Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner region of the mobile terminal 100 covered by the touch screen described above or near the touch screen.

More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

[Standard end]

The antenna according to the present invention includes an antenna pattern 110 ′ formed in one region of the mobile terminal main body 100. The antenna pattern 110 ′ has a specific length to transmit and receive a radio signal in a specific frequency range. For example, the antenna pattern 110 ′ according to an example may be formed at a lower end of the mobile terminal main body 100. However, the position where the antenna pattern 110 'is formed is not limited thereto. For example, the antenna pattern 110 ′ may be formed on one region of the rear cover 103 or an inner frame constituting an internal structure of the terminal body 100.

The connector module 300 (see FIG. 2A) into which the injector is inserted is disposed adjacent to the insertion hole 161. When the length of the signal line formed on the connector module 300 and the circuit board 311 is formed to be similar to the length of the antenna pattern 110 ′, other resonance characteristics that interfere with the antenna characteristics of the antenna module are applied. Can be formed.

Hereinafter, a specific structure of the present invention for preventing the resonance phenomenon that interferes with the antenna characteristics will be described.

The insert inserted into the connector module 300 receives an electrical signal from the mobile terminal 100 to output audio data. That is, in order to receive the electrical signal, the connector module 300 connects the injector with a main circuit board (not shown) mounted inside the mobile terminal 100.

The connector module 300 is a circuit board 310 and the insertion space 320 having a plurality of signal lines for the electrical connection between the main circuit board (not shown) and the earjet. And a connector body 320 forming a '). The plurality of signal lines extend from the circuit board 311 to the connector body 320 and are electrically connected to the injector. At least a portion of the circuit board 310 and the connector body 320 in which the plurality of signal lines are formed may be disposed to overlap the antenna pattern 110 ′.

Specifically, referring to FIG. 2A, the connector module 300 includes the connector body 320 and the circuit board 310.

The connection terminal part 322 is in contact with the second to

fourth contact areas

412, 413, and 414 of the injector 400. The connection terminal portion 322 protrudes from the inner surface of the connector body 320 to cover the second to

fourth contact regions

412, 413, and 414 formed on one region of the outer circumferential surface of the cylindrical injector 400. Each can be made to wrap. Meanwhile, an end portion of the connection terminal portion 322 is fixed to the connector body 320, protrudes to the outer surface of the connector body 320, and is electrically connected to the plurality of signal lines, respectively. The number of contact areas is not limited thereto. An insulating part (not shown) is formed between the contact areas to insulate them, and a handle part 420 that can be grasped by a hand is formed to insert the contact area.

The switching terminal unit 321 is in contact with the first contact region 411 of the injector 400. The switching terminal unit 321 may be disposed in the deepest region of the connector body 320, but the arrangement position of the switching terminal unit 321 and the connection terminal unit 322 is not limited to those illustrated in the drawing.

The switching terminal part 321 includes a support part 321a, a fixing part 321b, a contact clip part 321c, and a spring part 321d. The support part 321a includes a hole so that the injector 400 can be inserted, and one region is fixed to the connector body 320. The fixing part 321b protrudes in one direction from the support part 321a and surrounds the outer circumferential surface of the ear jet 400. One area of the fixing part 321b is bent to be in contact with the first contact area 411.

The contact clip portion 321c may be formed of a c-clip bent in a direction opposite to the fixing portion 321b. The contact clip portion 321c and the fixing portion 321b are formed on different surfaces of the support shaft 321e protruding from the support portion 321a. The support shaft 321e extends in the one direction. The support shaft 321e is fixed to the support part 321a to be movable in a direction crossing the one direction.

The spring portion 321d is disposed on the support shaft 321e in a direction crossing the one direction. The spring part 321d is configured to elastically support the support shaft 321e and the inner surface of the connector body 320.

Referring to FIG. 2B, in the switching terminal part 321 according to the present embodiment, the contact clip part 321c protrudes from the

support shafts

321e and 321e, and the protruding shape of the spring part 321d. ) Can be made of a structure that wraps. In this case, in the state in which the spring portion 321d is extended, the end of the contact clip portion 321c does not contact the signal line, and when the spring portion 321d is compressed, the contact clip portion 321c The signal line may be in contact.

One signal line of the plurality of signal lines is formed in the connector body 320 to be in contact with the contact clip portion 321c. Although not illustrated in detail, the one signal line may extend to be formed on an inner circumferential surface of the connector body 320.

2A and 2B, in the state where the injector 400 is not inserted into the fixing part 321b, the contact clip part 321c is connected to the connector body by the elastic force of the spring part 321d. It is not in contact with the inner circumferential surface of the 320 and the signal line.

On the other hand, when the ear jet 400 is inserted into the fixing part 321b, the space formed by the fixing part 321b is expanded, and the support shaft 321e is close to the inner surface of the connector body 320. Move to lose. In this case, the spring portion 321d is compressed.

The first contact region 411 of the ear jet 400 is connected to the one signal line by the contact clip part 321c. A contact terminal is formed on the circuit board 310 to connect with the plurality of signal lines, respectively.

The first contact terminal 312a and the plurality of second contact terminals 312b are formed on the circuit board 310. The plurality of second contact terminals 312b are electrically connected to the second to fourth contact regions 411 of the ear jet 400, respectively. The first and

second contact terminals

312a and 312b transmit various kinds of signals transmitted from the mobile terminal 100 to the earjet 400. The ear 400 may output audio data according to the various types of signals.

That is, the signal line is connected to or disconnected from the contact clip part 321c by insertion and withdrawal of the injector 400. The signal line extending from the circuit board 310, the contact clip part 321c and the fixing part 321b connected thereto are connected only when the injector 400 is inserted into the connector module 300. . That is, the signal line is disconnected from the contact clip part 321c and the fixing part 321b when the injector 400 is drawn out from the connector module 300.

