Description

High performance slim speaker {HIGH PERFORMANCE SLIM SPEAKER}

The present invention relates to a high-performance slim speaker, and more specifically, to a high-performance slim speaker having a slim structure in the direction of a TV surface, in which a reflector is integrated into a high-performance speaker including an upper frame portion, and the reflector is directly bonded to an upper magnet portion through bonding, so that the entire thickness of the magnetic portion including the lower magnet portion, the upper magnet portion, and the plate can be utilized as an upper and lower vibration space of the vibrating portion.

FIG. 1 is a plan view, a side cross-sectional view, a plan view, and a side cross-sectional view of a speaker according to the prior art, each showing an enlarged view of a major part thereof, and FIG. 2 is a drawing showing an enlarged view of a major part of a speaker according to the prior art.

As shown in FIGS. 1 and 2, a conventional speaker comprises a frame (1), upper and lower magnets (3) formed of rings and provided inside the frame (1), a plate (2) interposed between the upper and lower magnets (3), and a yoke (4) positioned below the lower magnet (3), which together form a magnetic circuit.

Here, the voice coil (6) provided near the outer periphery of the upper and lower magnets (3) is composed of a bobbin and a coil wound on the outer periphery of the bobbin. The bobbin surrounds the outer periphery of the upper and lower magnets (3) and is configured such that the central portion thereof is supported on the frame (1) by a damper (7) so as to enable vibration in the up-and-down direction. In addition, the upper end of the bobbin is coupled with a cap (9), and the bobbin is supported by a cone paper (8) between the upper end of the bobbin and the portion where the bobbin is coupled with the damper.

In addition, a tinsel wire (10) is connected between the terminal (5) to which an externally supplied sound signal and power are applied and the lead wire of the coil, thereby providing the coil with a sound signal to be reproduced by the speaker.

In the case of the conventional speakers illustrated in FIGS. 1 and 2, as TV designs become slimmer, speaker thickness also becomes slimmer in recent times. Accordingly, the "A" space (the space between the damper (7) and the frame (1), i.e., the free space of the damper (7)) and the "B" space (the space between the tinsel wire (10) and the damper (7), i.e., the free space of the tinsel wire (10)) of FIG. 1 become smaller and smaller, and thus securing the amplitude for the up-and-down movement of the voice coil (6) becomes increasingly restricted. In this situation, if the speaker thickness becomes slimmer, there arises a problem that the performance deteriorates compared to a thick speaker.

In this regard, according to a prior patent document, Republic of Korea Utility Model Registration No. 20-0371619 (registered on December 21, 2004, title of the invention: Thin speaker with damper installed), "the present invention relates to a thin speaker with a damper installed, comprising: a base body including a receiving portion opened upward; an electromagnetic assembly installed in the receiving portion and including at least a yoke, a magnet, a pole piece, and a voice coil; a vibrating membrane connected so that its edge surrounds an edge of the receiving portion of the base body; a damper having a wave-shaped cross-section installed at the center of the vibrating membrane; and a voice coil of the electromagnetic assembly installed on a side of the vibrating membrane opposite to the receiving portion and attached to an outer edge of the damper, and a technical configuration in which the center of the damper is fixed to the electromagnetic assembly."

However, although the utility model patent publication disclosed above attempted to propose a slim, flat speaker, it did not solve the problem that the space "A" and "B" of Fig. 1 described above, that is, the free space of the damper and the free space of the tinsel wire, became smaller and smaller, and thus securing the amplitude for the up-and-down movement of the voice coil (6) became increasingly restricted.

Furthermore, in the utility model publication, there was no awareness of the problem at all regarding a high-performance slim speaker having a slim structure in the direction of the TV surface, in which a reflector considered in the present invention is integrated into a high-performance speaker including an upper frame portion, and the reflector is directly bonded to the upper magnet portion through bonding, so that the entire thickness of the magnetic field portion including the lower magnet portion, the upper magnet portion, and the plate can be utilized as an upper and lower vibration space of the vibrating field portion.

Utility Model Registration No. 20-0371619 (registered on December 21, 2004), Flat Speaker with Damper Patent Publication No. 10-2181415 (registered on November 16, 2020), High-performance slim speaker Patent Publication No. 10-2212327 (registered on January 29, 2021), high-performance slim speaker

The present invention has been created to solve the above-described problems, and an object of the present invention is to provide a high-performance slim speaker having a slim structure in the direction of a TV surface, in which a reflector is integrated into a high-performance speaker including an upper frame portion, and the reflector is directly bonded to an upper magnet portion through bonding, so that the entire thickness of the magnetic field portion including the lower magnet portion, the upper magnet portion, and the plate can be utilized as an upper and lower vibration space of the vibrating field portion.

