The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include an ear hook, a core housing, and a circuit housing. The ear hook may include a first plug end and a second plug end. The ear hook may be surrounded by a protective sleeve. The protective sleeve may be made of an elastic waterproof material. The core housing may be used for accommodating an earphone core. The core housing may be fixed to the first plug end and elastically abutted against the protective sleeve. The circuit housing may be used for accommodating a control circuit or a battery. The circuit housing may be fixed to the second plug end. The control circuit or the battery may drive the earphone core to vibrate. The vibration of the earphone core may generate a driving force to drive a housing panel of the core housing to vibrate. The driving force may be not parallel to a normal line of the housing panel. In the present disclosure, the core housing may elastically abut against the protective sleeve surrounding the ear hook to improve the overall waterproof effect of the loudspeaker apparatus and simplify the manufacturing and assemble process of the loudspeaker apparatus.

A device includes an audio assembly and a housing defining an aperture that interfaces with the audio assembly at an interior surface of the housing. The device includes stanchions coupled to an exterior surface of the housing at a location of the aperture and a cover coupled to the stanchions and free of contact with the housing. The device includes a drainage channel extending between the cover, the exterior surface of the housing, and the stanchions. The drainage channel includes a first portion defining an inlet of the drainage channel, and the first portion has a first width defined by the stanchions. The drainage channel includes a second portion defining an outlet of the drainage channel, and the second portion has a second width defined by the stanchions. The stanchions are tapered in shape so that the first width is wider than the second width.

An underwater sound generation device may be used for effective control of algae and other microorganisms in ponds and lakes. The sound projector may comprise a thermoacoustic sound transducer and an electronic unit for controlling the operation of the projector. The thermoacoustic projector may include a freestanding carbon nanotube (CNT) film encapsulated between two vibrating plates. The inert gas filled thin acoustical cavity provides a piston-type displacement of the plates and supports a high-temperature operation. A power supply driver, controlling the operation of the sound radiating system, may include a pulse generator, high-power switch amplifier, and a cable, connecting the projector with an electronic driver. The sound control system may provide an omnidirectional sound pressure level in a wide frequency range to affect the algae growth ecosystem over large distances.

A sounding component in an electronic device includes a box and a sounding system disposed in the box. The sounding system includes a front cavity, a rear cavity, and a damping component adapted to slow down an airflow from the rear sound cavity to enter a cavity inside the electronic device at a low flow rate and thereby weaken impact of the airflow on a housing of the electronic device, decrease amplitude, and dampen or alleviate housing vibration.

An electronic device is provided. The electronic device includes frame constituting at least a part of the side exterior of the electronic device, an internal mechanical element disposed inside the frame, multiple frame holes formed through the frame at a predetermined interval in an identical shape, an air channel comprising a first hole, at least a part of which is formed through the internal mechanical element in a first direction so as to be connected to at least one of the multiple frame holes, and a second hole formed through the internal mechanical element in a direction perpendicular to the first direction so as to be connected to the first hole, an air vent disposed in the second hole of the air channel, and a speaker channel connected to remaining holes of the multiple frame holes and connected to a speaker module.

The present disclosure relates to a pair of glasses. The pair of glasses may include a frame, one or more lenses, and one or more temples. The pair of glasses may further include at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, and a controller. The at least one low-frequency acoustic driver may be configured to output sounds from at least two first guiding holes. The at least one high-frequency acoustic driver may be configured to output sounds from at least two second guiding holes. The controller may be configured to direct the low-frequency acoustic driver to output the sounds in a first frequency range and direct the high-frequency acoustic driver to output the sounds in a second frequency range. The second frequency range may include one or more frequencies higher than one or more frequencies in the first frequency range.
