Earphone device integrated with microphone

An earphone device integrated with a microphone has a main body, a microphone unit and a speaker unit. The microphone unit has a sound-absorbing film and a circuit unit, the sound-absorbing film being a hollow column and being connected to the main body through a rear end thereof, and the circuit unit being fixed on the main body and electrically connected to the sound-absorbing film. The speaker unit is mounted inside the sound-absorbing film of the microphone unit such that the microphone unit is located peripheral to the speaker unit. A microphone and an earphone can thus be integrated together as a whole so as to form an earphone device that can be used conveniently.

BACKGROUND OF THE INVENTION

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.

Reference is made toFIG. 1. A conventional hands-free device includes an earphone90and a microphone91, which are independent of each other. In the device, after the earphone90and the microphone91are connected to the mobile phone93through a signal line91, the electronic signals from the mobile phone93can be converted into sound, which can be heard by human ears. The user can hear the sound by plugging the earphone into the ear. Additionally, the microphone91is approximately positioned around the mouth of the user to pick up the voice of the user; the voice can then be converted into electronic signals and transmitted to the mobile phone93.

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.

SUMMARY OF THE INVENTION

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.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

References are made toFIGS. 2 and 3. The present invention provides an earphone integrated with a microphone including a main body1, a microphone unit2, and a speaker unit3. The main body1is a hollow housing made of plastic material, one end of which is formed as a connecting portion11for connecting the microphone2with the speaker unit3.

The microphone unit2includes a sound-absorbing film21and a circuit unit22. The sound absorbing-film21is 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 film21is fixedly linked to the connecting portion11of the main body1. The circuit unit22includes electronic elements such as transistors and capacitors (not shown). The circuit unit22is positioned inside the sound-absorbing film21, properly fixed on the main body1, and electrically connected to the sound-absorbing film21and also to a signal line4. Another end of a signal line4penetrates through the main body1for 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 line4is included. If applied in a wireless earphone or Bluetooth earphone, then the signal line4is not needed. The sound-absorbing film21of the microphone unit2can 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 unit22. The sound-absorbing film21adopts a contact sensing manner for sound absorption, blocking interference from the sound from the speaker unit3. Furthermore, the front end of the sound-absorbing film21also can be connected to a cover5, which has plural sound-holes51therein for outputting the sound of the speaker unit3.

The speaker unit3is mounted inside the sound-absorbing film21of the microphone unit2and is properly fixed on the main body1. The speaker unit3is a miniature speaker including a housing31, a permanent magnet32, a coil33and a vibrating film34, as shown inFIG. 4. The housing is a hollow housing made of a metal material and one end thereof has a sound-outputting hole311, which faces the sound-holes51of the cover5. The permanent magnet32, the coil33and the vibrating film34are mounted inside the housing31, the coil33is electrically connected to the vibrating film34, and the coil33of the speaker unit3is also properly and electrically connected to the signal line4. The coil33can promote the vibrating film34to sound through being driven by the signal current for converting the electronic signal of an electronic device, such as a mobile phone, into a sound that can be heard by a human ear. The vibrational direction of the vibrating film34is perpendicular to the sound-outputting hole311of the housing31, such that the sound wave sent out by the vibrating film34can be reflected by the housing31and then sent out by the sound-outputting hole311. This prevents the sound wave from being directly transmitted to the ear of the user and causing discomfort for the ear drum. Moreover, a sound-absorbing material6is mounted between the speaker unit3and the sound-absorbing film21of the microphone unit2. The sound-absorbing material6is silica gel, by which a sound isolation area can be formed so that the speaker unit3does not interfere with the sound-absorbing film21. Through the composition described above, the earphone device integrated with microphone can be achieved.

According to the present invention, the microphone unit2is integrated in the earphone device; namely, the microphone2is mounted on the peripheral of the speaker unit3of 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 microphone2of 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 microphone2is 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.
