The present invention relates to the antenna coupling structure in a portable wireless mobile communication terminal having an antenna structure, which is installed inside the terminal, of the portable wireless mobile communication terminal, which becomes a planar pattern and is embedded inside the wireless mobile communication terminal. While maintaining a sufficient clearance between the antenna and the printed circuit board, at the same time to prevent the cancellation of mutual impedance between the pattern of the antenna and the speaker, it is possible to prevent the RF characteristic degradation caused by being in close proximity between the speakers, In addition, the speaker characteristics are also improved, and the antenna structure of the portable wireless mobile communication terminal for high communication quality with low output and reliability due to the distribution of load resistance is provided.

With the development of wireless communication technology, portable terminals such as cellular phones and PHS (Personal Handyphone System) devices have been widely used. With the rapid increase in the number of users, their functions are being developed in various ways. It is well known that there is a trend to be further improved to increase the usefulness and convenience of the portable terminal according to the demand of the consumer.

As is well known in the portable wireless mobile communication terminal, an antenna, which is a device that receives radio waves flowing outward and transmits a signal transmitted from another device inside, is essentially provided.

Such a portable terminal uses a pull-out linear monopole antenna, a fixed helical antenna, or the like by a so-called monopole antenna method that protrudes from the case to the outside.

However, such antennas are caused by electromagnetic waves, and in the case of the external antenna as described above, due to the problem that the portability of the antenna is less convenient due to protruding antennas and damage, the internal antennas are recently inserted into the terminals. (Built-in) There is a trend to require antennas.

As described above, an antenna built into the terminal is called an intenna. A flat antenna using a micro strip patch, such as an inverted F, which is recently disclosed, is supplied to a feed line in a pattern formed on a radiation patch in a predetermined shape. The magnetic current is generated by the high frequency power, and the magnetic current forms a leakage electric field so as to be transmitted and received.

As described above, the planar antenna using the micro strip patch may be formed in various shapes to form a compact and thin film, and thus, is widely applied as an internal antenna of a wireless terminal.

However, in the case of the installation form in the wireless terminal using the intenna having a flat pattern as described above, the conventional technology is described, the speaker is seated in a position close to the sound output port and the printed circuit board is seated inside the terminal body. And it has a structure that is connected to the printed circuit board, the antenna is located above the speaker and is accommodated in the terminal body, it can provide a structure that is fixedly coupled by the rear cover.

Such a structure is generally a structure of a wireless terminal including an intenna which can be commercialized, and an intenaphone having a different structure, for example, an intenaphone fixed in a state in which the position of the intena is separated from the speaker, except in the scope of the present invention. Can be.

On the other hand, in a state in which the speaker and the antenna are in contact with and coupled to the main body of the terminal, when the communication is performed, the signal received from the antenna is converted into an audio signal on the printed circuit board and amplified and output to the user through the speaker. However, there is a problem in that the RF characteristic, which is a high frequency characteristic, is degraded on the position where the voice coil and the antenna of the speaker are close to each other.

Therefore, in order to obtain the desired RF characteristics, it is recommended to space the minimum separation distance of 7mm or more based on the ground of the printed circuit board and the antenna, but the terminal body is getting thinner and thinner. Due to the narrow space, it is not easy to sufficiently secure the above-mentioned recommended separation distance, and as a result, the separation reference distance is narrowed to the speaker and the antenna by the connection between the printed circuit board and the speaker within the secured separation distance. Since the reinforcing effect of the impedance is not guaranteed, the problem of deteriorating RF performance in use is inevitable.

This problem also has the same problem in the case of Korean Patent Application Publication No. 10-2005-33764 previously filed with the Korean Intellectual Property Office.

That is, in the case of the above-mentioned Patent Publication, rather than contemplating overcoming such a problem, an antenna and a speaker are integrated in order to cope with slippage of the terminal. The problem of not being able to express maximally is inevitable.

Accordingly, the present invention has been made to solve the above problems, and is improved to minimize the interference between the speaker and the antenna pattern existing in the narrow space of the wireless terminal by the antenna to improve the RF performance, which is a high frequency characteristic. The purpose is to provide a coupling structure of the speaker.

In addition, the present invention has another object to improve the speaker characteristics by configuring two speakers in a set under the same narrow volume conditions.

The present invention for achieving the above object,

In the fixed coupling structure between the antenna and the speaker in the intenaphone,

Yoke 220, voice coil 230 and the diaphragm 240, etc. are accommodated in the case 210 and the terminal body 200 and the antenna 300 for the terminal is finished by the cap 250, the terminal body of the intenaphone In the structure fixedly coupled in (100),

The coupling hole 211 is formed at the periphery of the case 210, and the coupling hole 211 is opened downward through the rear part to be opened to form an acoustic induction hole 262 for guiding sound in a "┏" direction. The speaker 200 is fixedly received into the acoustic induction case 260 integrally protruding along the rear periphery of the rear side of the coupling protrusion 261 to be inserted into the opening 211, and thus the sound output port of the terminal body 100 ( 130, the speaker 200 is vertically fixed in the state in which the sound induction hole 262 is in contact with the side.

