Abstract

A method and apparatus for providing a user-selectable sound profile for a telecommunications device, wherein the user may select at least one available frequency response profile to be applied to an audio signal by a digital equalizer.

Claims

1. A telecommunications device comprising:

a receiver for receiving a telecommunications signal;

a processor for converting the telecommunications signal into an audio signal;

a storage medium for storing at least one frequency response profile;

selection means for selecting the at least one frequency response profile;

equalizer means for applying the at least one frequency response profile to the audio signal to produce an equalized audio signal; and

a speaker for playing back the equalized audio signal.

2. The telecommunications device of claim 1 wherein the telecommunications device is a cordless telephone.

3. The telecommunications device of claim 1 wherein the telecommunications device is a handsfree speakerphone.

4. The telecommunications device of claim 1 wherein the at least one frequency response profile produces an equalized audio signal that complies with one of:

TIA 470B, TIA 470C, and FCC Part 68.316 HAC.

5. The telecommunications device of claim 1 wherein the telecommunications device further comprises audio profile adjustment means by which the user may adjust the frequency response profile characteristics.

6. A method for adjusting the audible frequency response of a telecommunications device, comprising the steps of:

receiving a signal;

extracting an audio signal from the received signal;

providing parameter defining at least one frequency response profile stored in a storage medium;

selecting one of the at least one frequency response profiles to be applied to the audio signal;

applying the selected frequency response profile to the audio signal to produce an equalized audio signal; and

playing the equalized audio signal through a speaker.

7. The method of claim 6 wherein the step of providing parameter defining at least one frequency response profile stored in a storage medium further comprises the step of providing a Bass Boost profile, a Treble Boost profile, a Mid Boost profile and a Natural Boost profile.

8. The method of claim 6 wherein the equalized audio signal complies with one of:

TIA 470B, TIA 470C and FCC Part 68.316 HAC.

9. The method of claim 6 wherein the equalized audio signal complies with a recognized telecommunication standard.

10. A telecommunications device comprising:

a telephone line interface means for receiving a telecommunications signal;

a processor to control the routing of the telecommunications signal;

a storage medium for storing at least one frequency response profile;

selection means for selecting the at least one frequency response profile;

equalizer means for dynamically applying a frequency response profile to the audio signal to produce an equalized audio signal; and

a speaker for playing back the equalized audio signal.
