Abstract: An audio system including an audio device secured within a receptacle for improving voice communication is disclosed. The audio device includes a housing containing a down-firing speaker that is positioned directly above an acoustic reflector formed by surfaces associated with the bottom of the housing and a corresponding interior of the receptacle. An apex protrudes upward from the center of the receptacle toward the diaphragm of the speaker. The acoustic reflector is characterized by a curved volume extending from the apex to an outer peripheral border of the receptacle. The structural features of the audio device and receptacle are configured to significantly improve the quality of sound produced by the audio system such that it fulfills standardized wideband audio performance requirements in a compact package.

Abstract: An improved method and system for varying an amount of mechanical coupling in a speakerphone is disclosed. Solutions and implementations provided vary the amount of mechanical coupling between one or more speakers and one or more microphones of the speakerphone to generate high-quality sounds. Implementations include receiving a signal for a first speaker, transforming the signal to send to a second speaker or actuator to generate either complementary or opposing vibration forces to those generated by the first speaker, and an accelerometer to measure the amount of vibration caused by the speaker and adjust the transformation applied to the signal to increase or decrease the amount of mechanical coupling, as needed.

Abstract: An improved method and system for varying an amount of mechanical coupling in a speakerphone is disclosed. Solutions and implementations provided vary the amount of mechanical coupling between one or more speakers and one or more microphones of the speakerphone to generate high-quality sounds. Implementations include receiving an input signal, sending a copy of the input signal to a first speaker, performing a signal transformation on the input signal to produce a transformed input signal, and transmitting the transformed input signal to a second speaker, where the first speaker generates a first vibration force in response to the input signal, and the second speaker generates a second vibration force in response to the transformed input signal, the second vibration force being in an opposite direction to that of the first vibration force and offsetting at least part of the first vibration force.
