Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application, and inclusion in this section is not admitted to be prior art.

In general, a speaker is a sound device that converts electrical signals into vibrations of a diaphragm and generates small waves in the air to radiate sound waves.

In addition, as is widely known, a speaker is a device that converts an input electrical signal into a sound signal, and has a structure capable of vibrating a diaphragm according to an electrical signal. The vibration force is given by electromagnetic force, and the electric wire is configured to generate sound by vibrating the diaphragm with electromagnetic force, which is the force received in the magnetic field where the force of the magnet ends.

A more detailed look at the general configuration of such a speaker and its operating principle is as follows.

A frame is provided, and a magnetic circuit unit and a sound generating unit are respectively installed on the lower surface side and the upper surface side of the frame. The magnetic circuit part has a plate, a magnet and a yoke, and the sound generator part has a diaphragm and a voice coil.

There have been various devises to solve this problem, and among them, Registration Utility Model Publication No. 20-0143256 describes the upper plate coupling structure of the speaker, and details are as follows.

The contents described in the publication are related to the structure of the upper plate of the speaker, and the technical configuration is that a frame is connected and installed around the upper end of a yoke, and a magnet is integrally bonded to the inside of the yoke, and a through groove is formed on the upper side thereof. An upper plate formed through the central portion is coupled, a voice coil is installed at the periphery of the plate, and the upper end thereof is coupled to a vibration plate connected to the frame, and a gasket is coupled to the upper end periphery of the vibration plate. It relates to an upper plate coupling structure of a speaker, characterized in that a guide inclined to the side is installed at the periphery of the lower end of the upper plate.

The above design is to prevent leakage of the adhesive used for bonding the magnetic and the plate and the decrease in bonding force due to undistribution. This is also fixed using an adhesive, so that the bonding strength between the magnetic and the plate still decreases, and the adhesive leaks. There is a problem that can be.

The number of terminals 130 may be variously formed, but it is for supplying power. As shown in FIG. 1, it is preferable that the terminal 130 is formed of two terminals 130 consisting of a positive electrode and a negative electrode.

In addition, the shape of the terminal seating portion 120 may be formed differently according to the shape of the terminal fixing portion 140 to be seated.

For example, when the terminal fixing part 140 is a square plate, the terminal mounting part 120 must also be formed in a square shape corresponding thereto, and when the terminal fixing part 140 is a circular plate, the terminal mounting part 120 ) Should also be formed into a circular plate accordingly.

However, since the upper surface of the terminal seating portion 120 and the lower surface of the terminal fixing portion 140 must be in contact and coupled, each surface is preferably formed in a flat shape in consideration of the fixing force caused by surface contact.

If it is not flat, the lower surface of the terminal fixing unit 140 and the upper surface of the terminal seating unit 120 cannot be seated on a flat surface, so the coupling with the power terminal is unstable, and the current delivered to the voice coil 20 is unstable. There is a problem that an error occurs in the operation of the product.

Therefore, as shown in FIG. 1, the general shape of the terminal fixing part 140 is formed as a rectangular plate, and accordingly, the terminal seating part 120 is also formed in a rectangular shape, but it is preferable that the upper surface is formed in a flat shape. .

The shape and coupling method of the terminal 130 coupled to the terminal fixing part 140 are various.

However, as shown in FIG. 2, terminal fixing holes 142 are formed on both sides of the terminal fixing part 140, and terminal fixing protrusions 132 corresponding thereto are formed on one side of the terminal 130, It is mutually forced.

This has the advantage of shortening the working time by simplifying the bonding method through blocking rather than fixing by the conventional soldering method.

The shape of the terminal fixing protrusion 132 and the terminal fixing hole 142 may be variously formed, such as a conical shape, a rectangular parallelepiped, and a regular cube, but it is preferable to be formed in the shape of a rectangular parallelepiped in consideration of mutual bonding force.

In addition, as shown in FIG. 2, the terminal fixing protrusion 132 has to be fixedly contacted with one end of the voice coil 20 to transmit a current from an external power source to the voice coil 20, which is formed of a conductor. desirable.

As shown in FIGS. 1 and 2, locking protrusions 123 are formed on both sides of the terminal seating portion 120 to protrude upward.

The length of the locking protrusion 123 may be variously formed, but at least it should be formed to have a larger value than the thickness of the terminal fixing portion 140 to be seated and coupled.

If it is formed to have a value smaller than the thickness of the terminal fixing part 140, the locking protrusion 123 does not contact both sides of the terminal fixing part 140, resulting in a problem that the terminal fixing part 140 cannot be fixed. do.

