The present invention relates to a mobile communication terminal having an integrated structure of a microphone and a kit, and more particularly, a gap between the case and the case surface by allowing the microphone of the terminal to be directly fixed to the I / O connection terminal face of the kit in the main body case. And greatly simplify the work process.

In general, a folder type of which a mobile communication terminal is a representative type will be described as an example. As a main component, a folder part having a screen part and a keypad for rotatably coupled with the folder part to perform various functional operations are provided. The main body and a battery for supplying power are provided.

These terminals are provided with a microphone and a receiver for transmitting and receiving with the other party, and the PCB is provided inside the main body.

With reference to the accompanying drawings illustrating in more detail as follows.

As shown in FIG. 1, the PCB body 20 is installed inside the terminal body case 10, and the microphone 30 is installed and fixed on the PCB 20. ), When the microphone 30 itself has a predetermined height, the gap D with the main body case 10 must be maintained, so that the microphone 30 cannot be directly fixed to the PCB 20 and the surface of the PCB 20 is After cutting to a predetermined size to form a large hole 21, and bent the FPCB (40) in a recessed form, both ends were fixed by soldering, and then the microphone 30 was fixed on the FPCB (40).

Therefore, the FPCB 40 is separately provided and fixed to both ends of the hole 21 of the PCB 20 in a bent form, and then the microphone 30 is installed to secure the gap D between the main body case 10. Could.

However, because a large hole 21 is drilled on the PCB 20 as described above, the FPCB 40 is soldered and fixed, and the microphone 30 is installed to form a gap D. This is complicated, there is a problem that the work time is delayed, and the product cost increases.

If the microphone 30 is directly installed on the surface of the PCB 20 without forming the hole 21 on the surface of the PCB 20, a gap D between the microphone 30 and the terminal body case 10 of the terminal 20 is provided. ) Will be narrowed or almost eliminated. Then, there is a problem that may cause damage to the microphone 30 or a short phenomenon due to an external impact.

Therefore, in order to maintain the gap D, since the terminal itself is enlarged to secure the gap D, there are many limitations in achieving miniaturization of the product.

Accordingly, the present invention has been invented to solve the conventional problems as described above, by eliminating the space constraints by directly installing the microphone on the surface of the kit under the PCB, which is essentially provided in the terminal, the terminal body portion SUMMARY OF THE INVENTION An object of the present invention is to provide a mobile communication terminal having a microphone and a kit integrated structure that can reduce the product cost by simplifying a work process while maintaining a gap with a case.

The present invention for achieving the above object is to penetrate the PCB provided inside the terminal case so that the microphone is integrally fixed to the surface of the kit to maintain the gap with the case to reduce the thickness of the terminal This is a technical feature.

The car kit is made of a synthetic resin material to enable injection molding integrally with the microphone.

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

The same components as in the prior art will be described with the same reference numerals, and detailed description thereof will be omitted, and new components will be described in detail with the new reference numerals.

As shown in the accompanying drawings of FIG. 2, the present invention is basically equipped with a PCB 20 inside the terminal body case 10 as in the prior art.

In addition, an I / O connector 51 is formed inside the carkit 50, and an I / O connection capable of coupling an I / O connector (not shown) in the I / O connector 51. The terminal 52 is provided.

Here, the present invention has a structure in which the microphone 30 is integrally molded with the kit 50 and installed like a set.

That is, the I / O connector 51 is injection molded with the microphone 30 as a synthetic resin material. After injection molding, various signal wires to and from the microphone 30 are connected. For example, a pin-shaped wire part 53 is provided on the drawing.

In the figure, reference numeral 53 is a wiring pin.

According to the present invention having such a configuration, the microphone 20 is inserted into the PCB 20 inside the main body case 10 by inserting the microphone 30 by inserting the microphone 30, and then the PCB 20. It is to be fixed directly to the surface of the I / O connector 51 constituting the kit (50) provided on the bottom of the), the work process is simple, thereby reducing the working time significantly.

Moreover, through this simple operation, the gap D between the microphone 30 having the predetermined height and the main body case 10 can be naturally secured.

As described above, the present invention is provided by integrally forming the microphone and the kit provided in the terminal, thereby reducing the number of manufacturing steps of the product and further securing a gap with the terminal case, thereby reducing the thickness of the product and achieving miniaturization. It works.

Although the present invention has been described for convenience of the present invention with reference to the accompanying drawings, it is obvious that various modifications and changes are possible within the scope of the technical idea of the present invention.