In order to achieve the above object, the present invention provides a high-performance slim speaker for a TV, which comprises an upper assembly part and a lower assembly part, and has a slim structure in the direction of a TV surface, wherein the lower assembly part comprises: a lower frame part (1-1) which covers the lower part of the speaker and has an opening in the upper and lower direction; a yoke (4) which is positioned on the lower frame part (1-1) and covers the opening of the lower frame part (1-1); a lower magnet part and an upper magnet part (3) which are positioned on the yoke (4); and a plate (2) interposed between the lower magnet part and the upper magnet part (3); wherein the upper assembly part comprises: an upper frame part (1-2) which covers the upper part of the speaker and has an opening in the upper and lower direction; a reflector (12) which covers the opening of the upper frame part (1-2); a protrusion which protrudes downward from the reflector (12); a bobbin which is attached while wrapping the lower magnet part and the upper magnet part (3) and the plate (2) inside; A voice coil (6) wound on the bobbin and vibrating the bobbin up and down according to an electric signal applied thereto; a supporter portion (11) formed so that one end of the voice coil (6) is supported on an outer surface and the other end is extended so as to be supported by a cone paper (8); a cone paper (8) connected to the supporter portion (11) and vibrating up and down by receiving the up and down vibration of the voice coil through the supporter portion (11); And a damper (7) connecting between the cone paper (8) and the protrusion, and connecting between the cone paper (8) and the upper frame (1-2); wherein the vibration unit including the bobbin, the voice coil (6), the supporter unit (11), the cone paper (8) and the damper (7) is positioned further outside the center of the magnetic unit in the circumferential direction than the magnetic unit including the yoke (4), the lower magnet unit and the upper magnet unit (3), and the plate (2), so that the vibration unit can secure a larger free space in which it can vibrate up and down.

Here, the reflector (12) is mounted on the reflector mounting portion provided on the upper frame portion (1-2), and is combined while covering the opening of the upper frame portion (1-2) and the upper portion of the speaker, and the portion where the upper frame portion (1-2) and the reflector (12) are combined forms a flat plane, so that the reflector is integrated into the high-performance speaker including the upper frame portion (1-2).

In addition, the reflector (12) is directly bonded to the upper magnet section (3) through bonding, so that the entire thickness of the magnetic section including the lower magnet section, the upper magnet section (3), and the plate (2) can be utilized as the upper and lower vibration space of the vibration section.

In addition, the reflector (12), together with the protrusion, the cone paper (8) and the damper (7), forms a reflection space between the reflector (12), the protrusion, the cone paper (8) and the damper (7), so that air vibration formed within the reflection space through the up-and-down vibration of the cone paper (8) can be converted into a vertical direction and provided by changing the direction toward the outer circumference of the high-performance slim speaker.

In addition, the damper may have a ring shape connecting between the cone paper (8) and the protrusion and connecting between the cone paper (8) and the upper frame (1-2), and may be formed of a conductive metal material.

In addition, the damper may be formed of a plastic material, a synthetic resin material, a rubber material, or a urethane material that has a ring shape connecting between the cone paper (8) and the protrusion and connecting between the cone paper (8) and the upper frame (1-2), and taking a curved shape.

In addition, the supporter portion (11) may be formed by n supporter bridges (n is a natural number greater than or equal to 2) formed radially at the same angle, with one end supporting the voice coil (6) on the outer surface and the other end being extended to support the cone paper (8). When n is 3, three supporter bridges are formed at a 120-degree angle.

In addition, it includes a terminal (5) that receives power and an audio signal from the outside; and a tinsel wire section (10) that connects the terminal and the voice coil and transmits the audio signal to the voice coil.

In addition, the tinsel wire portion includes a (+) terminal tinsel wire and the (-) terminal tinsel wire.

In addition, it is preferable that the high-performance slim speakers are placed one on each side of the lower rear of the TV, and that the reflector forms part of the rear of the TV.

According to the high-performance slim speaker according to the present invention,

First, the reflector is integrated into a high-performance speaker including an upper frame portion, and the reflector is directly bonded to the upper magnet portion through bonding, so that the entire thickness of the magnetic portion including the lower magnet portion, the upper magnet portion, and the plate can be utilized as an upper and lower vibration space of the vibrating portion.

Through this, it is possible to have a slimmer structure in the TV direction.