Since both sides of the terminal fixing part 140 are caught and fixed to the locking protrusion 123, it is preferably formed in at least two or more, but symmetrically formed on the upper surface of the terminal mounting part 120.

The material of the speaker frame 100 may be a cold rolled steel sheet, abs resin, aluminum, or the like.

However, in consideration of the uniformity of the thickness, good shape, smooth surface, low cost, and high productivity, it is preferable to be formed of a cold rolled steel sheet.

In addition, it is preferable that the speaker frame 100 and the terminal seating portion 120 are integrally formed through injection to reduce cost.

As shown in FIG. 2, a magnetic expansion plate 200 is stacked on the upper surface of the speaker frame upper plate 101 to be combined.

As shown in Figure 2, the first through hole 203 is formed in the center of the magnetic expansion plate 200.

The shape of the first through hole 203 may be variously formed, such as a circle, a rectangle, and a square, but a yoke 403 to be described later is inserted into the first through hole 203, and the inserted yoke 403 is 1 It is inserted through the through hole 203 to the opening hole 103, the shape of the first through hole 203 is formed in the same shape as the shape of the opening hole 103 formed in the speaker frame top plate 101. It is desirable.

The shape of the magnetic expansion plate 200 may be variously formed, such as a rectangle, a square, and a circle.

However, in general, the magnetic plate 300 (magnet) used in the speaker is formed in a rectangular shape, and the magnetic plate 300 is stacked on the upper surface of the magnetic expansion plate 200 to be combined. When considering, the magnetic expansion plate 200 is preferably formed in a rectangular shape.

As shown in FIG. 2, the magnetic expansion plate 200 is laminated and coupled to the upper surface of the speaker frame upper plate 101.

The magnetic force expansion plate 200 functions to expand the range of the vibration of the voice coil 20 by expanding a region of a magnetic field in which a current flows through the voice coil 20. The magnetic expansion plate 200 may be formed in various ways such as a circle, a rectangle, and a square shape, and is laminated and combined on the upper surface of the speaker frame upper plate 101, and a magnetic plate 300, which will be described later, is laminated on the upper surface of the magnetic expansion plate 200. It is preferable that both sides are formed in a plane when considering the coupling fixing force and stability that are combined.

If the plane is not formed, a contact surface is not uniform when each component is stacked and bonded, so that the bonding force is weak and the vibration of the voice coil 20 is not properly caused.

In addition, as shown in FIG. 2, a plurality of auxiliary holes 205 may be formed on both sides of the first through hole 203 of the magnetic expansion plate 200.

This is to improve the coupling fixing power with the speaker frame.

Accordingly, as shown in FIG. 2, an auxiliary fixing protrusion 107 corresponding to the position and shape in which the auxiliary hole 205 is formed may be formed on the speaker frame upper plate 101.

Thereby, the auxiliary fixing protrusion 107 of the speaker frame upper plate 101 is fitted into the auxiliary hole 205 of the magnetic expansion plate 200, and each surface is coupled while making contact.

The shape of the auxiliary hole 205 and the auxiliary fixing protrusion 107 may be formed in various ways, but the shape of the auxiliary hole 205 is to correspond to the shape of the auxiliary fixing protrusion 107. It is preferable to be formed in a shape.

The material of the magnetic expansion plate 200 may be formed in various ways. In consideration of the function of expanding the magnetic field, it is preferable to be formed of a conductor.

A second through hole 303 is formed in the center of the magnetic plate 300 as shown in FIG. 2.

This is the yoke 403 of the sound plate 400 to be described later is inserted and fixed, and its size and shape should be formed to correspond to the shape and size of the yoke 403.

For example, when the shape of the yoke 403 is formed as a regular cube or a rectangular parallelepiped, the shape of the second through hole 303 may be formed in a square or rectangular shape corresponding thereto.

However, the voice coil 20 is coupled to the yoke 403, and it is generally and preferable to be formed in a cylindrical shape for optimizing the vibration of the voice coil 20. Correspondingly, the second through hole 303 is It is preferable that the shape is formed in a circular shape.

The magnetic plate 300 is stacked on the upper surface of the magnetic expansion plate 200, and the lower surface of the sound plate 400 to be described later is in contact with the upper surface of the magnetic plate 300 to be coupled. It is preferable that the lower surface is formed in a plane.

In addition, the magnetic plate 300 is preferably formed of a material having magnetic properties, since a magnetic field must be formed around the voice coil 20 to which power is supplied.

2 and 4, a yoke 403 is formed to protrude in one direction at the center of one surface of the sound plate 400.

