摘要:
The present document relates to media players, such as portable electronic devices, vehicle audio systems, home stereo systems, etc. In particular, it relates to the management of the sound pressure level generated by portable electronic devices. A method and system for controlling the cumulated audio dose of a user of a media player is described. The method comprises the steps of determining the audio dose already consumed by the user and of selecting one or more media tracks for play back on the media player based on the audio dose of the media track and the already consumed audio dose of the user.

The present disclosure relates to media players, such as portable electronic devices, vehicle audio systems, home stereo systems, etc. In particular, it relates to the management of the sound pressure level generated by portable electronic devices. A method and system for controlling the consumed audio dose of a user of a media player is described. The method comprises the steps of selecting a first frequency range from the total frequency range relevant for the human ear; of determining the audio dose already consumed by the user within the first frequency range; of evaluating the audio dose of a media track within the first frequency range and the already consumed audio dose of the user within the first frequency range; and of controlling the audio dose generated by the media player based on the evaluating step.

The present invention discloses a mobile electronic device, having a radio receiver (28), an amplifier (24) and an audio connector (20) for connecting to a headphone (2). Said audio connector (2) comprises at least one first contact and at least one second contact, wherein said first contact is connected to ground and to said radio receiver (28), and said second contact is connected to said amplifier (24). The electronic device is characterized by a band-pass filter component (26) interconnected between said first contact and said radio receiver (28) so that only a predefined frequency range can pass to the radio receiver, preventing cross talk interference from transmitters operated in proximity.

A circuit board in a mobile electronic device has a microphone and related amplifier and signal conditioning circuitry mounted thereon. A radio frequency (RF) shield surrounds and isolates the microphone from electromagnetic interference (EMI). The RF shield together with the circuit board forms an acoustic chamber surrounding the microphone. A hole in the RF shield permits acoustic energy to enter the acoustic chamber and reach the microphone.

A plug-and-jack for use with an electronic device that is configured to ensure circuitry of the device is protected from electrostatic discharge. In one case, the jack is an audio jack designed to protect high gain circuitry of the device against electrostatic discharge from the leads of an audio plug. The jack includes a mechanical switch that only connects the high gain circuitry to the appropriate portion of the audio plug once the audio plug is fully inserted. At the same time, the mechanical switch also connects the high gain circuitry and corresponding portion of the audio plug to an electrostatic discharge circuit.
