Headphone unit with integrated microphone

technical field

The invention relates to an earphone device integrated with a microphone, in particular to an earphone device which integrates the microphone and the earphone and is more convenient to use.

Background technique

The use of earphones to receive sound has become an indispensable way of life in modern life. Whether listening to music on an airplane or using a walkman, radio or mobile phone in daily life, earphones can be used. In addition, some earphones must be used together with a microphone in actual use, such as the known hands-free device used in mobile phones.

Referring to Fig. 1, the known hands-free device has an earphone 90 and a microphone 91, and the earphone 90 and the microphone 91 are independent entities. After the earphone 90 and the microphone 91 utilize the signal line 92 to connect with the mobile phone 93, The earphone 90 can be used to plug into the user's ear so that the electronic signal of the mobile phone 93 can be converted into an audible sound, and the microphone 91 can be placed roughly near the user's mouth to receive the user's speech. sound, and convert the sound into an electronic signal and send it to the mobile phone 93. Such as Taiwan patent TW542500 announced on July 11, 2003) promptly discloses a kind of technical scheme of "hands-free receiver device".

Therefore, the known earphones and microphones are independent entities. When in use, the earphones and microphones need to be installed and fixed in different positions respectively, which inevitably causes inconvenience in installation, especially if the microphone is not fixed when in use, it is easy to Vibration is generated, which is not conducive to receiving sound.

Although it is known that the microphone has been clamped on the user's clothing by using a clamp, this method of adding a clamp will cause the overall structure to be complicated, resulting in increased manufacturing costs, and the microphone exposed to the outside will also affect the appearance. It will hinder the user's activities, and often accidentally touch the microphone, causing inconvenience to the user.

Therefore, it can be seen from the above that the above-mentioned known earphones and microphones obviously have inconveniences and defects in actual use, and there are places that need to be improved.

Contents of the invention

The main purpose of the present invention is to provide an earphone device integrated with a microphone, which integrates the microphone and the earphone into one body, is more convenient to use, and can make the microphone easy to install without shaking, and can be beneficial to receive sound. Moreover, the overall structure is simplified, the manufacturing cost is low, and the microphone is not exposed to the outside.

In order to achieve the above technical purpose, the present invention provides an earphone device integrated with a microphone, comprising: a body; a microphone unit connected to the body to sense and receive the vibration generated when the user makes a sound, and The vibration signal is transmitted to an electronic device through a circuit unit; and a loudspeaker unit is arranged inside the microphone unit to convert the electronic signal of the electronic device into audible sound.

The present invention mainly integrates the microphone unit into the earphone device, so that the earphone device has both the functions of the earphone and the microphone. The earphone and the microphone form an integrated structure. When in use, they are installed and fixed at the same position together, which is more convenient for installation, and The microphone unit can be well fixed without shaking, and it is good for receiving sound. In addition, the microphone unit does not need to be clamped on the user's clothing by a clamp, the overall structure is simplified, and the manufacturing cost is low, and the microphone unit is fixed together with the earphone device, so that it will not be exposed to the outside, will not affect the appearance, and will not Interfering with the activities of the user and causing inconvenience to the user.

Detailed ways

Please refer to Fig. 2 and Fig. 3, the present invention provides a kind of earphone device integrated with microphone, comprises a body 1, a microphone unit 2 and a speaker unit 3, wherein the body 1 is a hollow shell made of plastic material Body, one end of which forms a connecting portion 11 for connecting the microphone unit 2 and the speaker unit 3 .

The microphone unit 2 includes a sound-absorbing membrane 21 and a circuit unit 22 , the sound-absorbing membrane 21 is a hollow cylinder, and can be used to plug into the user's ear canal and closely contact with the inner wall of the ear canal. The rear end of the sound-absorbing membrane 21 is fixedly joined to the connecting portion 11 of the main body 1 . The circuit unit 22 includes electronic components such as transistors and capacitors (not shown in the figure). The circuit unit 22 is arranged inside the sound-absorbing film 21 and is properly fixed to the body 1. The circuit unit 22 is also electrically connected to the sound-absorbing film 21. , 22 and is also electrically connected with a signal line 4, the other end of the signal line 4 passes through the body 1, and can be used to electrically connect with electronic devices such as mobile phones. This embodiment is a wired earphone, so the signal line 4 is provided. If it is applied to a wireless earphone or a Bluetooth earphone, the signal line 4 does not need to be provided. The sound-absorbing film 21 of the microphone unit 2 can be used to plug into the user's ear canal, and can be used to sense and receive the vibration generated when the sound is made, and transmit the signal absorption to the circuit unit 22.
