Abstract

An earset communication device capable of reliably suppressing transmission of microvibration to a microphone part. The earset communication device of the present invention is an earset communication device 1 attached to a human ear, which has a main body 2, a sound guide part 3 where a sound guide housing 3a protruding from the main body 2 is attached to the cavum conchae 61, and a microphone part 4 where a microphone housing 4a protruding from the main body 2 in continuously to the sound guide housing 3a in a fork shape is inserted into the cavum conchae in contact therewith. The main body 2 has a speaker 11. The sound guide part 3 has a sound guide tube 12 for guiding the sound output from the speaker 11 to the cavum conchae 61 in the sound guide housing 3a. The microphone part 4 has a bone conduction microphone 30 in the microphone housing 4a.

Claims

1. An earset communication device attached to a human ear, comprising:

a main body having a sound output unit outputting sound inside;

a sound guide part protruding from the main body, attached to a cavum conchae of the ear, and guiding the sound output from the sound output unit to the cavum conchae; and

a microphone part protruding from the main body, inserted into the cavum conchae in contact therewith, and having a bone conduction sound detection unit detecting bone conduction sound transmitted to the cavum conchae.

2. The earset communication device of claim 1 wherein the microphone part protrudes from the main body in continuously to the sound guide part in a fork shape.

3. The earset communication device of claim 1, wherein the sound guide part has a sound guide tube guiding the sound output from the sound output unit to the cavum conchae.

4. The earset communication device of claim 3, wherein the sound guide part has a switch unit switching a direction of a guiding path through which the sound guide tube guides the sound.

5. The earset communication device of claim 4, wherein the sound guide part has a fixing unit fixing a direction of the guiding path.

6. The earset communication device of claim 1, wherein the microphone part is rotatably connected to the main part.

7. The earset communication device of claim 1, wherein the sound output unit is fixed to a substrate where an electronic component is mounted.

8. The earset communication device of claim 7, wherein a battery is mounted to the substrate.

9. The earset communication device of one of claims 1 to 8, wherein the main body has a communication circuit and an antenna for radio communication with a separated base unit.

10. An earset communication device attached to a human ear, comprising:

a main body;

an earphone part protruding from the main body, attached to a cavum conchae of the ear, and outputting sound to the cavum conchae; and

a microphone part protruding from the main body, inserted into the cavum conchae in contact therewith, and having a bone conduction sound detection unit detecting bone conduction sound transmitted to the cavum conchae,

wherein the microphone part is rotatably connected to the main body.

11. The earset communication device of claim 10, wherein the microphone part protrudes from the main body in continuously to the earphone part in a fork shape.

12. The earset communication device of claim 10, further comprising a stopper restricting rotation of the microphone part.

13. An earset communication device attached to a human ear, comprising:

a main body having an electronic circuit substrate for radio communication;

an earphone part protruding from the main body, attached to a cavum conchae of the ear, and outputting sound to the cavum conchae; and

a microphone part protruding from the main body, inserted into the cavum conchae in contact therewith, and detecting bone conduction sound transmitted to the cavum conchae.

14. The earset communication device of claim 13, wherein the main body further comprises a battery supplying power to the electronic circuit substrate, and the battery is placed between the electronic circuit substrate and a head of a user in a state where the communication device is attached to the user.

15. The earset communication device of claim 13, wherein the main body further comprises a speaker, and the speaker is fixed to the electronic circuit substrate through attenuating material.

19. The earset communication device of one of claims 14 to 18, wherein the battery is housed in a lower part of the main body in a state where the communication device is attached to a user.

16. An earset communication device attached to a human ear, comprising:

a main body having an antenna for radio communication;

an earphone part protruding from the main body, attached to a cavum conchae of the ear, and outputting sound to the cavum conchae; and

a microphone part protruding from the main body, inserted into the cavum conchae in contact therewith, and detecting bone conduction sound transmitted to the cavum conchae.

17. The earset communication device of claim 16, wherein the main body comprises a housing, and the antenna is placed in the housing located apart from a head of a user in a state where the communication device is attached to the user.

18. The earset communication device of claim 16, wherein the main body further comprises a battery, and the battery is placed between the antenna and a head of a user in a state where the communication device is attached to the user.
