1. Field of the Invention
The present invention is related to an earphone device integrated with a microphone, and more particularly to an earphone device in which a microphone and an earphone are integrated together for facilitating use thereof.
2. Description of Related Art
Use of an earphone to receive sound input is common. Activities such as listening to music on an airplane, or using a Walkman, radio or mobile phone are conducted with the use of earphones. Moreover, some earphones are combined with a microphone, in applications such as the hands-free device for a mobile phone.

However, the conventional earphone and microphone are independent of each other, and thus must be placed in different positions during use. This is unavoidably inconvenient for assembly. In particular, when using the microphone, if the microphone is not fixed, it is easily shaken, which is unfavorable for voice reception.
Although the conventional microphone has developed to be clipped on the clothing of the user with a clip, this clipping manner causes a complex structure and also an increased cost. Further, the exposed microphone also influences the user's appearance, and hinders the activity of the user due to accidental contact. Therefore, it is quite inconvenient.
The main object of the present invention is to provide an earphone device integrated with a microphone, in which the microphone and the earphone are integrated together for facilitating use thereof, to provide convenient microphone assembly without shaking, to receive a user's voice, to simplify the whole structure thereof, and to reduce the cost thereof. Further, the microphone is not exposed.
For achieving the above objects, the present invention provides an earphone device integrated with a microphone including a main body, a microphone unit connected to the main body, and a speaker unit mounted inside the microphone.
According to the present invention, the microphone unit is integrated in the earphone device such that the earphone device may concurrently have the functions of earphone and microphone. While in use, the earphone and the microphone are fixedly assembled in the same position, together, so that the assembly is more convenient and the microphone is more stable, which facilitates sound reception. Furthermore, the microphone does not need a clip to clip onto the clothing worn by the user, so the whole structure can be simplified and the manufacturing cost can be reduced. Moreover, the microphone is plugged into the ear canal of the user together with the earphone device, so it is not exposed, and thus, the user's appearance will not be influenced and the activity of the user will not be hindered, either.
The foregoing aspects and many of the attendant advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

The microphone unit 2 includes a sound-absorbing film 21 and a circuit unit 22. The sound absorbing-film 21 is a hollow column capable of being plugged into the user's ear canal, in tight contact with the inner wall thereof, and the rear end of the sound-absorbing film 21 is fixedly linked to the connecting portion 11 of the main body 1. The circuit unit 22 includes electronic elements such as transistors and capacitors (not shown). The circuit unit 22 is positioned inside the sound-absorbing film 21, properly fixed on the main body 1, and electrically connected to the sound-absorbing film 21 and also to a signal line 4. Another end of a signal line 4 penetrates through the main body 1 for being electrically connected to an electronic device such as a mobile phone. It is noted that in this embodiment, a wired earphone is illustrated, so the signal line 4 is included. If applied in a wireless earphone or Bluetooth earphone, then the signal line 4 is not needed. The sound-absorbing film 21 of the microphone unit 2 can be plugged into the ear canal of the user, is capable of sensing or receiving the vibration generated, and can absorb the signal and then transmit it the same to the circuit unit 22. The sound-absorbing film 21 adopts a contact sensing manner for sound absorption, blocking interference from the sound from the speaker unit 3. Furthermore, the front end of the sound-absorbing film 21 also can be connected to a cover 5, which has plural sound-holes 51 therein for outputting the sound of the speaker unit 3.
The speaker unit 3 is mounted inside the sound-absorbing film 21 of the microphone unit 2 and is properly fixed on the main body 1. The speaker unit 3 is a miniature speaker including a housing 31, a permanent magnet 32, a coil 33 and a vibrating film 34, as shown in
According to the present invention, the microphone unit 2 is integrated in the earphone device; namely, the microphone 2 is mounted on the peripheral of the speaker unit 3 of the earphone device, such that the earphone device may concurrently have an earphone and a microphone function. During use, the whole structure formed by the earphone and the microphone is fixedly assembled in the same position, for example, plugged in the ear canal of the user, so the assembly thereof is more convenient and the microphone is more stable, which facilitates sound reception.
Furthermore, the microphone 2 of the present invention does not need a clip to clip on the clothing worn by the user, so the whole structure can be simplified and the manufacturing cost can be reduced. Moreover, the microphone 2 is plugged in the ear canal of the user together with the earphone device, so it is not exposed. The appearance of the user is thus not influenced, and the activity of the user is not hindered, either.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
