  • Patent number: 10869115
    Abstract: Embodiments of the present disclosure generally relate to custom-fit in-ear audio devices, also referred to herein as in-ear audio devices, custom-fit earpieces, or simply earpieces. The following discloses embodiments of custom-fit earpieces that include features providing superior retention in a user's ear while also maintaining desirable comfort and sound quality. The superior retention is generally provided by a curable filler material disposed in a sleeve body that is deformed to conform to the shape of a user's ear as the curable filler material is cured. The comfort level of the custom-fit earpiece described herein is enhanced because the audio output member can move independently or relative to the portion of the earpiece that includes the curable filler material, thus allowing the audio output member to adjust to and comfortably fit within a given user's ear canal.

  • Patent number: 10856085
    Abstract: A microphone and its manufacturing method, relating to semiconductor techniques. The microphone comprises a substrate with a back through-hole going through the substrate; a first electrode layer on the substrate covering the back through-hole; a back plate on the substrate, wherein the back plate and the first electrode layer form a cavity, and the first electrode layer comprises a gap connecting the back through-hole and the cavity; and a second electrode layer in the cavity and on a bottom surface of the back plate. In this inventive concept, the gap in the first electrode layer increases the sensitivity of the first electrode layer and thus improves the Signal-to-Noise Ratio (SNR).

  • Patent number: 10848844
    Abstract: A method of installing a ceiling speaker system includes inserting a top end portion of an enclosure of a speaker system into a hole in a ceiling such that a spring-loaded tab of the speaker system is caused to pivot about a pivot axis as the spring-loaded tab comes into contact with an edge of the hole. The top end portion of the enclosure is moved upward, through the hole until the spring-loaded tab is clear of the hole. A lead screw of the speaker system is rotated about its longitudinal axis to cause the spring-loaded tab to be displaced toward a flange arranged along a bottom end portion of the speaker system, and thereby clamping the ceiling between the flange and the spring-loaded tab. The longitudinal axis of the lead screw is coincident with the pivot axis of the spring-loaded tab.

  • Patent number: 10841702
    Abstract: A BGM signal of sound of BGM is outputted over time, and a sound effect signal of sound of a sound effect is outputted at a timing determined based on information processing. If it is determined that a sound intensity at a predetermined frequency component of the sound effect to be outputted is low or a sound intensity at the predetermined frequency component of the BGM is high, adjustment is performed such that the sound intensity at the predetermined frequency component of the BGM to be outputted at the same timing as the sound effect is decreased. Then, a final sound signal including the sound of the sound effect and the sound of the BGM on which the adjustment has been performed, is synthesized and outputted.
