One or more acoustic transducers of a device may be adjusted based on automatic detection of device proximity to the user. In a mobile telephone, when the user is using the receiver and holding the telephone against his / her ear, if the telephone detects that the user has moved the telephone further from his / her ear, the telephone will raise the receiver volume. Similarly, if the user is using the speaker, the telephone will adjust the speaker volume as user distance from the telephone changes. In another embodiment the telephone may fade between the receiver and the speaker. Volume is not the only acoustic property that could be adjusted according to user proximity. Frequency response is another property that could be adjusted, such as using appropriate electronic filtering, or by turning on another transducer that is not otherwise being used.

The invention relates to a method and apparatus for producing, combining, and customizing virtual sound environments. A binaural sound system (400) includes a transceiver (492) configured for receiving a signal (600) containing at least a first type of information and a second type of information. The first type of information includes enunciated data (602). The enunciated data specifies certain information intended to be audibly enunciated to a user. The second type of information comprises first type of metadata (604-1) and a second type of metadata (604-2). The first type of metadata includes information which identifies a characteristic of the enunciated data exclusive of spatial position information. The second type of metadata identifies a spatial position information associated with the enunciated data.

The invention discloses a control method and control system of an earphone and the earphone. The control method of the earphone comprises the steps of selecting motion state judgment parameters, used for controlling the earphone,of a wearer and setting an alerting condition based on the selected motion state judgment parameters; monitoring and obtaining behavior data of the earphone wearer in real time; calculating the motion state judgment parameters by utilizing the obtained behavior data so as to obtain a motion state judgment parameter value; judging whether the motion state judgment parameter value is satisfied with the alerting condition; and if the motion state judgment parameter value is satisfied with the altering condition, determining to enter an earphone altering state and controlling to carry out corresponding alerting operations for the earphone. According to the control method of the earphone, as the current motion state of the user is judged based on the user motion state judgment parameters, and the alerting operations are taken for the earphone under the control when the motion state is satisfied with the alerting condition, the problem that the existing earphone may bring about danger to theuser in a specific occasion is solved.
