Abstract
Systems and methods of limiting peak audio power in mobile devices may include a high pass filter and a burst module to detect a burst load condition in a mobile device. The burst module can also apply the high pass filter to an audio signal of the mobile device in response to the burst load condition to obtain a filtered signal, and transmit the filtered audio signal to a speaker of the mobile device.
Claims17
A system comprising:
- an integrated hands free speaker module;
- an audio source to generate an audio signal;
- a high pass filter;
- and
- a burst module to,
- detect a burst load condition in the system,
- apply the high pass filter to the audio signal in response to the burst load condition to obtain a filtered audio signal,
- transmit the filtered audio signal to the integrated hands free speaker module,
- detect a termination of the load burst condition,
- detect a hysteresis condition, and
- remove the high pass filter from the audio signal in response to the hysteresis condition and the termination of the load burst condition.