Meanwhile, the length of the antenna pattern 110 ′ may be formed to be similar to the length of the signal line and the fixing part 321b. In this case, another resonance characteristic that interferes with the resonance characteristic of the antenna pattern 110 ′ may be generated by the signal line and the fixing part 321 b, thereby degrading antenna function.

However, when the injector 400 is separated by the connector module 300, the connection between the signal line and the fixing part 321b is blocked. Therefore, a path of the conductive member having a length similar to that of the antenna pattern 110 'is not formed. Therefore, the antenna characteristic can be prevented from being blocked.

The circuit board 310 further includes a switch SW connected to the first contact terminal 312a. The switch unit SW will be described below with reference to FIGS. 5A and 5B.

3 is a graph for comparing antenna efficiency.

Graphs 1 and 2 correspond to a case in which a structure formed to be in contact with each contact region of the earjet is always in contact with a signal line. Graph 1 is a graph showing antenna efficiency in a state in which a radio frequency signal blocking inductor is not formed in a contact terminal formed on the circuit board, and graph 2 is about the first and

second contact terminals

312a and 312b. This graph shows a case where a 100 nH radio frequency signal blocking inductor is formed. Comparing graphs 1 and 2, if no inductor is formed, antenna efficiency of the frequency band of about 1710 MHz to about 1900 MHz is lowered.

On the other hand, graph 3 shows the state in which the inject 400 is drawn out from the connector module 300 in the present invention. Comparing graph 3 with respect to graph 2 above, it is confirmed that antenna efficiency of all frequency bands is improved.

That is, when the ear ejection 400 is terminated, the signal line is connected to the component (the contact clip portion 321c, the fixed clip portion 321b in the present invention) coupled with the ear ejection, the antenna It does not form a metal path similar to pattern 110 '. Therefore, it does not generate a resonance that interferes with the wireless performance, it is possible to improve the efficiency of the wireless performance when the audio output function is unnecessary.

2A and 4, the connector module 320 and the circuit board 320 according to the present exemplary embodiment are substantially the same except for the number of the switching terminal units 321. Therefore, redundant description is omitted.

The connector module 320 may include a plurality of switching terminal units 321. This may vary depending on the number and length of the antenna patterns 110 '. For example, the connector module 320 may include two switching terminal portions 321, and the two switching terminal portions 321 may be alternately arranged with the connection terminal portion 322, but the arrangement is the antenna. It depends on the length of the pattern 110 'and is not limited to that shown in the figure.

Referring again to FIG. 2A, the mobile terminal according to the present embodiment includes a switch unit SW formed on the first contact terminal 312a electrically connected to the switching terminal unit 321. The switch unit SW may be made of SPST, or may include a first switch or a second switch made of SPDT having an inductor of about 100 nH.

The controller 180 controls the switch based on whether the switching terminal unit 321 contacts the signal line by insertion and withdrawal of the injector 400. The switch determines whether the inductor is connected to the first contact terminal 312a.

FIG. 5A illustrates a case in which the inject 400 is drawn out, and FIG. 5B illustrates a case in which the inject 400 is inserted into the connector module 300.

Referring to FIG. 5A, when the contact between the signal line and the switching terminal unit 321 is terminated, the controller 180 shorts the signal line through the first switch, and the first contact through the second switch. The inductor is connected to the terminal 312a.

When an inductor is connected to the first contact terminal 312a through the second switch, the first contact terminal 312a is shorted. Accordingly, resonance does not occur that interferes with the antenna performance. In this case, a function of outputting audio data through the eject cannot be performed.

Meanwhile, referring to FIG. 5B, when the inject 400 is inserted into the connector module 300, contact between the signal line and the switching terminal part 321 of the connector module 300 is terminated. The display unit 151 may output an icon 401 indicating that the inject 400 is connected to the mobile terminal 100. Accordingly, the controller 180 controls the first switch SPST or the second switch SPDT.

When the first switch SPST is mounted on the first contact terminal 312a, the controller 180 connects the signal line to the first contact terminal 312a. Accordingly, the audio output function through the first contact terminal 312a is performed.

Meanwhile, when the second switch SPDT is mounted on the first contact terminal 312a, the controller connects the signal line and the first contact terminal 312a without the inductor. Accordingly, the audio output function can be performed.

5C shows a state in which an inductor is not connected to any one of the plurality of contact terminals (for example, the first contact terminal 312a in FIG. 2A), and the second graph shows any one of the above contact terminals. The inductor (about 100nH) is connected to the contact terminal of. This corresponds to a state in which the inject 400 is drawn out from the connector module 300.

According to the present embodiment, as shown in FIG. 5A, an inductor of about 100 nH is connected while the inject 400 is drawn out from the connector module 300. Accordingly, the antenna efficiency as shown in graph 2 can be obtained, which can be confirmed to be improved than the antenna efficiency of graph 1.

In case of Graph No.1, it shows the state that resistance of one contact terminal is set to 0 ohm for audio output function. Therefore, if audio output function is performed or not (the eject is pulled out from the connector module). In both cases, a relatively low antenna efficiency is obtained.

That is, according to the present embodiment, when the audio output function is performed through the ear eject, a connection state for performing the audio output function is formed, and when the audio output function is unnecessary, the antenna efficiency can be improved by connecting the inductor. Can be.

The present invention described above can be embodied as computer readable codes on a medium in which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like. This also includes those implemented in the form of carrier waves (eg, transmission over the Internet). In addition, the computer may include the controller 180 of the terminal.
