Abstract: A waterproof speaker module may include a membrane formed from at least one waterproof and elastic material and a supporting structure. The membrane may include an outer surface, an inner surface, and at least one concave region that is indented toward the inner surface. The supporting structure may be coupled to the membrane and include a support structure that mates with the concave region of the membrane when the speaker is subjected to a hydrostatic load. When the speaker is not subjected to a hydrostatic load, the support structure may contact the concave region. In this way, the membrane may be resistant to tearing or rupture due to hydrostatic load.

Abstract: A mobile electronic device including a processor, a first electrical component including at least one contact area, and a second electrical component including at least one contact arm extending over a top surface of the second electrical component and secured in at least two locations, the at least one contact arm configured to be in electrical communication with the at least one contact area. In another embodiment, the electronic device further includes a microphone operably connected to an enclosure. A first resilient member coupled to the enclosure and a first side of the microphone and a second resilient member coupled to a second side of the microphone and a support structure within the enclosure.

Abstract: Electronic devices and equipment may communicate over a wired communications path. The wired communications path may include one or more wires and may be associated with a headphone cable. Data may be conveyed in the form of a digital data stream containing multiple traffic channels. The digital data stream may include superframes, each of which has multiple frames of data. The frames of data may each contain a number of data slots. Some of the slots in a superframe may be used exclusively by a particular one of the traffic channels. Boundary slots may be shared between traffic channels. Data interface circuitry may implement a data dispersion algorithm that determines the pattern in which data from each traffic channel is distributed within each boundary slot. Transmitting data interface circuitry may merge traffic channels into a single data stream. Receiving data interface circuitry may reconstruct the traffic channels.

Abstract: Radio terminal equipment of a communication system, the communication system comprising one or more secondary units coupled to the radio terminal equipment, the radio terminal equipment comprising: means for receiving information on audio characteristics optimising an audio signal of the secondary unit, means for converting the audio characteristics information into a form of an audio control algorithm used in the radio terminal equipment for performing a secondary unit audio control algorithm, means for optimising an audio signal of the secondary unit by using the secondary unit audio control algorithm.

Abstract: Loudspeakers can be damaged by high drive signals. One reason for this damage is an excess vibration displacement of the coil-diaphragm assembly. This invention describes a novel method for limiting this displacement by a signal processor. In the present invention, a low frequency shelving and notch filter is used to attenuate low frequencies according to a prediction of the loudspeaker displacement. A novel method for calculating coefficient values for a digital implementation of the low frequency shelving and notch filter according to the predicted displacement is described.
