Hearing aid having an audio signal generator and method
First Claim
1. A hearing aid, comprising:
- a sound receiver responsive to sound waves to generate a microphone signal based on the sound waves;
a transmitting unit coupled to receive the microphone signal from the sound receiver and generate a power signal based on the microphone signal;
a sound generator coupled to receive at least the power signal from the transmitting unit and generate a sound based on the power signal, the sound generated by the sound generator effective to be perceived by an auditory organ of a user of the hearing device; and
an audio signal unit comprising;
a memory coupled to store at least one generation parameter;
a tone signal generator coupled to the memory to generate a tone signal in response to a trigger signal and as a function of said at least one generation parameter; and
a central control unit responsive to a signal indicative of a predefined sound event related to the hearing aid to generate the trigger signal,wherein the audio signal unit is coupled to the sound generator to transmit the tone signal to the sound generator, wherein the tone signal is configured to produce a further sound indicative of an occurrence of the defined event and effective to be perceived by the auditory organ of the user of the hearing device.

Abstract
The invention relates to a hearing aid having a sound receiver and a sound generator. The hearing aid also has an audio signal unit that is functionally linked to the sound generator and has a tone signal generator for generating a tone signal as a function of a trigger signal and of a generation parameter which represents a frequency that can be perceived by a human ear. The hearing aid also has a memory, connected to the tone signal generator, for storing the generation parameter. The audio signal unit changes the generation parameter stored in the memory, generates a trigger signal for each tone signal requiring to be generated, sends said trigger signal to the tone signal generator, and sends the generated tone signal to the sound generator.

10. A method for generating a tone signal by a hearing aid, comprising:
-
generating a microphone signal based on sound waves received by a sound receiver; generating in a transmitting unit a power signal based on the microphone signal; generating in a sound generator a sound based on the power signal, the sound generated by the sound generator effective to be perceived by an auditory organ of a user of the hearing device; and arranging in the audio signal unit at least a memory, a tone signal generator and a central control unit storing at least one generation parameter in the memory; generating a tone signal in the tone signal generator in response to a trigger signal and as a function of said at least one generation parameter; generating the trigger signal in the central control unit in response to a signal indicative of a predefined sound event related to the hearing aid; and coupling the audio signal unit to the sound generator to transmit the tone signal to the sound generator, wherein the tone signal is configured to produce a further sound indicative of an occurrence of the defined event and effective to be perceived by the auditory organ of the user of the hearing device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
