The present invention relates to a sound quality adjustable slim speaker case.

A speaker is a combination of a unit, a case and a network.

When listening to music, the electric signal generated from the audio amplifier is transmitted to the unit via a cable, which is a terminal block, and the sound is generated from the unit's cone and the front surface of the cone paper. Is located outside the case, the sound of the mid and high is generated in the front direction, and the sound generated from the back of the unit paper (Cone Paper) located inside the case is amplified by the inside of the case. .

In this case, since the internal structure of the speaker case and the plate material forming the case generate different sounds (sounds), the quality of the speaker may be evaluated according to the case structure.

Many consumers are interested in the dedicated speakers for the home theater system.

General audio has two channels of two speakers and four channels of four speakers. Home theater systems are currently commercially available in 5.1-channels consisting of six speakers, 6.1-channels consisting of seven speakers, and 7.1-channels consisting of eight speakers.

As the number of speakers increased, the speaker case manufactured with a clunky design with a conventional stand-up structure has many limitations on the use of speaker installation spaces, and requires high-quality residential, commercial, cultural and art spaces, and religion. In the interior of the group meeting space and the arts education space, the artist cannot satisfy the artistic sensibilities of the consumers who want to express the space beautifully, and overlooks the aesthetic value as a speaker case suitable for the atmosphere of the space.

In addition, past and present speaker cases are fixed type in which the internal structure of each manufacturer is arbitrarily determined. The consumer's preference for different sounds is not considered.

In other words, consumers can not replace the speaker because they do not satisfy the sound quality of the speaker once purchased without using other expensive devices, but simply by the simple act of the speaker case itself. This is frequent.

As a result, a large number of buyers purchase foreign-imported speakers with high brand recognition at a high price, which is a huge waste of foreign currency.

However, the sound quality of Korean and foreign speakers does not seem to be much different. Nevertheless, consumers pay a high price for the smallest subtle sound quality.

This section describes the structure of a speaker case, which is one of the factors that determine the sound quality of minute differences.

10, 11, 12, 13, and 14 are bass reflex type, flat type, rear open type, closed type, and labyrinth type names given by the internal structure of a speaker case.

The attached bass reflex type speaker case of FIG. 10 is a method of extracting only the bass sound by using a pipe from the inside of the case. Sound) is not well generated.

The flat speaker case of FIG. 11 is advantageous in that the sound is very natural, and the disadvantage is that the bass is not generated well and the unit is not used much at present because a large unit needs to be mounted.

The rear open speaker case of FIG. 12 has advantages and disadvantages for sufficiently reproducing bass, and thus, the characteristics of the rear open speaker case are greatly changed according to the place where the sound is placed.

The enclosed speaker case of FIG. 13 is a completely enclosed structure in which only the front sound (sound) of the speaker is reproduced. The disadvantage is that the volume inside the case should be as large as possible to generate bass. Not suitable for home use.

The maze-shaped speaker case of FIG. 14 attached to the speaker draws sound coolly but dislikes a lot of people because of the distortion of the sound. Especially high treble dies.

As a result, most of the conventional speaker cases have many advantages, but they also account for a large part of the disadvantages, and thus, they do not satisfy the individual's various tastes about the artistic sentiment and the sound of the users. The upgraded speaker case is needed.

The present invention has been made to solve the shortcomings of the existing speaker case as described above, in particular, the present invention has been studied for many years to slim down to express the beauty of the wall space designed in a unique design, especially the speaker sound (sound The purpose is to provide a very practical wall-mounted slim speaker case equipped with a function that can be adjusted at any time to suit your taste.

       The present invention is a speaker case of a structure that can generate a high quality sound (sound) by using a rectangular rectangular case of the case that is designed to be attached to the wall of the case is wide, the square of the side portion is narrow, that is, a frame shape To provide.

      The speaker unit is mounted on the speaker case, and a plurality of holes of a predetermined size are drilled on the back plate, the top, bottom, left and right side plates of the case, and the holes are opened or closed with a stopper or a diaphragm made of rubber, thereby closing the air inside the case. As the flow rate increases and decreases, the sound quality and volume of the mid-low bass band can be changed to be closer to the taste of the consumer.

       And in order to make the case slim as close as possible to the case's front and back plates, the ferrite magnet (magnet) attached to the back of the unit is pushed to the outside of the case's back plate and the actual sound (sound) is generated. The Cone Paper part of the unit is placed inside the case for slimming.

      In addition, after drawing or printing an image of 1mm thick or less fabric, leather, etc., which is made to prevent air from being firmly fixed to the square frame on the wide front panel of the case, and drawing on the surface of the leather, it is attached to the front edge of the unit. It is fixed within 5mm from the circular edge to form a thin air layer, and the sound generated from the front of the unit vibrates the double sounding board on which the air layer, pictures and photos are drawn simultaneously. Sound) is characterized by having a function of a beautiful double sounding board which is further amplified.