The shape of the yoke 403 may be variously formed, but when considering that the voice coil 20 is generally produced in a hollow cylindrical shape, and is used by being wound or inserted into the yoke 403, the yoke (403) It is also preferable to be formed in a cylindrical shape.

If the outer surface of the yoke 403 is formed in the form of a hexahedral system (cube, cuboid) formed to protrude outward, there is a risk that the voice coil 20 wound or inserted in the yoke 403 will be damaged due to friction with the protruding part. have.

In addition, the length of the yoke 403 may be formed in various ways, as shown in the figure, in a state in which the yoke 403 penetrates the first and second through holes 303, the magnetic force expansion plate 200 and the magnetic force When the plate 300 is laminated and coupled to the speaker frame upper plate 101, when the magnetic expansion plate 200 is laminated on the upper surface of the speaker frame upper plate 101 and the magnetic plate 300 is laminated thereon, the speaker frame upper plate It is preferable that it is formed to have a value greater than the height from 101 to the upper surface of the magnetic plate 300.

This means that the yoke 403 integrally penetrates the first through hole 203 of the magnetic expansion plate 200 and the second through hole 303 of the magnetic plate 300 and the opening hole 103 of the speaker frame top plate 101 It is to first fix the combination of each speaker component by inserting it.

If it is formed smaller than the above-described value, a problem occurs in that the entire coupling of the speaker component members cannot be stably fixed.

The shape of the sound plate 400 may be variously formed, such as a circle, a rectangle, and a square, but it is preferably formed in a rectangle in the same shape as the magnetic plate 300 and the magnetic expansion plate 200.

This is to improve the bonding force due to surface contact by securing an area in which the lower surface of the sound plate 400 is in contact with the upper surface of the magnetic plate 300 as much as possible.

In addition, the lower surface of the sound plate 400 must be formed in a plane.

If it is not a flat surface, the range of the surfaces that are in contact with each other is reduced, and the fixing force and stability of the coupling may be weakened.

As shown in FIG. 3, a space 505 is formed inside the cover part 500.

In this space 505, as shown in FIG. 3, the magnetic expansion plate 200, the magnetic plate 300, and the sound plate 400 laminated and coupled to the speaker frame top plate 101 are integrally accommodated, and are coupled to the speaker frame. The above-described coupling is fixed by pressing in the direction of the ground.

The shape of the cover part 500 may be variously formed, such as a rectangle or a square, but as described above, the outer surfaces of each speaker component members stacked and coupled to the space 505 of the cover part are accommodated (covered). It is preferable to be formed in a rectangle corresponding to the shape of the speaker constituent members.

In addition, in order to form a space 505 inside the cover part, as shown in FIGS. 2 and 3, a first wall 501 is formed symmetrically on one side of the cover 500 and a second wall is formed on the other side. (503) should be symmetrically formed.

Since the cover part 500 has a rectangular shape, it is preferable that the horizontal length of the first wall 501 is longer than the horizontal length of the second wall 503.

In addition, the horizontal length of the first wall 501 and the second wall 503 should be formed to be larger than the horizontal lengths of members such as the magnetic plate 300.

If the width of the first wall 501 and the second wall 503 is smaller than the width of the speaker component members such as the magnetic plate 300, the speaker frame top plate 101 is located in the space 505 of the cover part. There is a problem in that the members to be laminated and bonded to each other cannot be accommodated, and thus the bonding force to be achieved by the present invention cannot be improved.

The vertical length (height) of the first wall 501 and the second wall 503 is the height when the magnetic plate 300, the magnetic expansion plate 200, and the sound plate 400 are laminated and coupled to the speaker frame upper plate 101 It is preferably formed to have a value equal to or greater than.

If it is formed to have a small value, the laminated members cannot be accommodated in the space 505, resulting in a problem that the bonding force is not improved.

This cover part 500 is coupled to the speaker frame 100, as shown in FIGS. 2 and 3.

As for the bonding method, various methods such as bolts and nuts, adhesives, etc. may be formed.

However, in order to simplify the working process and shorten the working time, it is desirable to be combined by fitting.

To this end, as shown in FIG. 2, fitting holes 109 are formed symmetrically on both sides of the upper plate of the speaker frame 100, and fittings corresponding to the fitting holes 109 on both lower sides of the cover part 500 The protrusion 105 is formed symmetrically.

The shape and number of the fitting holes 109 and the fitting protrusions 105 may be variously formed, but they are forcibly fitted to each other and are combined. The shape and number of the fitting holes 109 are the shape of the fitting protrusions 105 It is preferable to be formed to correspond to the number of and.

