Description

TELECOMMUNICATIONS EQUIPMENT FOR EXCLUDING A NOISE}

The present invention relates to an electronic device, and more particularly to a communication device having a speaker for transmitting sound to the outside.

In general, a mobile phone is used for a telephone call while moving, and a speaker for listening to a call and a microphone for inputting a voice are installed. The reception sound received by the communication device is transmitted to the outside through a speaker formed of a plurality of holes on the front of the body as shown in FIG. 1, and the user attaches an ear to the speaker to listen to the sound from the speaker.

However, when using the mobile phone of the above-described structure, it is impossible to obtain a good call due to noise when the surroundings are not quiet.In case of making a call while keeping the speaker close to one ear to block the surrounding noise, the human body may be harmed by electromagnetic waves. You can wear

Although a noise canceling circuit may be added and used to remove the noise of the received sound during the call, it is not a fundamental noise blocking method that reflects environmental factors and thus does not effectively block the disturbance of ambient noise on the received sound.

The object of the present invention is to provide a communication device that not only effectively blocks ambient noise, but also protects a user from electromagnetic waves of the communication device.

Is fixed). When the spring 280 is in an equilibrium state, the protrusion 120 remains partially inserted into the insertion groove 240, and the protrusion 120 is moved into the insertion groove 240 when the breaker 100 is moved. Is moved.

Guide paths 260 are formed on the side surfaces of the pedestal 220. The guide path 260 guides and fixes the movement of the wire end portion protruding from the inner wall of the breaker 100 through the guide hole 166. FIG. 8 is an enlarged view of the guide path 260 formed on the pedestal 220 of FIG. 4. Referring to FIG. 8, the guide path 260 has an upper locking part 262, a descending ramp 266, a lower locking part 264, and a lifting ramp 268. The upper catching part 262 is disposed above the guide path 260 to a position where the wire 180 is fixed when the breaker 100 is positioned to protrude a predetermined length from the body 10. The lower locking portion 264 is disposed below the upper locking portion 262 to a position where the wire 180 is fixed when the breaker 100 is inserted below the body 10. On one side of the upper catching portion 262 and the lower catching portion 264, a descending slope 266 is formed to guide the movement of the wire 180 from the upper catching portion 262 to the lower catching portion 264, the other side A lifting ramp 268 which guides the movement of the wire 180 from the lower locking portion 264 to the upper locking portion 262 is formed.

The down ramp 266 has a first inclined portion 266a, a first vertical portion 266b, a second inclined portion 266c, a third inclined portion 266d, and a second vertical portion 266e. The first inclined portion 266a extends downward from the top catching portion 262 to be inclined to one side, and the first vertical portion 266b extends vertically downward from the first inclined portion 266a. The second inclined portion 266c extends down from the first vertical portion 266b to be inclined in a direction opposite to the first inclined portion 266a, and the third inclined portion 266d extends from the second inclined portion 266c. It extends upward to be inclined in the same direction as the first inclined portion 266a and is connected to the lower locking portion 264. The second vertical portion 266e is a portion extending downward between the second slope portion 266c and the third slope portion 266d in parallel with the first vertical portion 266b.

The lifting ramp 268 has a first inclined portion 268a, a vertical portion 268b, and a second inclined portion 268c. The first inclined portion 268a extends downward from the top catching portion 262 to be inclined to the other side, and the vertical portion 268b extends vertically downward from the first inclined portion 268a. The second inclined portion 268c is a portion inclined to branch from a predetermined position of the vertical portion 268b and to be connected to the lower locking portion 264.

9A to 9C are diagrams sequentially illustrating a path along which the wire 180 is moved along the guide path 260. When the breaker 100 is kept in a state of protruding a predetermined length to the upper surface of the body 10, the spring 280 is in an equilibrium state, the end of the wire 180, as shown in Figure 9a the upper catch Located at 262. When a force is applied to the breaker 100 from the outside, the breaker 100 is gradually inserted into the body 10. The spring 280 is compressed by the protrusion 120, and the end of the wire 180 is separated from the upper catching portion 262 by the first inclined portion 266a, the first vertical portion 266b, and the second inclined portion ( 266c), and the second vertical portion 266d. When the force is removed from the breaker 100, the end of the wire 180 is elevated upward by the elastic force of the spring 280 and moved along the third inclined portion 266e, and then as shown in FIG. 264). As a result, the breaker 100 is maintained in a state in which a considerable length is inserted into the body 10. When the force is applied to the breaker 100 again, the end of the wire 180 is moved downward along the second inclined portion 266c to be positioned at the lower end of the vertical portion 266b, and the spring is removed when the force is removed. After moving along the vertical portion 266b and the first inclined portion 266a by the elastic force of 280, it is fixed to the upper locking portion 262 as shown in FIG. 9C. As a result, the breaker 100 protrudes from the body 10 by a predetermined length.

FIG. 10A is a view illustrating a state in which a part of the breaker 100 is inserted into the body 10 when the mobile phone is not in use, and FIG. 10B is a cross-sectional view of part 'A' of FIG. 10A. 11A is a view showing a state in which the circuit breaker 100 protrudes from the body 10 when using a mobile phone, and FIG. 11B is a cross-sectional view of the portion 'B' of FIG. 11A. 10A and 10B, when the mobile phone is not used, the breaker 100 has a predetermined length inserted into the body 10, the spring 280 is compressed, and the end of the wire 180 has a lower end portion 264. Is located in. Then, when the user presses the upper surface of the cover 300 to apply a force, as shown in Figure 11a and 11b the end of the wire 180 is moved to the upper hook portion 262 while maintaining the spring 280 in an equilibrium state The breaker 100 is protruded from the body 10 by a predetermined length. The user places one ear on the upper surface of the cover 300 and listens to the received sound from the speaker 20.

Therefore, since the human body does not directly touch the speaker 20, the influence of the electromagnetic wave is reduced, and as shown in FIG. 12, external noise is blocked when the received sound from the speaker 20 is transmitted to the user, thereby maintaining a comfortable call state. Can be.

In the present embodiment, the noise blocking unit 30 has a structure in which a predetermined length is protruded from the body 10 when the mobile phone is used, and a portion is inserted into the body 10 when the mobile phone is not used. . However, the noise blocking unit 30 may be fixedly installed in a protruding state so as to surround the speaker 20 from the body 10 at all times.

According to the present invention, when a user uses a communication device, a certain interval is secured between the communication device and the human body, thereby minimizing the human body being affected by electromagnetic waves.

In addition, according to the present invention, a breaker is inserted into the body during non-calling and easy to carry during non-calling, and during a call, the breaker protrudes from the body to block ambient noise so that a comfortable call state can be maintained.
