Abstract

This present disclosure relates to the speech processing technology, more specifically, to a microphone. A microphone with voice wake-up function includes a microphone body with at least one transducer for collecting sound signals, a control module and a determining module. The microphone body is performed in a sleeping mode or an operating mode through the control module in accordance with the determined result. The invention enables the microphone body to switch between the sleeping mode and the operating mode. The sleeping mode reduces unnecessary power consumption and saves electrical energy. When a certain condition is satisfied, the body of the microphone is activated from the sleeping mode and enters into the normal operating mode.

Claims

1. A microphone with voice wake-up function, said microphone comprising:

a microphone body, the microphone body comprising at least one transducer for collecting sound signal, a control module and a determining module, the signal output of the transducer is connected to the control module; and

wherein the determining module is determined in accordance with a predetermined regulation, which concludes with a determined result;

the microphone body is performed in a sleeping mode or an operating mode through the control module in accordance with the determined result.

2. The microphone with voice wake-up function as disclosed in claim 1, wherein the predetermined regulation is that whether the transducer in a predetermined time range receives the sound signal or the transformed audio signal satisfies with the predetermined condition.

3. The microphone with voice wake-up function as disclosed in claim 2, wherein when the determining module determines that the transducer in a predetermined time range receives no sound signal or the transformed audio signal does not satisfy with a predetermined condition, the control module is performed to enter into the sleeping mode.

4. The microphone with voice wake-up function as disclosed in claim 3, wherein when the determining module determines that the transformed audio signal satisfies the predetermined condition, the control module is activated from the sleeping mode and transferred into the operating mode through driving the control module via sending a driving signal.

5. The microphone with voice wake-up function as disclosed in claim 2, wherein the predetermined condition comprises a predetermined frequency range and/or an amplitude range and/or a continuous audio signal.

6. The microphone with voice wake-up function as disclosed in claim 5, wherein the frequency range is from 300 Hz to 4 KHz.

7. The microphone with voice wake-up function as disclosed in claim 2, further comprising a storage module which stores a predetermined condition.

8. The microphone with voice wake-up function as disclosed in claim 1, wherein the microphone body adopts a simulation microphone based on MEMS or an electret simulation microphone.
