An improved microactuator for use in a contact hearing aid, wherein the microactuator includes a one-piece membrane. The one piece membrane being adapted to prevent moisture from entering the microactuator through the microactuator reed opening when the contact hearing aid microactuator is placed in the ear canal of a patient.

An electronic device is provided. The electronic device includes a speaker module. The speaker module includes an enclosure including a first housing and a second housing and a speaker driver included in the first housing. The second housing includes an adsorption cavity forming a back volume of the speaker driver, a variable structure included in at least a part of the second housing, at least one vent hole for ventilation between the adsorption cavity and an external environment, and a housing cover fixed to the variable structure. The adsorption cavity is filled with an adsorptive filler.

Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end, and including an inner eartip body and an outer eartip body. The inner eartip body has a sidewall that extends between the interfacing end and the attachment end, and includes a groove formed in an outer surface of the sidewall. The outer eartip body is sized and shaped to be inserted into an ear canal and extends from the interfacing end toward the attachment end of the eartip.

A light speaker structure with a ring handle includes a speaker body, a speaker enclosure, a lighting mechanism and an auxiliary mechanism. The speaker body is mounted within the speaker enclosure, and the auxiliary mechanism is mounted on the speaker enclosure. The lighting mechanism includes a lampshade, a light strip, and LED beads. The light strip is mounted within the lampshade. The LED beads are fixedly connected to the light strip and electrically connected to the speaker body. The light strip is disposed in a laterally inverted C-shape around the speaker enclosure. The lampshade covers the light strip, so that the light strip is held between the lampshade and the speaker enclosure. The light strip and the lampshade are so shaped that they can be arranged around the speaker enclosure, thereby achieving a better lighting effect, providing a larger lighting area and producing a stereoscopic effect.

An information handling system to wirelessly transmit and receive data may include a base chassis including a metal C-cover and a D-cover, the metal C-cover to house a speaker grill, the speaker grill covering a speaker to emit audio waves; a speaker grill platform antenna formed within the C-cover from a portion of the speaker grill to emit a target radio frequency (RF), including: a slot formed around the portion of the speaker grill to form a peninsula on the speaker grill that is physically separated from the C-cover; a cavity formed behind the peninsula between the C-cover and the D-cover, the cavity including walls formed around the back side of the peninsula to electrically isolate the cavity; a printed circuit board assembly (PCBA) including: an antenna front end circuit operatively coupled to the speaker grill to excite the speaker grill and dynamically switch frequencies based on the target frequency to be emitted by the speaker grill platform antenna; and a contact pin directly coupling an excitation signal to excite the speaker grill platform antenna.

A sound transmission device includes a main body, a first magnetic member, and a cover assembly. The main body includes a sound transmission opening. The first magnetic member is fixed to the main body and is adjacent to the sound transmission opening. The cover assembly includes an outer cover, a second magnetic member, and a fixing member. The second magnetic member is fixed between the outer cover and the fixing member. The cover assembly is magnetically attached to the first magnetic member through the second magnetic member, so that the outer cover covers the sound transmission opening. The outer cover includes a through hole, and the through hole is in communication with the sound transmission opening.

Disclosed is a micro-filter comprising a substrate with a back cavity and a film layer provided on the substrate and suspended above the back cavity; the film layer has through holes distributed thereon, and is made of an amorphous metal film. Also disclosed is an acoustic device comprising the micro-filter.

An acoustic device comprises a shell and a sound producing assembly, the shell being provided with an installation hole and a sound outlet, and the sound producing assembly being fixed inside the shell. The sound producing assembly has a diaphragm separating a cavity of the acoustic device into a front cavity and a back cavity, a first part of the shell corresponding to the front cavity and/or a second part of the shell corresponding to the back cavity is provided with sapphire glass covering the installation hole, and the front cavity is in communication with the outside of the acoustic device through the sound outlet.

This present disclosure provides an acoustic device. The acoustic device includes a housing, one or more sound pickup assemblies, and one or more channel assemblies. The housing has an accommodating space and one or more communication holes. Each communication hole communicates the accommodating space and an outside space. The one or more sound pickup assemblies may be disposed in the accommodating space for picking up a sound through the communication holes. The one or more channel assemblies may be disposed in the accommodating space. At least one of the one or more channel assemblies is disposed between one sound pickup assembly of the one or more pickup assemblies and one communication hole of the one or more communication holes, so that the sound is transmitted to the sound pickup assembly through the at least one of the one or more channel assemblies after passing through the communication hole.

A sound transducer device includes a multilayer component board having a first side and an opposite second side, and a sound port extending between the first and second sides of the multilayer component board. The sound transducer also includes a MEMS sound transducer die including a suspended membrane structure, wherein the MEMS sound transducer die is arranged at the first side of the multilayer component board such that the suspended membrane structure is in fluid communication with the sound port. The sound transducer also includes a mesh structure for providing an environmental barrier, the mesh structure covering the sound port from either one of the first and second sides of the multilayer component board.
