The present invention relates to a separate sound input / output device, and more particularly, to effectively block the effects of noise generated in the surrounding environment, as well as to separate the sound input unit and the output unit to solve the problem such as howling phenomenon. And a detachable acoustic input / output device.

In general, many devices that can input and output sound while being less affected by the noise generated in the surrounding environment have been developed.

These devices are classified into earphones inserted into the ear and microphones located near the oral cavity, and are widely applied to portable audio players and portable mobile terminals.

However, in this type of input / output device, not only the signal generated from the outside can be input through the microphone in an exposed state, but also the distance between the microphone and the oral part of the human body can be changed while moving, so that the level of the signal can be changed. Can be.

In order to improve the above problems, Korean Patent Application No. 2001-0061260 discloses a product of an earphone and a microphone.

For example, the present invention discloses a type including a microphone, a speaker, a controller, and the like in a main body that can be inserted into an ear, and the controller receives a signal output from a speaker and a signal input to the microphone, and among the signals input to the microphone. The volume of the sound signal output from the speaker is controlled so that the component of the signal output from the speaker is removed.

However, in the case of the integrated sound input / output device as described above, there is an advantage that the microphone is inserted into the ear and thus is not affected by the ambient noise. There are drawbacks to this.

Accordingly, the present invention has been made in view of the above problems, and can not only prevent noise generated in the surrounding environment from being input through the microphone, but also prevents howling and echo. The purpose is to provide an output device.

In order to achieve the above object, the present invention provides a sound input / output device comprising two main bodies each having a signal line for communication with an external device and being inserted into the ear, and generated from the ear in one main body. A microphone for receiving a signal to be input and a circuit portion connected thereto are provided, and in the other main body, a speaker for outputting an acoustic signal toward the eardrum and a circuit portion connected thereto are provided. Through the sound is characterized in that each can be input and output.

Hereinafter, a separate sound input / output device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a separate sound input device according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing a separate sound output device according to an embodiment of the present invention.

As shown in Fig. 1 and 2, the sound input / output device is basically a form that can be inserted into the ear can be used to distinguish between the listening side and the speaking side, respectively, it is possible to perform the audio transmission and reception more conveniently It consists of the way.

To this end, two main bodies 10a and 10b, which can be inserted into both ears, are provided, and each of the main bodies 10a and 10b can perform corresponding functions of sound input and output. The microphone 11 and the speaker 13 which are provided are respectively installed.

The main body (10a), (10b) is a size that can be inserted into the ear in a variety of known forms, the signal line from the outside for electrical connection with the speaker 13 side and the microphone 11 side inside 15a and 15b are connected and provided.

The microphone 11 is installed in a structure that is supported by the bracket 14 inside the main body 10a to receive a signal generated from the ear, and the circuit portion 12a having a printed circuit board shape embedded therein. It is electrically connected.

At this time, the circuit portion 12a constitutes an electrical connection relationship with an external signal line.

The speaker 13 is a known one having a diaphragm is applied, it is possible to output a sound signal toward the ear drum of the ear while being installed in the form that is usually inserted into the body (10b).

In this case, the speaker may further include an amplifier to amplify the signal input to the speaker and output it to the speaker.

Of course, at this time, one side of the speaker 13 is provided with a circuit portion 12b for the function of transmitting a sound signal input from an external device to the speaker side.

Here, the circuit portion includes a means for detecting a normal speaker signal and a microphone signal, a means for generating a control signal, a means for processing a signal, etc., a method for outputting an acoustic signal through a speaker under the control of the circuit portion and the microphone The method of inputting an acoustic signal through the method may be adopted without particular limitation as long as it is a method commonly known in the art.

Therefore, the sound signal input from the external device is output through the circuit unit 12b and the speaker 13 so that the sound can be heard through one ear, and the voice unit by the user through the other ear of the circuit unit ( 12a) and the microphone 11 can be output.

That is, the sound produced by the user is accurately output through one ear by the microphone, and the sound output by the speaker is input through the other ear. Thus, a howling phenomenon or echo caused by the proximity of the speaker and the microphone is installed as before. The phenomenon can be eliminated.

Figure 3 is a front view showing an example of the use state of the separate sound input / output device according to an embodiment of the present invention, Figure 4 is a use state of the separate sound input / output device according to an embodiment of the present invention It is a front view which shows another example.

As shown in FIG. 3, the separate acoustic input / output device of the present invention can be used in a state in which each input device and output device are separately worn on both ears, and thus, accurate and convenient without inconvenience due to howling. Can be used.

In addition, as shown in Fig. 4, in a situation where the influence of ambient noise is not so great, it can be used even when the input device, that is, the main body in which the microphone is built, is attached to the signal line by a clip or the like.

As described above, the present invention implements a new type of sound input / output system that can be inserted into the ear while being divided into earphones and microphones, thereby eliminating the howling phenomenon that has been a problem in the existing integrated input / output device. On the other hand, there is an advantage that can effectively transmit and receive sound without being affected by the noise generated in the surrounding environment.
