[0001] The present invention relates to a waterproof structure of a micro speaker,

The present invention relates to a water repellent structure of a micro speaker having improved water repellency, and more particularly, to a water repellent structure of a micro speaker in order to improve the water repellency of the micro speaker, an additional hydrophilic mesh which can easily absorb and discharge water and moisture And a water repellent structure of a micro speaker which improves the water repellency which can prevent moisture and the like from being absorbed by the hydrophilic network again and to be discharged to the outside, thereby preventing malfunction of the micro speaker due to moisture or the like.

Generally, in order to test the water repellency of a speaker, a water repellent portion capable of blocking the inflow of moisture to the front and rear surfaces of the sound transmission portion is stacked in multiple layers as in Korean Utility Model Registration No. 20-0443432, I broke through the part and prevented the water from going in the direction of the speaker.

However, even if the water-repellent water-repellent layer having a water-repellent property is laminated as described above, a part of moisture or water penetrates through the water-repellent portion due to water pressure or the like and flows into the inside of the speaker. Water or moisture, The water-repellent part or the like is not discharged to the outside, and remains on the inside of the micro-speaker, so that the efficiency of the speaker is lowered or broken.

In this case, the water-repellent portion serves to prevent water or moisture from being absorbed by water or moisture and to prevent water or moisture from passing through the water-repellent portion. So that some water or moisture is introduced into the speaker.

Then, after removing the speaker from the water, it is necessary to shake the speaker or use a separate device to discharge some water or moisture that has flowed into the inside of the speaker back to the outside. If the speaker is taken out of the water, The water or moisture is blocked by the water-repellent portion due to the water-repellent portion that simply blocks the inflow of water or moisture, so that the water located inside the speaker is not properly discharged and the efficiency of the speaker is lowered or malfunctions A problem has occurred.

A water repellent structure of a micro speaker that improves water repellency of the present invention includes a micro speaker that outputs sound, a first adhesive member that is positioned on a surface of a micro speaker in a direction in which sound is output, A second adhesive member located on a surface of the water-repellent mesh; and a hydrophilic mesh member located on a surface of the second adhesive member and sucking water and moisture to the outside while discharging the moisture and water, The hydrophilic mesh can be quickly and easily discharged to the outside by placing the hydrophilic mesh which can be discharged while absorbing the moisture to the surface, so that the micro speaker can be durably deteriorated due to moisture or moisture, And so on.

Then, the hydrophilic mesh and the second adhesive member are attached in the form of 'ㅁ' shape having a center space or in the shape of '11' in the direction of the rim of both upper and lower sides or the rim of both sides of the left and right, So that moisture and moisture in the wall or corner of the micro speaker can be quickly absorbed and discharged easily.

This design places a hydrophilic mesh that can drain while absorbing water to the surface of the micro speaker, so that the water flowing into the micro speaker can be quickly and easily discharged to the outside, and the durability of the micro speaker due to moisture, It is advantageous to reduce the efficiency, breakage, and malfunction.

Then, the hydrophilic mesh and the second adhesive member are attached in the form of 'ㅁ' shape having a center space or in the shape of '11' in the direction of the rim of both upper and lower sides or the rim of both sides of the left and right, It is possible to absorb water and moisture in the wall or corner of the micro speaker more quickly and to discharge it easily.

FIG. 2 is an exploded perspective view showing one embodiment of first and second adhesive members and a hydrophilic mesh of a water repellent structure of a micro speaker having improved water repellency according to the present invention. FIG.
3 to 4 are exploded perspective views showing another embodiment of the first and second adhesive members and the hydrophilic mesh of the water repellent structure of the micro speaker having improved water repellency according to the present invention.

The configuration of the present invention for achieving the above object will be described as follows.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, a micro-speaker water-repellent structure 100 having improved water repellency of the present invention is formed with a micro speaker 10 installed in a portable terminal such as a cellular phone and outputting sound.

Here, the micro speaker 10 is generally used in a portable terminal, and a detailed description thereof will be omitted.

The first adhesive member 20 having adhesive properties is attached to the upper surface or the front surface of the micro speaker 10 along the surface in the direction in which sound is output.

A water repellent mesh 30 (which prevents water or moisture from entering the micro speaker 10 on the surface, such as a front surface of the first adhesive member 20 (a direction in which sound is output) or an upward direction Is formed so as to cover the entire area in the direction in which the sound is emitted from the micro speaker 10.

Here, the water-repellent net 30 is generally formed of a fabric or a metal material to prevent water or moisture from flowing into the water-repellent net 30, and thus a detailed description thereof will be omitted.

