Abstract

A hearing aid device includes a signal transforming unit for converting an analog sound signal received by a signal receiving unit to a digital signal; a memory unit for temporarily storing the digital signal; a sound processing module for reprocessing the sound signal stored in the memory unit via a microprocessing unit according to parameters set by a user; a sound control module for receiving the sound signal processed by the sound processing module and adjusting an output volume via the microprocessing unit; and a signal output unit for receiving and outputting the sound signal adjusted by the sound control module. By such arrangement, a speed, tone and/or volume of an output sound can be controlled using the hearing aid device to thereby help the user to receive and recognize the sound signal.

Claims

1. A hearing aid device comprising:

a signal receiving unit for receiving an external analog sound signal for the hearing aid device;

a signal transforming unit for converting the analog sound signal received by the signal receiving unit to a digital sound signal;

a memory unit for temporarily storing the digital sound signal converted by the signal transforming unit and other digital signals processed by other units and modules of the hearing aid device;

a sound processing module for reprocessing the sound signal stored in the memory unit via a microprocessing unit of the hearing aid device according to parameters set by a user;

a sound control module for receiving the sound signal processed by the sound processing module and adjusting an output volume of the sound signal via the microprocessing unit; and

a signal output unit for receiving and outputting the sound signal adjusted by the sound control module.

2. The hearing aid device of claim 1, further comprising an input unit for the user to enter data and/or commands for operating and controlling the hearing aid device.

3. The hearing aid device of claim 1, further comprising a data transmitting unit for connecting the hearing aid device to an external device via a wireless or wired connection, so as to allow signal data to be transmitted or received between or by the hearing aid device and the external device.

4. The hearing aid device of claim 3, wherein the data transmitting unit is a wireless data transmitting interface selected from the group consisting of radio frequency transmitting interface, infrared transmitting interface, and bluetooth transmitting interface.

5. The hearing aid device of claim 3, wherein the data transmitting unit is a wired data transmitting interface selected from the group consisting of universal serial bus (USB) and IEEE (Institute of Electrical and Electronics Engineers) 1394.

6. The hearing aid device of claim 1, wherein the signal receiving unit is a microphone.

7. The hearing aid device of claim 1, wherein the signal transforming unit is an analog-to-digital or digital-to-analog signal converter.

8. The hearing aid device of claim 1, wherein the memory unit is one selected from the group consisting of static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), and double data rate SDRAM (DDRSDRAM).

9. The hearing aid device of claim 1, wherein the sound processing module adjusts a speed or tone of an output sound according to the user'"'"'s setting.

10. The hearing aid device of claim 1, wherein the signal output unit is a loudspeaker.

11. The hearing aid device of claim 1, further comprising a non-volatile storage unit and a test to speech (TTS) system, for converting received recognizable analog voice data to digital voice data and translating the digital voice data to corresponding digital voice data of other languages.