It is preferable in terms of cost reduction that the fitting hole 109 is integrally produced when the speaker frame 100 is manufactured, and the fitting protrusion 105 is integrally produced through injection manufacturing when the cover part 500 is manufactured.

The material of the cover portion 500 may be formed in various ways such as plastic, elastic body, etc., and it is preferable to be formed of plastic that is convenient to use because the production cost is low and light.

In addition, referring to FIGS. 3 and 4, a pressing protrusion 506 for pressing the sound plate 400 may be formed on the inner upper portion of the cover part 500. The magnetic plate 300 may be formed of a magnetic material, that is, a magnet or ferrite. Even if a magnetic material such as ferrite is molded to a certain standard, a thickness variation occurs due to shrinkage.

When the magnetic plate shakes inside the speaker, noise may occur and accurate voice data cannot be transmitted. Therefore, it is necessary to be fixedly coupled inside the speaker.

To this end, when the cover part 500 is fitted with the speaker frame 100, a pressing protrusion 506 formed on the cover part 500 presses the sound plate 400, and the lower part of the sound plate 400 The magnetic plate 300 located in it can also be firmly supported.

Two or more of the pressing protrusions 506 may be formed on the inner upper portion of the cover part 500, and may be formed at a position symmetrical with respect to the center of the cover part 500.

When the pressing protrusion 506 fixedly supports the sound plate 400, if the sound plate 400 is not supported symmetrically, there is a fear that the sound plate 400 may shake, and a plurality of pressures at a position symmetrical with respect to the center of the cover part 500 It is preferable to form the protrusion 506. For example, as shown in FIGS. 3 and 4, two or four pressing protrusions 506 are formed, but are positioned in the corner directions of the cover part 500 based on the center of the cover part 500, respectively. Can be formed. Through this, the sound plate 400 and the magnetic plate 300 may be supported and fixed to maintain the horizontal.

In addition, one or more through-holes are formed on the upper part of the cover part 500, and the pressure protrusion 506 is located in a through-hole formed on the upper part of the cover part 500, and one side is the cover part 500 ) Can be formed to be connected.

When the pressure protrusion 506 presses and supports the sound plate 400, it may have a certain elasticity depending on the material of the pressure protrusion 506, but there is a risk of damage if the pressure is continuously applied.

Therefore, as shown in FIGS. 3 and 4, the pressing protrusion 506 is positioned in the through hole formed in the cover part 500, and one side is formed to be connected to the cover part 500, so that it has a certain elasticity. can do.

5 to 7, a center fixing part 507 is formed in the center of the inner upper surface of the cover part 500, and a central groove part 405 is formed on the upper surface of the sound plate 400, so that the sound plate 400 ) Can be fixedly coupled with the central groove 405.

In order to reproduce sound source data accurately and uniformly, the centers of the components of the speaker must match. In the prior art, the center of each component was aligned and bonded through a member capable of fixing the center, but this connection structure is coupled without bonding, and a central groove part 405 is formed on the sound plate 400 , A center fixing part 507 is formed on the cover part 500 to be fixedly coupled to each other to align the center of each component. When the center of the sound plate 400 is fixed by the cover part 500, the center of the magnetic plate 300 and the magnetic expansion plate 200 may also be fixed by the yoke 403 formed on the sound plate 400.

Since the center fixing part 507 must be closely coupled with the center groove 405 formed on the sound plate 400, it may be formed to correspond to the shape of the center groove 405, and when closely coupled, the center Since the groove portion 405 is filled with air or the like, resistance to coupling may occur.

Accordingly, as shown in FIGS. 4 and 5, an opening is formed in the center of the center fixing part 507 to facilitate coupling.

In addition, as shown in FIG. 7, the edge of the central fixing part 507 may be formed to be inclined in the center direction, so that it may be easily combined with the sound plate 400, and the central groove part of the sound plate 400 ( 405) In addition, it may be formed to correspond to the inclined surface formed on the edge of the center fixing portion 507.

1 and 2, a plurality of hooks 115 are vertically formed on both sides of the speaker frame lower plate 110 in an upward direction.

The shape and number of the hooks 115 may be variously formed.

However, when the speaker frame 100 is coupled to the speaker housing and assembled, the hook 115 is engaged with a locking groove (not shown) formed in the speaker housing. It is desirable to be formed correspondingly.

Accordingly, the operator can couple the speaker frame 100 to the speaker housing through the hook 115 without the need for connecting members such as bolts, thereby reducing working time, convenient work, and reduced production cost.

In this way, the speaker cover is not connected by a conventional soldering or bonded, but a pressing protrusion and a center fixing part are formed on the cover part, thereby providing an advantage of strengthening the coupling fixing force of each speaker component member.