Second, the reflector, together with the projection, the cone paper and the damper, forms a reflection space between the reflector, the projection, the cone paper and the damper, so that air vibration formed within the reflection space through the up-and-down vibration of the cone paper is converted into a vertical direction and provided by changing its direction toward the outer circumference of the high-performance slim speaker.

Third, the vibrating section including the bobbin, voice coil, supporter section, cone paper and damper is positioned further outward in the circumferential direction from the center of the magnetic section than the magnetic section including the yoke, lower magnet section and upper magnet section, and plate, so that the vibrating section can secure more free space for up-and-down vibration.

Through this, it is possible to use a thicker magnetic material than before even in a slim speaker, so that despite being slim, performance is further improved, high output is obtained, and sound quality can be improved.

Fourth, recently, in slim displays, etc., there are many cases where speakers are also required to be slim. According to the present invention, even if implemented in slim flat-screen TVs, etc., the effect of not degrading performance can be obtained.

Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

FIG. 3 illustrates an installed appearance of a speaker assembled in a conventional TV, FIG. 4 illustrates a cross-sectional view of the left display portion of the drawing illustrated in FIG. 3, and FIG. 5 illustrates a characteristic configuration of a high-performance slim speaker according to a preferred embodiment of the present invention, compared to the speakers assembled in the conventional TV illustrated in FIGS. 3 and 4. In addition, FIG. 10 is a side cross-sectional view of a high-performance slim speaker according to a preferred embodiment of the present invention. Below, FIGS. 5 and 10 will be used for explanation.

As illustrated in FIGS. 5 and 10, a slim speaker for a TV according to an embodiment of the present invention, which has a slim structure in the direction of a TV surface, includes an upper assembly part and a lower assembly part. Here, the concepts of upper and lower in the upper assembly part and the lower assembly part refer to the concepts of lower and upper when the speaker is viewed separately, and it should be noted that, spatially, the front side of the TV, that is, the side where the viewer is located, is the lower part, and the back side of the TV, that is, the side where the wall on which the TV is installed is the upper part.

Additionally, as illustrated in FIG. 3, high-performance slim speakers may be placed one on each side of the lower rear of the TV. It is also possible for the reflector to form part of the rear (back) of the TV.

First, the lower assembly part includes a lower frame part (1-1), a yoke (4), a lower magnet part and an upper magnet part (3), and a plate (2).

Here, the lower frame part (1-1) covers the lower part of the high-performance slim speaker and has openings in the upper and lower directions. The lower frame part (1-1) forms a space for storing various components of the high-performance slim speaker inside together with the upper frame part (1-2). The yoke (4) is positioned on the lower frame part (1-1) and covers the opening of the lower frame part (1-1), and together with the lower magnet part and the upper magnet part (3), acts as a magnetic path for inducing magnetic flux in the magnetic circuit.

The lower magnet part and the upper magnet part (3) are positioned on the yoke (4) and usually have a circular shape, but may have various shapes such as a square shape, a track shape, or an oval shape in addition to a circular shape. The lower magnet part and the upper magnet part (3) may also be implemented as being divided into an internal magnetic body and an external magnetic body. The plate (2) is a configuration interposed between the lower magnet part and the upper magnet part (3).

Next, the upper assembly part includes an upper frame part (1-2), a reflector (12), a protrusion, a bobbin, a voice coil (6), a supporter part (11), a cone paper (8), and a damper (7).

Here, the upper frame part (1-2) covers the upper part of the high-performance slim speaker and has an opening in the upper and lower directions. It may have a circular opening as shown in Fig. 6. In addition, the upper frame part (1-2) may have a square opening, a track-shaped opening, or an oval opening in addition to the circular opening shape.

The reflector (12) is mounted on a reflector mounting portion (i.e., a wide groove portion that is slightly lowered and stepped down from the upper frame portion (1-2)) provided on the upper frame portion (1-2), so as to cover the opening of the upper frame portion (1-2) and at the same time cover the upper portion of the high-performance slim speaker, and are combined. Since the reflector (12) is mounted on the reflector mounting portion provided on the upper frame portion (1-2), the portion where the upper frame portion (1-2) and the reflector (12) are mounted and combined forms a flat plane (i.e., appears to be the same plane) when viewed from the outside, so that the reflector can be manufactured integrally with the high-performance speaker including the upper frame portion (1-2).

The reflector (12) receives sound from a high-performance slim speaker, that is, the sound coming from the front to the back of the TV (sound vibration in the direction perpendicular to the TV surface) and converts it to send it downwards from the TV, and is made of a steel plate or injection molded material. The remaining components of the high-performance slim speaker are assembled first, and the reflector is manufactured separately, installed in the reflector mounting groove, and then assembled by bolting.

