6 is a cross-sectional view of FIG.

First, Figure 3 is a perspective view of the whole view of the present invention, the present invention comprises a lid 110 and the handle 120 which is the entrance to the voice is largely input.

The lid 110 is open at one side and generally has an oval or spherical shape.

In addition, the handle 120 is about a comfortable grip when holding the housing in a normal adult hand and the on-off switch 123 is located in the middle, and the lid 110 is threaded on the upper side of the handle 120 ( 121 is coupled to form a spherical lid 110 is coupled to the stick-shaped handle 120 as a result.

In addition, the handle 120 is screwed to the screw thread 10 of the battery case 10 constituting the inner case 100 and the screw thread 122 formed on the inner circumference of the handle 120 is screwed and fixed.

In addition, the handle 120 and the lid 110 forms an outer case of the microphone, and the inside of the outer case converts a voice signal into an electrical signal and relays it to the amplifier through a connector located at the bottom of the handle. The device is inserted.

The relay device is built in the inner case 100 inside the microphone, and is connected by a wire (not shown) between the microphone and the amplifier.

In addition, the inner case 100 includes a voice change device, a power supply device, and devices for filtering according to a required frequency.

This will be described in more detail as follows.

The inner case 100 of the present invention further includes a sound absorber case 20, a battery case 10, and a connection connector 30 connecting the sound absorber case 20 and the battery case 10.

The flaw device case 20 has a vertical axis opening, a tapered cylindrical shape as a whole, and a sound absorbing device 40 is built in the inside thereof.

The battery case 10 also has an open shape on a vertical axis, and includes a battery 60 for supplying a DC voltage and a substrate 50 for filtering only a frequency band required for a signal for converting a voice into an electrical signal. .

In addition, the sound absorbing device case 20 and the battery case 10 are screwed by the connecting connector 30, the thread 33 formed on the outer periphery of the connecting connector 30 is the battery case 10 Threaded thread 12 formed on the inner circumference is connected to the screw thread, and threaded thread 32 formed on the inner circumference of the connector 30 is connected to the threaded thread 21 formed on the outer circumference of the sound absorbing device case 20 by screwing. do.

In addition, a locking jaw 31 is formed at an inner circumferential center of the connection connector 30, and the locking jaw 31 prevents the battery 60 from protruding to the outside and impacts other devices.

That is, if the hooking jaw 31 is not formed in the connection connector 30 in the above, since the battery 60 embedded in the battery case 10 may shock the sound absorbing device 40 to cause the fixing. to be.

As a result, the inner case 100 may be divided into three parts, the sound absorbing device case 20, the connector 30 and the battery case 10, and the sound absorbing device case 10 includes a sound absorbing device ( 40 is built in the battery case 10, the battery 60 and the voice signal conversion unit 50 is built. For reference, the sound absorbing device is shown in detail in FIG. 4.

The sound absorbing device 40 includes a vibrator 41 for converting air vibrations due to speech into an electrical signal, a rectifying substrate 42 for reducing the distortion of the output signal of the vibrator 41, and the vibrator 41. ) And an elastic spring 43 that elastically supports the substrate 42. Reference numeral 46 is a pattern for smoothing the electrical signal of the vibrator, 47 is a wire connecting the pattern and the vibrator.

The reason why the elastic spring 43 is used as the support means is to support the shotgun when a physical shock is applied to the sound absorbing device 40 from the outside.

If the vibrator and the substrate are attached by soldering without using the elastic spring 43 as described above, there is a high possibility that the vibrator breaks during an external physical shock. There was a case where the whole had to be changed.

However, when the elastic spring 43 is used as in the present invention, it is possible to properly compensate for the impact applied from the outside to prevent the vibrator 41 from being easily broken, even if the vibrator 41 is broken, the sound absorbing device. Since only the sound absorbing device 40 needs to be disassembled by disassembling the case 20, the microphone can be fixed quickly without incurring a large cost.

In addition, the outer edge portion of the rectifying substrate 42 has a ground line 44 is formed, the ground line 44 is a combination of the suction device case 20 and the connection connector 30, respectively The housing is in close contact with the ground to ensure good electrical signals.

In addition, a predetermined number of ground lines 45 are further formed on the outer periphery of the rectifying substrate 42 so that the outer periphery of the substrate 42 and the connection connector 30 closely contact each other so that the ground of the signal rectified by the substrate is smooth. It was done to help.

That is, in the related art, since the ground line does not have a pattern shape but uses a wire soldering method, the ground line may be broken by an external impact. However, in the present invention, the ground line may be patterned on the outer side of the substrate. In addition, since a certain number of ground line patterns are formed on the outer circumference thereof, it is strong against external shock and at the same time, it is possible to reliably transmit the electrical signal generated by the vibrator through the inner case 100 housing.

On the other hand, the battery case 10 is provided with a voice signal conversion unit 50 for filtering only the battery 60 and the electrical signal transmitted through the battery case 10 to output the required frequency range, the voice signal The conversion unit 50 serves to output only a predetermined frequency range in the electrical signal transmitted through the inner case 100 so that the speech sound is transmitted without distortion.

That is, there are various types such as those used to amplify music according to the characteristics of a microphone, those used to amplify a voice, or those used to amplify a natural sound, and used for karaoke as in the present invention. Since the microphone focuses on amplifying a person's voice, the voice signal converter passes only the appropriate frequency range to the amplifier to maximize the amplification of the voice.

In the present invention, the engaging jaw 13 is formed in the battery case 10 so that the substrate constituting the audio signal converting unit 50 can be freely rotated, and the audio signal converting unit 50 is the engaging step 13. Is inserted into the battery case 10 to be rotated freely without exiting to the outside.

As described above, when the substrate constituting the voice signal converter 50 is freely rotated, the wire 124 connected to the connector 51 connected to the substrate is not twisted, thereby avoiding wire disconnection, thereby reducing the defect factor. .

That is, in the related art, since the voice signal converter is connected by soldering, when the inner case and the knob to which the voice signal converter is connected are locked, the wires connecting the output port of the microphone and the output port of the microphone may be twisted and broken. However, when the present invention is used, since the substrate constituting the voice signal conversion unit rotates freely, when the inner case and the handle are screwed together, the substrate constituting the voice signal conversion unit is fixed in place to prevent the wire from being broken. Will be.

After all, the present invention is to subdivide the inner case to be connected by screwing all together to replace only the failed couple to increase the economics, to reduce the risk of failure by adding a spring for absorbing shock to the sound absorbing device, the projection jaw to the battery case It is formed to allow the substrate of the voice signal converter to rotate freely, thereby preventing the internal wires of the microphone from being broken, thereby providing an effect of using the microphone for a long time.

Although the present invention has been described in connection with the above-mentioned preferred description, various other modifications and variations may be made without departing from the spirit and scope of the invention. Accordingly, the appended claims may be determined to include such modifications and variations as fall within the true scope of the invention.
