Abstract: An apparatus including a housing member and an airflow spreader. The housing member includes an acoustic back cavity for a sound transducer and at least two second cavities in the housing member spaced from the acoustic back cavity. The airflow spreader is connected to the housing member. The airflow spreader includes a conduit system connecting the acoustic back cavity directly with each of the at least two second cavities through the airflow spreader.

Abstract: An apparatus comprising: at least one speaker; and at least one microphone, wherein there is an acoustic coupling between the at least one speaker and the at least one microphone; at least one location defined by the at least one acoustic coupling between the apparatus at least one speaker and the apparatus at least one microphone; and at least one dampening element at the determined location, such that the at least one acoustic coupling between the at least one speaker and the at least one microphone is substantially reduced.

Abstract: An apparatus comprising: a resonance module located within a resonator frame, the resonance module comprising at least two integrated conductive suspension parts, the at least two integrated conductive suspension parts being configured to couple the resonance module to the frame, and further configured to provide a current through the resonance module, wherein the at least two integrated conductive suspension parts enable the resonance module to resonate.

Abstract: An apparatus including a frame; a coil movably connected to the frame; and a magnet system connected to the frame. The magnet system includes at least one magnet and at least one pole piece connected to the at least one magnet. The at least one pole piece include a magnet pot. A cross sectional length of the magnet pot and the frame are substantially the same in at least one cross sectional location.

Abstract: An apparatus (10) comprising: an audio transducer (201) configured to at least one of: generate sound upon receiving an audio signal provided by the apparatus (10); and convert sound into an audio signal to be processed by the apparatus (10); a housing component (301) comprising one or more sound apertures (303) configured to allow the transmission of sound through the one or more sound apertures (303); and an acoustic cavity (203) inside the apparatus (10) being acoustically coupled to the audio transducer (201) using the one or more sound apertures (303) wherein the one or more sound apertures (303) are configured to provide an acoustic damping.

Abstract: An apparatus including a housing member and an airflow spreader. The housing member includes an acoustic back cavity for a sound transducer and at least two second cavities in the housing member spaced from the acoustic back cavity. The air-flow spreader is connected to the housing member. The airflow spreader includes a conduit system connecting the acoustic back cavity directly with each of the at least two second cavities through the airflow spreader.
