Description

Noise Reduction in Flip-Opening and Flip-type Cell Phones

The present invention relates to a flip type mobile phone including CT-2, HHP, PCS, etc., and more particularly, to a noise reduction structure during flip operation.

Typically, mobile phones include bar-type, flip-type, and holder-type mobile phones. Flip type and holder type mobile phones are becoming more common than bar type. Flip-type or holder-type mobile phones are advantageous for miniaturization and are becoming more common because they can play a role as a sound reflector, not only collecting sound but also protecting keys.

Such a flip type mobile phone is shown in FIG. Referring to the drawings,

The flip type mobile phone is composed of a main body 1000, a flip 2000, and a hinge device (not shown in the figure) connecting the main body and the flip cover.

An antenna device 1010 is positioned at the top of the main body 1000, and an earpiece 1020 including a speaker is positioned below the antenna device, and an LCD unit 1030 is mounted below the earpiece. In addition, a keypad 1040 including a plurality of number keys, function keys, and the like is disposed under the LCD part, and a microphone device 1060 is installed at the bottom of the body 1000. The microphone device 1060 has a configuration in which the hinge device is installed.

Therefore, when the flip 2000 is opened and closed according to whether the call is made, the flip performs the rotation operation about the rotation center axis A1 of the hinge device.

However, in the process of performing the opening and closing operation of the flip according to the call, severe noise is generated in the process of closing the flip in the open state. In other words, if the force to close by a predetermined angle by the force of the hinge device is provided, the flip is closed to the main body, the noise is generated during the collision between the flip and the main body.

Noise was generated by sudden surface contact between the flip side and the top of the body. Such noise has been caused as a cause of lowering the user's feeling by providing discomfort to the user.

The present invention has been made to solve the above-described problems, the object of the present invention provides a noise reduction structure during flip opening and closing that can minimize the noise generated when flip-opening, flip-type mobile phone.

Another object of the present invention is to provide a noise reduction structure during flip open / close which protrudes at least one dot rib in place on the upper surface of the main body.

It is still another object of the present invention to provide a noise reduction structure during flip opening / closing in which a point contact is a surface contact generated between the flip and the main body at the time of flip opening and closing.

In order to achieve the above objects, the present invention is a flip-type mobile phone consisting of a main body having an upper surface, a flip, and a hinge device for mechanically connecting the main body and the flip,

At least one dot-shaped rib protrudes from the upper surface of the main body in order to minimize noise generated during flip opening and closing operations.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing each of the drawings, only the same components have the same reference numerals as much as possible even if shown on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

As shown in FIGS. 3 and 4, the flip type mobile phone is composed of a hinge device (not shown in the drawing) connecting the main body 1000, the flip 2000, and the main body 1000 and the flip cover 2000. As shown in FIG.

An antenna device 1010 is positioned at the top of the main body 1000, and an earpiece 1020 including a speaker is positioned below the antenna device, and an LCD unit 1030 is mounted below the earpiece. In addition, a keypad 1040 including a plurality of number keys, function keys, and the like is arranged below the LCD part, and a microphone device 1060 is installed at the bottom of the main body 1000. The microphone device 1060 has a configuration in which the hinge device is installed.

Therefore, when the flip 2000 is opened or closed according to whether or not the call is made, the flip performs the rotation operation about the rotation center axis A1.

At this time, the dot-shaped rib 10 protrudes at a predetermined position of the main body 1000. At least one dot-shaped rib 10 protrudes. When the flip 2000 performs the opening and closing operation of the hinge device with the rotation center axis, the flip 2000 contacts the upper surface of the main body 1000. The flip 2000 performs point contact with the upper end of the dot rib 10 by the dot rib 10. .

As a result, the present invention has a structure in which the noise is reduced by realizing the surface contact of the flip to the point contact during the flip opening and closing operation.

On the other hand, in the present invention is limited to the embodiment protruding at least one dot-type rib 10 at a predetermined position of the main body 1000, the dot-type rib by protruding to the flip cover, it is possible to implement the surface contact by point contact.

On the other hand, in the detailed description of the present invention has been described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.

As described above, the present invention is effective in minimizing noise generated during flip-opening operation in a flip-type mobile phone.
