Hearing aid communication system and hearing aid communication method thereof

1. A hearing aid communication system, used for allowing a hearing aid to receive a sound signal from a sound-providing apparatus, wherein the sound-providing apparatus has a digital signal transmitting port, the hearing aid communication system comprising:

a digital signal receiving port, electrically connected to the digital signal transmitting port of the sound-providing apparatus, used for receiving a sound signal from the sound-providing apparatus;

a wireless transmission module, used for connecting to the hearing aid via a wireless communication path; and

a processing module, electrically connected to the digital signal receiving port and the wireless transmission module, used for determining whether the sound-providing apparatus is providing the sound signal, wherein when the sound-providing apparatus is providing the sound signal, the processing module controls the wireless transmission module to establish a connection with the hearing aid; when the processing module determines that the hearing aid cannot receive a digital sound signal from the sound-providing apparatus, the processing module controls the wireless transmission module to break the connection with the hearing aid.

2. The hearing aid communication system as claimed in claim 1 , wherein when the sound-providing apparatus stops providing a sound signal, the reason is that the sound-providing apparatus provides silence for a specific length of time; thus, the processing module controls the wireless transmission module to break the connection with the hearing aid.

3. The hearing aid communication system as claimed in claim 1 , the hearing aid communication system further comprising a decoding module electrically connected to the digital signal receiving port and used for decoding the sound signal into an uncompressed digital sound signal format.

4. The hearing aid communication system as claimed in claim 1 , wherein when the sound-providing apparatus is providing the sound signal continuously, the processing module controls the wireless transmission module to maintain the connection with the hearing aid.

5. The hearing aid communication system as claimed in claim 1 , wherein the wireless transmission module connects to the hearing aid via a Bluetooth protocol.

6. The hearing aid communication system as claimed in claim 1 , wherein the digital signal transmitting port and the digital signal receiving port are S/PDIF ports.

7. A hearing aid communication method, used for allowing a hearing aid to receive a sound signal from a sound-providing apparatus, the method comprising:

determining whether the sound-providing apparatus is providing a sound signal;

when the sound-providing apparatus is providing the digital sound signal, establishing a connection with the hearing aid;

receiving the sound signal from the sound-providing apparatus for transmission to the hearing aid; and

when the hearing aid cannot receive a digital sound signal from the sound-providing apparatus, breaking the connection with the hearing aid.

8. The hearing aid communication method as claimed in claim 7 , wherein the step of stopping providing the sound signal from the sound-providing apparatus further comprises:

determining that the sound-providing apparatus has provided silence for a specific length of time; and

controlling the wireless transmission module to break the connection with the hearing aid.

9. The hearing aid communication method as claimed in claim 7 , further comprising a step of decoding the sound signal into an uncompressed digital sound signal format.

10. The hearing aid communication method as claimed in claim 7 , further comprising a step of maintaining the connection with the hearing aid when the sound-providing apparatus is providing the sound signal continuously.

11. The hearing aid communication method as claimed in claim 7 , further comprising a step of connecting to the hearing aid via a Bluetooth protocol.
