Abstract
An equalized hearing aid system includes a microphone, a first equalizer, a first mixer, and a first speaker coupled in series forming a first signal path with a second mixer coupled to the first equalizer within the first signal path. The microphone, a second equalizer, a third mixer, and a second speaker are coupled in series forming a second signal path with a fourth mixer coupled to the second equalizer within the second signal path. A control interface may be coupled to at least one of the first equalizer and the second equalizer. A Bluetooth module may be coupled to at least one of the first equalizer and the second equalizer. A third equalizer may be coupled to input signal into the first signal path and a fourth equalizer may be coupled to input signal into the second signal path.
Claims11
A hearing aid system comprising:
- a microphone, a first variable gain amplifier, a first mixer, and a first speaker coupled in series forming a first signal path;
- a Bluetooth module configured to receive signals from another Bluetooth enabled device or to transmit signals to the another Bluetooth enabled device;
- another microphone coupled to the Bluetooth module for transmitting signals received from the another microphone to the another Bluetooth enabled device;
- and
- a second mixer coupled in series between the first variable gain amplifier and the first mixer, wherein the Bluetooth module is coupled to the second mixer to transmit audio signals received from the another Bluetooth enabled device to the second mixer;
- wherein the first mixer is configured to optionally receive a first signal from the first variable gain amplifier or a second signal from a first auxiliary input for output to the first speaker, or combine the first and second signals to output the combined signal to the first speaker.
A hearing aid system comprising:
- a microphone, a first variable gain amplifier, a first mixer, and a first speaker coupled in series forming a first signal path, wherein the first mixer is configured to optionally receive signal from the first variable gain amplifier or signal from a first auxiliary input for output to the first speaker, or combine the received signals to output the combined signal to the first speaker;
- a Bluetooth module configured to receive signals from another Bluetooth enabled device or to transmit signals to the another Bluetooth enabled device, the Bluetooth module coupled to the first variable gain amplifier and is further configured to transmit control signals received from the another Bluetooth enabled device to the first variable gain amplifier for controlling the first variable gain amplifier;
- and
- a second mixer coupled in series between the first variable gain amplifier and the first mixer, wherein the Bluetooth module is coupled to the second mixer to transmit audio signals received from the another Bluetooth enabled device to the second mixer.
