Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a circuit diagram according to an embodiment of the device according to the present invention, which has three signal lines (L1-L3) and a jack (J) including left and right speakers (L SP, R SP) and a common signal line. In the earphone,

An acoustic signal detector (1) connected in series with the common signal line (L3) of the earphone to detect an electrical acoustic signal output to the left and right speakers (L SP, R SP);

A switching unit (2) installed between the sound signal detector (1), the battery (BAT), and the light emitting member (4) for switching in response to the magnitude and frequency of the sound signal output from the sound signal detector (1); ;

A battery BAT for supplying a power voltage to each part;

A power switch SW for controlling the supply of the power voltage;

The light emitting member 4 which is connected to the output terminal of the switching unit 2 in a state where it is attached to a part of an outer side of the signal line of the earphone and emits light having a brightness and a flashing period corresponding to the output signal size and frequency of the switching unit 2. It consists of the basic features.

In this case, the light emitting member 4 may be driven by a direct current voltage, and the light emitting member 4 is connected to several light emitting diodes (LED 1 -LED n) in series to be placed in a transparent shrinkage tube 41 free of warpage, and the switching unit 2 ) Is composed of a switching transistor (Q), a reverse voltage prevention diode (D), load resistors (R1, R2) and an electrolytic capacitor (C).

FIG. 2 also shows a circuit diagram according to another embodiment of the present invention, whereby the predetermined frequency output from the switching unit 2 between the output terminal of the switching unit 2 and the light emitting member 4 is low. An inverter 3 for converting a DC voltage into a high AC voltage is provided.

In this case, when the inverter 3 is additionally installed, the light emitting member 4 itself must be driven by an AC voltage. Therefore, in the present invention, the light emitting plate body 43 is located outside the wire 42 embedded in the transparent shrinkage tube 41. ) And a light emitting fiber 40 that emits light in various color colors.

In addition, in the present invention, the number of turns of the primary coil is very small and the number of turns of the secondary coil is very large. In the present invention, the acoustic signal detection unit 1 also employs a large number of transformers (T). If it is not provided, you may select which element (for example, resistance with very low resistance value).

On the other hand, all parts constituting the apparatus of the present invention except for the light emitting member 4, that is, the acoustic signal detection unit 1, the switching unit 2, the battery (BAT), the power switch (SW) and the inverter (3) ) Is embedded in the mold 5 installed at the signal line branch of the earphone, but the power switch SW is exposed to the outside, and a lid for replacing the battery BAT is installed at the rear of the mold 5.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, an acoustic signal detection unit configured as a transformer T to a common signal line L3 of three signal lines L1 to L3 for transmitting an output signal of an acoustic device to the left and right speakers L SP and R SP of the earphone ( By installing 1), the stereo sound signal output from the sound device can be detected smoothly by the sound signal detection unit 1 as an electric signal.

At this time, the acoustic signal detection unit 1 is constituted by a transformer T to electrically insulate the acoustic signal from the device of the present invention, and the primary coil of the transformer T is wound a small number of times. The resistance value is very small so that it does not affect the output signal of the acoustic device to the left and right speakers (L SP, R SP).

Meanwhile, when the earphone jack provided with the device of the present invention is connected to an acoustic device and the power switch SW is operated, the sound detected by the acoustic signal detection unit 1 in a state connected in series on the common signal line L3 of the earphone The signal is input to the switching unit Q, which is composed of a switching transistor Q, a reverse voltage preventing diode D, and load resistors R1 and R2 and a capacitor C. The switching and amplifying operation is performed in response to the magnitude and frequency of the sound signal output from the sound signal detection unit 1.

In this case, when the light emitting member 4 is directly connected to the output terminal of the switching unit 2 as shown in FIG. 1, the light emitting member 4 is connected to the magnitude and intermittent frequency of the DC voltage output from the switching unit 2. It emits light with a corresponding brightness and flashing cycle. In this case, since the voltage output from the switching unit 2 is a DC voltage, several light emitting diodes (LED1-LEDn) can also operate to the DC voltage. It is good to install what was put in the transparent shrinkage tube 41 which bends freely in series.

However, when the light emitting member 4 is formed using several light emitting diodes (LED 1 -LED n) and the transparent shrinkage tube 41 as described above, the circuit itself is simplified, but the manufacturing cost of the light emitting member 4 is increased. Of course, when installed on a part of the signal line of the earphone there is a fear that the signal line does not bend freely.

Therefore, the light emitting member 40 emits light of various colors by having a configuration in which the light emitting plate body 43 is provided in the form of a coil to the outside of the wire 42 embedded in the transparent shrinkage tube 41. In this case, since it is operated by an AC voltage, an inverter 3 is installed between the output terminal of the switching unit 2 and the light emitting member 4 as shown in FIG. At a predetermined frequency at a low output DC voltage is converted into a high AC voltage to be applied to the light emitting fiber (40).

Therefore, the light emitting fiber 40 installed as the light emitting member 4 can be turned on and off by the AC voltage output from the inverter 3 in response to the magnitude and frequency of the acoustic signal.

Of course, the two elements presented as the light emitting member 4 is illustrated in the signal line between the normal part of the signal line of the earphone (in the present invention, the mold 5 and the left and right speakers (L SP, R SP)). However, the present invention is not limited thereto, and is attached to the entire signal line or the mold line 5 and the jack (J). Since the light emitting member 4 emits light in response to an acoustic signal between devices, the peripheral parts can be more beautifully created.

In the above, the acoustic signal detection unit 1, the switching unit 2, the battery BAT, the power switch SW, and the inverter 3 are incorporated in the mold 5 provided at the signal line branch point of the earphone. In addition, the earphone itself does not impair the quality of the earphone or the use of the earphone, and the power switch (SW) is exposed to the outside of the mold (5), so even if you operate the light emitting member (4) can expect the effect If the light emitting member 4 should not be operated even during daytime or even nighttime, the user can easily shut off the operation and also prevent unnecessary consumption of the battery BAT. Although not shown in the rear portion of the water (5), because the lid is installed, it is possible to easily replace the battery (BAT).

On the other hand, in the drawing is shown an earphone that can listen to the stereo output signal of R, L, but is not limited to this mono earphone or headphone that can only listen to one output signal (for example, connected to a mobile phone or a computer, etc.) It can also be applied to headphones, etc.).

As described above, according to the present invention, by installing a light emitting member that emits light in response to the magnitude and frequency of the sound signal output from the sound equipment on the outer part of the signal line of the earphone, the ambient atmosphere when listening to the sound signal Not only can it be created beautifully, it can also greatly improve the merchandise and reliability of the earphone itself.
