摘要： A loudspeaker grille comprises a carrier element, which comprises a plurality of openings through a front surface, and a cover element to be attached to the front surface, which comprises a plurality of openings corresponding to the openings of the carrier element. The cover element is attached to the carrier front surface, wherein the cover element covers at least part of the front surface of the carrier element, and wherein the openings of the carrier element and the cover element are aligned with each other. The cover element is made of a flexible organic material, in particular a compound material with an organic outer surface layer, such as cork-leather.

摘要： A loudspeaker diaphragm (12) comprising a woven fibre body supports damping material (25), for example PVA polymer, on a rearward-facing surface (24). The woven fibre body may be formed of lengths (14) non-metallic fibre material (for example glass fibre) coating with a thin metal coating (32). The mass of the layer of damping material (25) may be less than the mass of the woven fibre body. An attractive sparkly looking loudspeaker diaphragm (12) may thus be provided which damps undesirable vibration whilst providing a flatter frequency-response curve (50).

摘要： A venting device includes an anchor structure and a membrane. The membrane is anchored on the anchor structure and configured to form a first vent and a second vent. The membrane includes a first flap, a second flap and a third flap. The membrane partitions a space into a first volume and a second volume, and the first volume and the second volume are connected when the first vent and the second vent are formed. The first flap is actuated to move toward a first direction and the second flap is actuated to move toward a second direction opposite to the first direction, so as to form the first vent. The first flap is actuated to move toward the first direction and the third flap is actuated to move toward the second direction opposite to the first direction, so as to form the second vent.

摘要： Method and devices for processing audio signals based on sound profiles are provided. A sound profile can include data related to haptic movement of the audio data which is specific to a left ear or a right ear, demographic information, ethnicity information, age information, location information, social media information, intensity score of the audio data, previous usage information, or device information. A sound profile can be customized for individual user to include the inaudible frequency range at high frequency end and low frequency end. Audio data within the inaudible frequency range can be compensated by haptic movement corresponding to the inaudible frequency range. A sound profile can further include an audio frequency range and its lowest audible volume for a user. A sound profile can be provided to a user without any action from the user's part.