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

The present invention, as shown in the accompanying drawings, by minimizing the interference between the antenna 300 and the speaker 200 in the antenna, it is possible to output a state in which the sound output due to the cancellation of the impedance is not degraded high quality RF In order to have the characteristics and to improve the speaker characteristics, the coupling structure of the speaker 200 was improved, and the speaker 200 was fixed so as to be vertically entered with the ground pattern which becomes the plane of the antenna 300, but the vertical The sound output from the speaker 200, which is fixed in the standing position, is diffracted to the sound output port 130 of the terminal body 100 and provides a structure to be output immediately.

1 is an exemplary view to which the present invention is applied, and as shown in the drawing, the speaker 200 for a wireless terminal generally employed is accommodated in the acoustic induction case 260 provided by the present invention, and then vertically. It was supposed to fix the standing.

The speaker 200 generally has a structure that is commercially available, and includes a yoke 220 including a magnet (not shown), a voice coil 230 seated on the yoke 220, and a position above the voice coil 230. After the diaphragm 240 is coupled to each other and accommodated in the case 210, the diaphragm 240 is formed by a cap 250 covering the case 210.

On the other hand, the coupling hole 210 is formed in the peripheral portion of the case 210.

The speaker 200 is configured to deviate from a conventional coupling structure. The speaker 200 accommodates the speaker 200 so that the speaker 200 is installed in a vertical direction, instead of being fixed in a plane that corresponds to the direction of the ground pattern of the antenna 300. By providing a sound induction case 260 to vertically stand, the speaker 200 is accommodated in the sound induction case 260 is configured to be fixed in the standing.

In addition, by making the speaker 200 relatively small and configured in a set, by connecting the two small speakers 200 in parallel or in series, it is possible to improve the acoustic characteristics of the speaker 200, the load accordingly The resistance was reduced so that the reliability could be doubled.

The acoustic induction case 260 is made in a rectangular shape as shown in the drawing, but when viewed from the drawing, the rear part is opened and is associated with one side, that is, the front side lower part and has an open shape, through the rear part being opened. The speaker 200 is accommodated.

That is, as shown in the drawing, a structure in which one side (back side in the drawing) opened in the acoustic induction case 260 which becomes a rectangular shape and the other side (front side lower part in view as shown in the figure) which is perpendicularly perpendicular to each other is opened. In this state, when combined with the terminal main body 100, the shape of the cross section is viewed as a "┏" shape when viewed in cross section. The speaker 200 is vertically received and fixed to the inside thereof.

Therefore, in order to maintain the state in which the speaker 200 is accommodated in the acoustic induction case 260, the coupling hole 211 is formed at the periphery of the case 210 for accommodating the elements of the speaker 200, and the coupling hole ( In order to be coupled to 211, the coupling protrusions 261 are formed to protrude integrally with the peripheral portion of the rear side of the acoustic induction case 260 in contact with the peripheral edge side of the case 210, respectively.

By the coupling protrusion 261, the entire speaker 200 can be fixed in a state accommodated in the acoustic induction case 260, and the antenna 300 having a flat pattern has an acoustic induction case 260. Covering the upper surface of the one side of the printed circuit board 120 and the ground terminal 310 of the antenna 300 is fixed in a grounded state.

When communicating via a portable wireless mobile communication terminal using the present invention by the above configuration, when receiving a radio wave transmitted from the outside through the antenna 300, the ground terminal 310 of the antenna 300 After input to the printed circuit board 120 through the amplified, the sound is output through the speaker 200.

At this time, the sound output from the speaker 200 is diffracted through the sound induction hole 262 in the direction orthogonal to be output to the sound output port 130 that is perforated by the terminal body 100.

5 is a diagram showing the results of testing the RF performance using the terminal to which the present invention is applied, FIG. 5a is a result of the RF performance test before the present invention is applied, and FIG. 5b is an RF performance test of the present invention to which the present invention is applied. The result is.

As shown in the graph, the test results of two types of GSM BAND and DCS BAND showed that each BER and POWER value had a superior effect on the performance after application than the data value before the application of the present invention.

In addition, Figure 6 is a result of testing the speaker characteristics to which the present invention is applied, Figure 6a is a result of testing the general speaker characteristics not applied to the present invention, Figure 6b is a result of testing the characteristics of the speaker to which the present invention is applied As shown in the graph, it can be seen that the characteristics of the speaker in the state of the present invention are significantly improved as shown in each graph.

Therefore, as shown in the drawing, since the speaker 200 and the antenna 300 are in a form orthogonal to each other, the impedance input through the printed circuit board 120 and the antenna 300 being energized, and the printed circuit board ( The amplified voice signal from 120 minimizes the mutual cancellation effect between the output impedances generated through the speaker 200, thereby improving RF characteristics, and also having an excellent output performance of the speaker.

Therefore, according to the present invention, it is possible to prevent the RF characteristic deterioration caused by being in a position close to the intenna and the speaker which are built into the wireless communication terminal in a planar pattern as in the related art, and also improves the speaker characteristic. In addition to the effect is expected to be reliable due to the distribution of the load resistance, it is possible to always express high quality RF characteristics, thereby improving the call quality when using a portable wireless mobile communication terminal.
