    Abstract: A speaker apparatus is provided in order to both receive and dissipate heat and to provide acoustic absorption for sound waves propagating through a speaker cavity. The speaker apparatus includes a speaker and a speaker cavity configured to receive sound waves emitted by the speaker for propagation through the speaker cavity. The speaker apparatus also includes a heat dissipation structure disposed at least partially within the speaker cavity. The heat dissipation structure includes a heat pipe or a heat sink configured to receive heat from a component that generates heat. The heat dissipation structure is configured to provide acoustic absorption for the sound waves propagating through the speaker cavity.

    Abstract: A system, apparatus, method and computer program product determine the location of a receiver, such as one or more sensors, carried by a device, e.g., a robot. In a method, an audio signal is received in response to a predetermined audio signal provided by at least two audio source devices. For the audio signal that is received from a respective audio source device, the method estimates a first impulse response between the respective audio source device and the receiver. For the first impulse response estimated between each respective audio source device of the at least two audio source devices and the receiver, the method removes one or more reflections from the first impulse response to create direct path information. The method also includes determining a location of the receiver based at least in part upon the direct path information.

    Abstract: A method, apparatus and computer program product enhance audio quality during a voice communication session, enhancing audio quality for a device of a remote user. The apparatus can comprise a processor, a memory, and a computer program code, and can be configured to receive and weight audio signals based on signal attributes such that audio signals can be adjusted and adjusted signals mixed to form a composite audio signal. In a method, a processor receives audio signals from audio sensors around a room, selects one or more audio signals based on audio signal attributes, and adjusts or causes the adjustment of the one or more audio signals based on the audio signal attributes. The method can also include causing the adjusted audio signals to be mixed to form a composite signal, and causing the composite signal to be communicated to a device of a remote user.

    Abstract: A speaker apparatus is provided in order to both receive and dissipate heat and to provide acoustic absorption for sound waves propagating through a speaker cavity. The speaker apparatus includes a speaker and a speaker cavity configured to receive sound waves emitted by the speaker for propagation through the speaker cavity. The speaker apparatus also includes a heat dissipation structure disposed at least partially within the speaker cavity. The heat dissipation structure includes a thermally conductive mesh that at least partially fills the speaker cavity. The heat dissipation structure further includes an active element configured to direct heat generated by a component into the thermally conductive mesh for dissipation therein. The thermally conductive mesh is configured to provide acoustic absorption for the sound waves propagating through the speaker cavity.
