Abstract:
An optical module for a display system includes a lens, a display screen, a movement mechanism, and one or more pressure-relieving features. The display screen cooperatively defines a chamber with the lens. The lens and the display screen are moved relative to each other by the movement mechanism. The one or more pressure-relieving features are in fluid communication with the chamber to hinder pressure in the chamber as the lens and the display are moved relative to each other.
Abstract:
A speaker assembly includes an enclosure having an acoustic chamber and an acoustic output opening and a speaker driver. The speaker driver includes a sound radiating surface and a first voice coil and a second voice coil positioned along opposite faces, respectively, of the sound radiating surface. The speaker driver further includes a first magnet assembly including an elongated gap in which part of the first voice coil is positioned to vibrate and a second magnet assembly having an elongated gap in which part of the second voice coil is positioned to vibrate. The first magnet assembly elongated gap is orientated lengthwise toward the acoustic chamber, and the second magnet assembly elongated gap is oriented lengthwise toward the acoustic output opening. Other embodiments are also described and claimed.
Abstract:
In one embodiment, a mobile device including a magnet unit that is thermally coupled to the heat sink portion of a housing of the mobile device is disclosed. The mobile device comprises a speaker driver that includes a magnet unit, a housing having a heat sink portion that is made of a material having a high thermal conductivity, and a thermal component. The heat sink portion has a first face that is coupled to the speaker driver and a second face that is exposed to the exterior of the mobile device. The thermal component binds the speaker driver to the first face of the heat sink portion to create a cooling path from the magnet unit to the exterior of the mobile device. Other embodiments are also described.
Abstract:
The present invention relates to a method for assembling a self-contained audio/antenna module for a portable communication device, the method comprising the steps of incorporating, into the audio/antenna module, one or more transducers, said incorporation comprising, for at least one transducer, the steps of custom designing and implementing a membrane structure for the at least one transducer in accordance with design constrains provided by an audio/antenna module casing, and incorporating a standard, prefabricated magnetic circuit into the audio/antenna module, said magnetic circuit being adapted to displace the membrane structure of the at least one transducer in accordance with incoming audio drive signals. The invention further relates to an audio/antenna module manufactured according to the above-mentioned method.
Abstract:
A speaker includes a frame, a sound radiating surface, and a suspension that couples the sound radiating surface to the frame. A horizontal former is coupled to the radiating surface. The former extends substantially horizontally outward of a peripheral portion of the radiating surface, to a peripheral portion that is separate from the suspension. A coil is coupled to the peripheral portion of the horizontal former. Other embodiments are also described and claimed.
