Abstract
A headphone for use with a wireless audio device. The headphone determines whether the origin of an incoming transmission is a cell phone or a device such as a land line device or a computer. The headphone applies a different equalization pattern depending on whether the origin is a land line device or a computer or whether the origin is a cell phone. The headphone may measure the amplitude of the incoming transmission above a first threshold frequency, or below a second threshold frequency, or both to determine if the origin is a land line device or a computer or if the origin is a cell phone.
Claims16
A headphone, comprising
- a first receiver for wirelessly receiving incoming cell phone transmissions;
- a transducer for transducing the cell phone transmission to acoustic energy;
- circuitry for determining whether the origin of the cell phone transmission is a cell phone, a land line device, or a computer;
- circuitry for applying, in the event that the origin of the cell phone transmission is a cell phone, a first equalization pattern to the incoming cell phone transmission;
- and
- circuitry for applying, in the event that the origin of the cell phone transmission is a land line device or a computer, a second equalization pattern, different from the first equalization pattern, to the incoming cell phone transmission
- wherein the second equalization pattern boosts the frequencies below a threshold frequency less than the first equalization pattern.
