摘要:
According to one aspect, an electronic device for detecting an audio accessory. The electronic device includes an audio jack having at least two detection terminals. The detection terminals are spaced apart and positioned within a socket of the audio jack so when an audio plug of the accessory is inserted into the socket of the audio jack, the detection terminals will be shorted. The presence of a short between the detection terminals is indicative that the audio accessory is present.

A method of providing a user interface on a mobile device for enabling a user to select acoustic equalizer settings for voice call downlink audio signals, the mobile device including an internal microprocessor, a display in communication with the microprocessor, and at least one input means in communication with the microprocessor, the method including receiving a request from the user for displaying the user interface, in response to the request, displaying the user interface on the display, the user interface including a plurality of predetermined acoustic equalizer settings, wherein the user selects one of the equalizer settings using the input means, receiving the selected equalizer setting at the microprocessor, storing the selected equalizer setting at the microprocessor, and processing the voice call downlink audio signals according to the selected equalizer setting.
摘要:
An apparatus, and an associated method, provides for operation of a handset receiver at a volumetric output level of either a hands free mode of operation or a handset mode of operation. A noncontact proximity sensor detects proximity of the handset to a user. If the sensed proximity indicates that the handset is positioned proximate to the user, the maximum volumetric output level is constrained to be no greater than a maximum handset mode of operation level. If the sensed proximity is greater than a minimum distance, high volumetric output levels are permitted of the handset receiver.
摘要:
Dual microphones can be used to improve noise suppression by better distinguishing between speech and background noise. If the user does not hold the handset according to a prescribed orientation, however, the dual microphone noise suppression can actually do a worse job than a single microphone noise suppression algorithm because of mistakes made distinguishing between speech and noise. Here it is proposed to use an accelerometer to determine the orientation of the phone and use this orientation information in the noise suppression algorithm. Also when a person speaks, the vibrations when the device is held against the head can be used to detect speech.

摘要:
A user is allowed to select an acoustic equalizer setting from among a plurality of predetermined acoustic equalizer settings. Upon receiving an indication of a selection of a given acoustic equalizer setting, a handheld telephony device processes voice call downlink audio, based on the given acoustic equalizer setting and drives an audio output device with the processed audio signal.
