Abstract: Disclosed are an elastomer sleeve for a wireless earphone and a wireless earphone. The elastomer sleeve for the wireless earphone includes: a sleeve body defining a space for accommodating an earphone body of the wireless earphone; a sleeve wing portion formed integrally with the sleeve body and extending outward from the sleeve body; and an antenna formed in the elastomer sleeve and extending from the sleeve body to the sleeve wing portion. The wireless earphone includes an earphone body and one or more elastomer sleeves for detachably connecting to the earphone body and partially enclosing the earphone body.

Abstract: An example loudspeaker arrangement includes a seat configured to support a listener sitting in the seat so that a head of the listener is in a listening position; and a loudspeaker array secured to the seat and disposed in a position in front of a backrest of the seat and to the side of the head when the head is in the listening position. The loudspeaker array includes at least one loudspeaker and has a main broadcasting axis representative of a main broadcasting direction, the main broadcasting direction of the loudspeaker array pointing to the head.

Abstract: An assembly for clamping electrical components against a heat-dissipating surface of a heat sink may include the heat sink, one or more electrical components, two or more springs, and a fastener. Each of the springs may include a first surface, and a second surface opposite the first surface. The second surface of each of the springs may include an attachment region and two contact regions. The attachment region may be between the two contact regions. The second surface of one of the springs may overlap the first surface of another one of the springs. Each of the springs may be positioned to hold the electrical components against the heat dissipating surface of the heat sink. Each of the two contact regions of each of the springs may be positioned to hold the electronic components against the heat-dissipating surface. The fastener may couple the springs together in the attachment region of each of the springs and may further couple the springs to the heat sink.
