Embodiments of the present invention are capable of determining a face direction associated with a detected subject (or multiple detected subjects) of interest within a 3D space using face detection procedures, while simultaneously avoiding the pick up of other environmental sounds. In addition, if more than one face is detected, embodiments of the present invention can automatically detect an active speaker based on the recognition of facial movements consistent with the performance of providing audio (e.g., tracking mouth movements) by those subjects whose faces were detected. Once determinations are made regarding face direction of the detected subject, embodiments of the present invention may dynamically adjust the audio acquisition capabilities of the audio capture device (e.g., microphone devices) relative to the location of the detected subject using beamforming techniques for instance. As such, embodiments of the present invention can detect the direction of the “talking object” and guide the audio subsystem to filter out any sound not coming from that direction.

A modular canal hearing aid assembly having a main module positioned in the ear canal and a disposable battery module laterally positioned in the ear canal. The main module incorporates the durable components of a hearing device including the receiver, microphone and electronics. The disposable battery module comprises consumable elements including battery and incoming sound port. The disposable battery module provides a unitary structure that is easier to handle, remove from the main module, and replace when any of the consumable elements is depleted or degraded. The canal hearing device assembly is generic in shape and provided with assorted seal tips for “instant fitting” without resorting to custom manufacturing.

The invention discloses mobile communication equipment and a volume control method thereof. The mobile communication equipment comprises a volume setting module, a volume control module and an earphone management module, wherein the volume setting module is connected with the volume control module and is used for setting the volume of different audio types in an earphone mode to be a first group of volume, and setting the volume of different audio types in a non-earphone mode to be a second group of volume; the earphone management module is connected with the volume control module and is used for detecting the earphone mode or the non-earphone mode; the volume control module is used for setting the volume of an application program to be the first group of volume in the earphone mode when the earphone mode is detected, and setting the volume of the application program to be the second group of volume in the non-earphone mode when the non-earphone mode is detected. By adopting the method, an optimum sound effect can be realized under different situations when an earphone is used or a loudspeaker is used, and hearing can be protected.
