Description

Mobile phone with auxiliary loudspeaker {MOBILE PHONE HAVING SUB-LOUD SPEAKER}

The present invention relates to a mobile phone including a dual speaker in which the earpiece and the loudspeaker are integrally implemented.

1 and 2, the mobile phone 10 including the conventional dual speaker has an earpiece 22 and a loudspeaker 24 integrated with each other, thereby making the dual speaker integrated with the mobile phone. In other words, the inner surface of the folder to which the LCD is attached is implemented an earpiece 22 to handle the general voice, the outer surface of the folder is implemented a loudspeaker 24 to handle the complex voice.

However, in the case of a mobile phone including a conventional dual speaker, when the mobile phone operator displays the game or video media through the LCD attached to the inner side of the folder, the sound effects related to the game or the video media are fixed and installed on the outer side of the folder. Since the loudspeaker 24 is radiated in the opposite direction of the mobile phone operator, there is a disadvantage that effective acoustic listening is difficult.

In addition, the conventional mobile phone including a dual speaker reproduces the media sound through one loudspeaker 24, so if the user wants a stronger sound or three-dimensional sound has a disadvantage that can not meet the expectations.

The present invention is to solve the problems of the prior art, the dual speaker is made of a mobile phone and detachable and the dual speaker is rotatably attached to the mobile phone can be inverted the position of the earpiece and the position of the loudspeakers as needed I want to provide a mobile phone.

In addition, the present invention is to provide a mobile phone that can be stably fixed to the dual speaker to the mobile phone by having an elastic projection, and can easily conduct the position of the earpiece and the loudspeaker by having a gripping projection.

In addition, the present invention is to provide a mobile phone that can easily connect the earpiece and the loudspeaker to the mobile phone through the hollow shaft (hollow shaft) by the rotation axis formed in the dual speaker. do.

On the other hand, the present invention has an auxiliary loudspeaker, and the input and output connector speaker terminal formed on the input / output connector (I / O connector) so that the auxiliary loudspeaker can be inserted and operated so that the user can obtain a stronger volume with a three-dimensional sound You may want to provide a mobile phone.

Dual speaker 100 has an upper end 140 and both side portions 130 are inserted into the dual speaker receiving groove 210 and the lower end 150 is open to the outside, the upper end 140 and the lower end 150 of the dual speaker 100 ), The outer surface diameter of the cylinder constituting the both side portions 130 of the dual speaker 100 is equal to the inner diameter of the cylinder constituting the both side portions 212 of the dual speaker receiving groove 210 or Make it slightly smaller.

Referring to FIG. 3, an elastic protrusion 132 protrudes and is formed on the side portion 130 of the dual speaker 100. The elastic protrusion 132 is introduced into the side portion 130 of the dual speaker 100 during the external pressure action, and is formed to protrude from the side portion 130 to be inserted into the fixing groove 212H when the external pressure is removed. Therefore, the left and right side portions of the elastic protrusions 132 and the fixing grooves 212H may be chamfered inclined portions so that the elastic protrusions 132 are easily separated from the fixing grooves 212H when the rotational force is applied to the dual speaker 100. It is preferable.

Referring to FIG. 3, the upper end 140 of the dual speaker 100 is formed as an outer surface of the hollow sphere. Dual speaker 100 has an upper end 140 and both side portions 130 are inserted into the dual speaker receiving groove 210 and the lower end 150 is open to the outside, the upper end 140 and the lower end 150 of the dual speaker 100 ), The outer diameter of the hollow sphere forming the upper end 140 of the dual speaker 100 is the same as the inner diameter of the hollow sphere forming the upper end (not shown) of the dual speaker receiving groove 210. Make it slightly smaller.

Referring to FIG. 3, the rotating shaft 142 protrudes and is formed at the upper end 140 of the dual speaker 100. The rotating shaft 142 is inserted into the rotating groove (not shown) and is formed to be rotatable. On the other hand, the rotating shaft 142 is formed of a hollow shaft (中空 軸).

Referring to FIG. 3, the FPCB 144 connected to the earpiece 112 and the loudspeaker 122 has a rotating shaft 142 formed in a hollow shaft and a rotating groove formed in the dual speaker receiving groove 210. It is connected to the cell phone through (not shown).

Meanwhile, referring to FIG. 4, a gripper 152 is installed at the lower end 150 of the dual speaker 100. The gripper 152 protrudes and is formed to easily apply a rotational force to the dual speaker 100.

The I / O connector 310 will be described.

Referring to FIG. 3, an input / output connector 310 is installed at a lower end of the main body 300 for connection with the outside. Meanwhile, an input / output connector 310 is connected to the auxiliary loudspeaker 400 to form an input / output connector speaker terminal 312 for operating the auxiliary loudspeaker 400.

Auxiliary loudspeaker 400 will be described.

3 and 4, the auxiliary loudspeaker 400 is connected to the input / output connector speaker terminal 312 and is formed to operate together with the loudspeaker 122.

Therefore, the auxiliary loudspeaker 400 has an auxiliary loudspeaker connector 410 that can be inserted into the I / O connector 310. In addition, the auxiliary loudspeaker connector 410 is formed with an auxiliary loudspeaker terminal 412 that can be connected to the input and output connector speaker terminal 312, the auxiliary loudspeaker terminal 412 is a media signal for controlling the auxiliary loudspeaker 400 It is connected to the line (Media Signal Line).

Hereinafter, the operation of the above-described embodiment will be described.

3 and 4, when using the earpiece 112, the earpiece 112 is located on the inner surface of the folder 200, while listening to the sound effect of the loudspeaker 120 while watching the LCD for the game, etc. In this case, the loudspeaker 120 is positioned on the inner surface of the folder 200. At this time, when the gripping protrusion 152 is applied by hand to impart rotational force, the protrusion protrusion 142 contacts the fixing groove 212H so that an external pressure acts on the protrusion protrusion 142 so that the protrusion protrusion 142 is dual. The dual speaker 100 is easily rotated because it is drawn into the side part 130 of the speaker 100 and is separated from the fixing groove 212H. When the dual speaker 100 rotates 180 degrees and the position of the earpiece 112 and the loudspeaker 122 is changed, the protruding protrusion 142 is inserted into the fixing groove 212H again, and when the rotational force is removed, the dual speaker ( 100) is stably fixed to the mobile phone. On the other hand, the FPCB 144 is flexible, so that even if it rotates 180 degrees, the earpiece 112 and the loudspeaker 122 can be connected to the mobile phone without a circuit.
