Abstract

A communication device includes a body and a sound receiving device. One end of the sound receiving device is pivotally connected to the body. The sound receiving device includes an omni-directional microphone and a uni-directional microphone. A processor has two modes for starting and operating the omni-directional microphone and the unidirectional microphone, respectively. An angle detecting element is located at the body to measure a rotary angle of the sound receiving device relative to the body, and then the processor switches to one of the two modes according to the rotary angle further to start the omni-directional microphone or the unidirectional microphone.

Claims

1. A communication device comprising:

a body;

a sound receiving device one end of which is pivotally connected to the body, wherein the sound receiving device comprises an omni-directional microphone and a uni-directional microphone;

a processor having two modes for starting and operating the omni-directional microphone and the uni-directional microphone, respectively; and

an angle detecting element which is located at the body and is used for measuring a rotary angle of the sound receiving device relative to the body to allow the processor to switch to one of the two modes according to the rotary angle further to start the omni-directional microphone or the uni-directional microphone.

2. The communication device according to claim 1, wherein when the sound receiving device is attached to the body, the rotary angle is zero degrees, and the processor starts the omni-directional microphone.

3. The communication device according to claim 1, wherein when the sound receiving device is rotated to be away from the body, the processor starts the uni-directional microphone.

4. The communication device according to claim 1, wherein when the sound receiving device is approximately perpendicular to the body, that is, the rotary angle is seventy degrees to one hundred and ten degrees, the processor switches to the mode of operating the uni-directional microphone.

5. The communication device according to claim 1, wherein the angle detecting element is located at a position where the body is pivotally connected to the sound receiving device.

6. A communication device comprising:

a body;

a sound receiving device one end of which is pivotally connected to the body, wherein the sound receiving device comprises an omni-directional microphone, a uni-directional microphone and a first angle detecting element;

a processor having two modes for starting and operating the omni-directional microphone and the uni-directional microphone, respectively; and

a second angle detecting element which is located at the body, wherein the first angle detecting element and the second angle detecting element are used for measuring a rotary angle of the sound receiving device relative to the body to allow the processor to switch to one of the two modes further to start the omni-directional microphone or the uni-directional microphone.

7. The communication device according to claim 6, wherein the first angle detecting element is a magnetic element, and the second angle detecting element is a magnetism sensing element.

8. The communication device according to claim 7, wherein the magnetism sensing element is a Hall effect sensor.

9. The communication device according to claim 6, wherein the first angle detecting element is a magnetism sensing element, and the second angle detecting element is a magnetic element.

10. The communication device according to claim 9, wherein the magnetism sensing element is a Hall effect sensor.

11. The communication device according to claim 6, wherein when the sound receiving device is attached to the body, the rotary angle is zero degrees, and the processor starts the omni-directional microphone.

12. The communication device according to claim 6, wherein when the sound receiving device is rotated to be away from the body, the processor starts the uni-directional microphone.

13. The communication device according to claim 6, wherein when the sound receiving device is approximately perpendicular to the body, that is, the rotary angle is seventy degrees to one hundred and ten degrees, the processor switches to the mode of operating the uni-directional microphone.

14. The communication device according to claim 6, wherein the second angle detecting element is located at a position where the body is pivotally connected to the sound receiving device.

15. The communication device according to claim 6, wherein the first angle detecting element is located at one end where the body is pivotally connected to the sound receiving device.

16. The communication device according to claim 6, wherein the first angle detecting element is located at another end opposite to the end where the body is pivotally connected to the sound receiving device.
