio output device, a sensor to detect the position of the display relative to the audio output device, and a processor to receive the detected position of the display and adjust audio output from the audio output device based on the detected position of the display.

A showerhead assembly with a plurality of speakers is disclosed. The illustrative showerhead assembly includes a showerhead to exert fluid, a support structure to transport the fluid to the showerhead, and a plurality of speakers to exert sound with a consistent directionality. The showerhead assembly illustratively includes a dome housing having an inner wall and an outer rim, a showerhead to exert fluid, a support structure extending from a center of the housing such that the support structure has a first end attachable to a wall or ceiling and a second end distal from the first end and the support structure transports the fluid to the showerhead, and a plurality of speakers disposed on the support structure such that the speakers are directed toward the inner wall of the housing and the speakers generate and exert sound with a consistent directionality.

Acoustic loudspeaker (10) comprising a cabinet (12) extending in a direction (L), and a speaker (14) defining an acoustic axis (X). The cabinet defines a first axis (V1) perpendicular to the direction, and a second axis (V2) perpendicular to the direction and to the first axis.

The acoustic loudspeaker is intended to be used in a first configuration, wherein the first axis is essentially vertical, and a second configuration, wherein the second axis is essentially vertical.

The speaker is movable relative to the cabinet around an axis of rotation (D) between a first position, wherein the acoustic axis defines with the second axis a first angle less than 30°, and a second position, in which the acoustic axis defines with the first axis (V1) a second angle less than 30°. The axis of rotation makes two angles between 40° and 50° with the first axis and the second axis.

In an embodiment, an earphone having a solid earphone body is provided. A first mounting recess is formed in a first end of the earphone body. A first acoustic driver is disposed in the first mounting recess. At least a first sound bore is formed in the solid earphone body. The at least a first sound bore fluidly communicates with the first mounting recess and a first exit port formed at a second end of the earphone body. The second end of the earphone body is configured to be placed in an ear canal of a user. The earphone can be fabricated by a method that includes defining negative spaces for the first acoustic driver and the at least a first sound bore in a virtual model of the earphone body.

Aspects of the present disclosure provide an audio output mode adjustment structure that can include a sound output channel communicating an interior and an exterior of the electronic device and an adjusting unit. An opening of the sound output channel is located at the top of the electronic device. The adjustment unit moves relative to the opening of the sound output channel so that when the electronic device outputs audio in a loud-speaking mode, the adjustment unit does not cover the sound output channel, and sound waves propagate in a straight line through the opening of the sound output channel, and when the electronic device outputs audio in the handset mode, the adjustment unit covers the opening of the sound output channel, so that the sound waves propagate toward a display screen side of the electronic device through the opening of the sound output channel.

A cooling device generating unidirectional air flow to cool an electrical component. The cooling device is an equivalent of an electrical acoustic diode to make air flow only one direction. A speaker generates air flow in a first passageway to a cavity, and then expels air out from the cavity through a second passageway. An electrical component is cooled by the air flow, and may be positioned adjacent the passageways, or positioned in the cavity. In one example, eyewear having an electrical component positioned in a temple is cooled by the cooling device.

The present disclosure relates to an acoustic output apparatus. The acoustic output apparatus comprising: at least one low-frequency acoustic driver that outputs sound from at least two first sound guiding holes; at least one high-frequency acoustic driver that outputs sound from at least two second sound guiding holes; and a controller configured to cause the low-frequency acoustic driver to output sound in a first frequency range, and cause the high-frequency acoustic driver to output sound in a second frequency range, wherein the second frequency range includes frequencies higher than the first frequency range.