The water repellent mesh 30 may be formed to have the same overall surface area as the front surface of the micro speaker 10 so as to cover the entire front surface of the micro speaker 10 so that water or moisture can not easily be introduced into the micro speaker 10.

A second adhesive member 40 having an adhesive property is attached to the front surface or the upper surface of the water repellent net 30 (the direction in which the sound is output).

Here, the first adhesive member 20 and the second adhesive member 40 are similar to double-sided tapes that are currently in use, and include a structure in which both the first adhesive member 20 and the second adhesive member 40 are attached, It is obvious that what is used for bonding is not described in detail.

2 to 4, the first adhesive member 20 and the second adhesive member 40 are attached to the surface of the micro speaker 10 in the direction of the sound output portion, The adhesive member 20 and the second adhesive member 40 are not adhered to the entire area of the micro speaker 10 but are attached to both sides of the ' Quot; 11 " shape on both sides of the " 11 " direction.

This is because as the area of the first adhesive member 20 and the second adhesive member 40 becomes wider, the adhesiveness increases, but the contact with other materials such as dust increases by an increased area, It is preferable to minimize the area of the first adhesive member 20 and the second adhesive member 40 because it affects the sound output from the micro speaker 10 or the like.

A hydrophilic mesh 50 is attached to the front surface or the upper side of the second adhesive member 40 so that water or moisture can be quickly absorbed and discharged to the outside.

When the hydrophilic mesh 50 is formed on the front or the upper side of the water repellent mesh 30, the hydrophilic mesh 50 is not formed like the entire area of the water repellent mesh 30, Like shape in which a space is formed in the center of the water-repellent mesh 30, or a space is formed in the middle of the water-repellent mesh 30 in the shape of '11' like the left and right edges of the water- So as to be formed on both sides.

When the hydrophilic mesh 50 is located on the front or upper side of the water-repellent mesh 30, it is preferable to maintain the water-repellent mesh 30 at a minimum of 10% .

This is because if the area of the hydrophilic mesh 50 is small, the water absorbing ability to absorb water or the like becomes low, and the water introduced into the micro speaker 10 can not be properly drawn out. Therefore, Is at least 10% with respect to the total area of the water repellent mesh (30).

It is preferable that the hydrophilic mesh 50 is not more than 50% of the total area of the water repellent mesh 30 in order to discharge most of the water or moisture that has flowed into the micro speaker 10, The water introduced into the micro speaker 10 is not positioned at the center of the micro speaker 10 but moves to the wall surface or the corner of the micro speaker 10 by the structure of the micro speaker 10, And moves to the surface of the micro speaker 10 to which the mesh 30 and the hydrophilic mesh 50 are attached and moves to the surface of the micro speaker 10, The area of the hydrophilic mesh 50 is at most 50% of the entire area of the water-repellent mesh 30 so that the hydrophilic mesh 50 is not positioned at the central portion where no water flows, .

In addition, the hydrophilic mesh 50 can be prevented from being positioned at the central portion where no water flows, thereby preventing the hydrophilic mesh 50 from being wasted.

The water or moisture located at the rim of the micro speaker 10 contacts the water-repelling radiation 30 and immediately comes into contact with the hydrophilic network 50. Due to the characteristics of the hydrophilic network 50, So that water or moisture remaining in the micro speaker 10 is discharged to the outside.

In addition, the hydrophilic mesh 50 is formed of a woven fabric or a synthetic resin material which is capable of absorbing water quickly and absorbing moisture quickly and discharging it to the outside, and therefore, a detailed description thereof will be omitted.

Hereinafter, the operation according to the preferred embodiment of the present invention will be described.

First, when a test is performed to check the waterproof property of a portable terminal or the like having a built-in micro speaker 10, or when a user mistakenly puts the water into the water, a part of water or moisture is absorbed into the hydrophilic net 50 Flows through the formed space to the micro speaker 10 while passing through the water repellent net 30.

When the user shakes the portable terminal or the like to remove the water flowing into the micro speaker 10, the water moves to the wall or the corner according to the structure of the micro speaker 10 by the swing, And moves to the surface of the speaker 10 and touches the water repellent net 30 to touch the hydrophilic net 50 attached to the water repellent net 30.

Therefore, the water or moisture remaining in the micro speaker 10 directly absorbs moisture or water such as oil, but does not directly contact the hydrophilic mesh 50 formed to discharge water or moisture directly to the outside, .

Therefore, water or moisture introduced into the micro speaker 10 can be easily discharged to the outside due to the hydrophilic mesh 50, so that malfunction or breakage of the micro speaker 10 due to water or moisture can be prevented .

Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. It is obvious to those who have knowledge of.