In conventional speakers, a cover covering the opening of the upper frame is placed, and a reflector is placed separately from it. However, this has the problem that the thickness of the reflector, the thickness of the cover, and the distance between the reflector and the cover cannot be utilized, which reduces the degree of freedom and increases the thickness. However, the present invention is an invention in which even the thickness of the reflector is not a factor that reduces the degree of freedom. This is illustrated in Fig. 5.

In addition, the reflector (12) is directly bonded to the upper magnet section (3) described above by bonding with an adhesive or the like, so that the entire thickness of the magnetic section including the lower magnet section, the upper magnet section, and the plate (2) can be utilized as an up-and-down vibration space of the vibrating section. Here, the vibrating section includes a voice coil (6), a supporter section (11), and a cone paper (8) that vibrate up and down based on an acoustic signal (electrical signal) applied through a terminal, and is a configuration that induces vibration of air through up-and-down vibration to generate sound corresponding to the acoustic signal.

In addition, the reflector (12), together with the projection (a portion protruding from the lower surface of the reflector and connected to the damper), the cone paper (8) and the damper (7), forms a reflection space between the reflector (12), the projection, the cone paper (8) and the damper (7), thereby converting air vibration formed within the reflection space through the up-and-down vibration of the cone paper (8) into a vertical direction and providing it by changing its direction toward the outer circumference of the high-performance slim speaker.

Next, the bobbin is configured to be attached by wrapping the lower magnet part and the upper magnet part (3) and the plate (2) inside. The bobbin coil (6) is wound on the bobbin and vibrates the bobbin up and down according to an electric signal (sound signal) applied through the terminal. When an electric signal representing an sound signal is applied to the coil wound within the magnetic gap, a driving force is generated and it functions as a vibration source of the speaker. The material of the winding may be copper wire or aluminum wire, etc.

The supporter part (11) is configured to be extended so that one end of the voice coil (6) is supported on the outer surface and the other end is supported by the cone paper (8). The cone paper (8) is connected to the supporter part (11) and is configured to receive the up-and-down vibration of the voice coil through the supporter part (11) and vibrate up and down. It is possible to further improve the sound quality by forming it with a longitudinal or special material. The damper (7) is configured to connect between the cone paper (8) and the protrusion, and also between the cone paper (8) and the upper frame (1-2).

As described above, the vibrating section including the bobbin, the voice coil (6), the support section (11), the cone paper (8) and the damper (7) is positioned further outward from the center of the magnetic section in the circumferential direction (farther from the center) than the magnetic section including the yoke (4), the lower magnet section and the upper magnet section (3), and the plate (2), so that the magnetic section and the vibrating section are arranged at different positions in the plane, thereby ensuring a larger free space for the vibrating section to vibrate up and down without increasing the thickness.

Next, as illustrated in Fig. 7, the damper may have a ring shape connecting the cone paper (8) and the projection and connecting the cone paper (8) and the upper frame (1-2), and may be formed of a conductive metal material. Alternatively, as illustrated in Fig. 8, the damper may have a ring shape connecting the cone paper (8) and the projection and connecting the cone paper (8) and the upper frame (1-2), and may be formed of a plastic material, a synthetic resin material, a rubber material, or a urethane material having a curved shape. The damper is connected to the upper frame when a fitting structure is formed in the upper frame, and the damper is fitted into the fitting structure to be combined. At this time, it is possible to manufacture the damper using a plastic material, a rubber material, a urethane material, or the like to facilitate the fitting.

In addition, the supporter portion (11) may be formed by n supporter bridges (n is a natural number greater than or equal to 2) formed radially at the same angle, with one end supporting the voice coil (6) on the outer surface and the other end being extended to support the cone paper (8). When n is 3, three supporter bridges are formed at a 120-degree angle.

In addition, the terminal (5) of Fig. 10 is configured to receive power and an audio signal from the outside, and the tinsel wire section (10) is configured to connect the terminal (5) and the voice coil (6) to transmit an audio signal to the voice coil (6). This tinsel wire section includes a (+) terminal tinsel wire and the (-) terminal tinsel wire.

Through the above-described configuration, a slimmer structure is possible, and it is possible to use a magnet that is thicker than before, so that despite being slim, the performance is further improved, high output is obtained, and a high-performance slim speaker that can improve sound quality can be provided.

As described above, although the present invention has been described by means of limited embodiments and drawings, the present invention is not limited thereby, and various modifications and variations are possible by those skilled in the art to which the present invention pertains within the technical spirit of the present invention and the scope of equivalents of the claims to be described below.
