摘要： 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.

摘要： A thermophone includes an inner core and an outer shell coaxial with the inner core. The inner core and outer shell enclose a volume filled with gas. A pair of posts extend radially from the inner core to the outer shell and extend longitudinally between the inner core and the outer shell. At least one longitudinal slot is formed along the outer shell and a fluid seal covers the slot. A thermoacoustic active element is disposed in the volume and heated by modulated current to generate alternating pressure on the outer shell and produce acoustic signals.

摘要： A communication system may communicate by backscattered acoustic signals that propagate through a liquid or solid. In this system, one or more transmitters may transmit acoustic signals that travel to, and are reflected by, an acoustic backscatter node. The backscatter node may modulate the amplitude and/or phase of the reflected acoustic signals, by varying the acoustic reflectance of a piezoelectric transducer onboard the node. The modulated signals that reflect from the backscatter node may travel to a microphone and may be decoded. The backscatter node may include sensors, and the uplink signals may encode sensor readings. The backscatter node may harvest energy from the downlink acoustic signals, enabling the node and the sensors to be battery-free. Multiple backscatter nodes may communicate concurrently at different acoustic frequencies. To achieve this, each node may have a matching circuit with a different resonant frequency.

摘要： A loose hair collection device that attaches to the shower wall for collecting lost hair while a person with long hair takes a shower. The device includes a pair of bristle pads that can be selectively disposed in a side-by-side (vertical) position, in an shelf (“L”) position, or in a face-to-face (“U”) position. A flex connector restrains the bristle pads in these positions without additional support. The face-to-face position facilitates collection of loose hair, the shelf positions provides a soap holder, while the side-by-side position facilitates cleaning of the collected loose hair from the device. The device may also include a water-tight pouch for holding a mobile device, or a speaker (and display screen if desired) and Bluetooth capability for wirelessly connecting to a mobile device locate outside the shower.

摘要： A shaped component made of technical fabric for protection of the speakers of electronic devices with waterproofing characteristics of IPx7 degree or higher, which have water-tight speakers. In addition to the function of protection from solid particles, the invention is optimised for guaranteeing fast and efficient draining-off of the water that has penetrated into the water-tight speaker so as to recover as fast as possible the initial acoustic functionality, in an improved way as compared to the solutions currently available. The component according to the present invention comprises within it one or more openings covered by synthetic technical fabric with hydrophilic treatment, to guarantee rapid exit of the water that has entered the speaker module, and one or more openings covered by synthetic technical fabric with hydrophobic treatment, to favour entry of air into the volume in front of the speaker, thus ensuring proper emptying thereof. In detail, among the various possible embodiments, the present invention may be implemented as a multilayer die-cut part that combines a hydrophilic synthetic fabric with a hydrophobic synthetic fabric and with one or more layers of adhesive to enable assembly inside the end products.
