Abstract

An environmental sensor distinguishes between a plurality of different ambient acoustic environments and communicates with an audio gain circuit which automatically adjusts the audio characteristics of the speaker and microphone of a wireless communications assembly for more optimum audio performance. The wireless communications assembly preferably includes a hands free adapter coupled to a wireless communications device such as a cellular telephone. The adjustments to the audio characteristics are according to predetermined settings for the identified ambient acoustic environment which are preferably stored in memory associated with the audio gain circuit. In this manner, the audio characteristics are automatically adjusted for the actual ambient acoustic environment that the wireless communications assembly is operating in.

Dependent claims

A wireless communications assembly, comprising:

a) an environmental sensor for distinguishing between a plurality of different ambient acoustic environments;
b) an audio gain circuit in communication with said environmental sensor;
c) a hands free circuit in communication with said audio gain circuit;
d) a speaker in communication with said audio gain circuit;
e) a microphone in communication with said audio gain circuit;
f) wherein said audio gain circuit adjusts the audio characteristics of at least one of said microphone and said speaker depending on the ambient acoustic environment detected by said environmental sensor;
g) a hands free adapter including said environmental sensor;
h) a wireless communications device coupled to said hands free adapter, wherein the ambient acoustic environment detected by said environmental sensor is communicated to said wireless communications device, said wireless communications device changing operating modes depending on the ambient acoustic environment detected by said environmental sensor;
and
i) wherein said wireless communications device includes a plurality of groups of stored phone numbers and wherein the availability of said groups depends on the ambient acoustic environment detected by said environmental sensor.