       The structure and operation of the speaker case according to the present invention and the sound (sound) according to the present invention will be described with reference to FIG.

      1. Select speaker case board

The main base material of the speaker case (1) of the present invention is selected from hard, deformation-free wood board, fiber board, carbon fiber board, glass fiber board, metal board, synthetic resin board, press paper board, within 15mm thickness use.

In the present invention, an important matter is to select a plate whose sound is as good as possible.

As the board is selected, the board is heavy and thick to make heavy sounds, and light and thin to make clear and light sounds.

For example, if you think of drums, drums, drums, drums, drums, cellos, violins, lyre, gayageum, bells, etc., the volume of the barrels, the relationship between wood, leather and metal, and the weight of wood It is a sounding instrument that produces different sounds produced by combining.

The speaker case is also a sort of tone instrument. In particular, the thinner the thickness of the material, the more sensitive the sound (sound) of the material. It can be seen that the selection of materials is the most basic act of making luxury.

In the embodiment of the present invention described below, the thickness of the material was 6 mm. This is to minimize the side thickness of the speaker case manufactured by the present invention (see Fig. 4).

In addition, according to the experiment of the inventors of the present invention, a clearer and lighter sound (sound) was generated than a speaker case manufactured with a thickness of about 12 mm. (The result of listening to the sound (sound) under the same conditions)

2. Machining the front plate of the speaker case

Referring to the processing of the front plate (front part) 2 with reference to Fig. 3, first, the plate is cut to a size of 60 cm and 60 cm, and then fixedly attached to the 4 to 5 inch bass unit 8. Holes 1 to 2 inches in diameter are drilled at the top to fix the 4 to 5 inch diameter holes 10 and the 1 to 2 inch sized treble unit 9 at the center.

3. Back plate (back part) processing of speaker case

Referring to the process of the back plate (back part) 3 in connection with Fig. 5, first, the front plate 2 is cut to the same size.

The part of the ferrite magnet (15) located at the rear of the bass unit (8) and the treble unit (9) is projected out of the case (1) to maximize the front plate (2) and the rear plate (3) of the case (1). In order to make it close and slim, a hole 12, a terminal attachment hole 13, and a sound quality control hole 17 of about 80 to 90 mm are drilled in the center of the case 1.

Experimental results show that blocking all of the holes 17 with a rubber stopper 19 significantly decreases the bass, and increases the bass when opened. In other words, the bass sound generated from the back of the unit cone paper (16) vibrates the inside of the case 1 while vibrating the inside of the case 1, and when opened a lot, one or two opens a small amount of bass.

This is a speaker case backplate 3 with no structure, which is designed to be adjusted so that the case 1 itself alone can be adjusted to the preferences and tastes of the users' different sounds without paying extra costs.

4. Processing and completion of the speaker case top, bottom, left and right panels (side part)

FIG. 6 is a diagram illustrating the plate structure of four surfaces of the top, bottom, left, and right plates 4, 5, 6, and 7 positioned on the side surface.

24 holes 18 are drilled in each of 6 holes on each side by cutting the hole 18 having a diameter of 20 mm by cutting the size of 3.2 cm in width and 60 cm in length. The hole 18 is a sound passage and the characteristics according to the use of the 24 holes 18 are the same as those described in the back plate 3 described above.

4, 5, 6, 7 plates on the side, combined with the front plate (2) and the back plate (3), the thickness of the square side 2cm, front rear area 3,600 as shown in Figure 1 A cuboid slim speaker case 1 having a cm 2 and a case internal volume of 7,200 cm 3 is completed.

The proper volume inside the case 1 to satisfy the ringing action, which is the first function as the speaker case 1, is proportional to the size of the bass unit 18 to be mounted in the case 1.

The present invention is that the front part of the case (1) is wide, the square of the side portion is narrow, that is, designed to be attached to the wall as a picture frame shape that can generate high-quality sound (sound) with the sealed rectangular case (1) of the cube Structure. The bass unit 8 and the treble unit 9 are mounted on the speaker case 1 and fixed to the back plate 3 and the top, bottom, left, and right plates 4, 5, 6 and 7 of the case 1. By opening and closing several holes 17 and 18 in size and opening or closing some or all of these holes 17 and 18 with rubber stoppers 19 or diaphragms, there is a large flow of air in the space inside the case 1 As the vibration decreases, the sound quality and volume, which are caused by the vibration and decrease, in particular, the bass band, can be changed so as to be close to the taste of the consumer.

And the ferrite magnet attached to the rear part of the bass unit (8) and the treble unit (9) in order to make the case (1) slim as close as possible to the front plate (2) and the back plate (3) of the case (1) (Ferrite magnet: magnet) The paper of the bass unit (8) and the treble unit (9) that protrudes the outside of the case back plate (3) and generates actual sound (Cone Paper) The part 16 is positioned inside the case 1 to realize slimming.

5. Look at another embodiment of the present invention to amplify the sound by performing another sounding plate function and to express the artistic.

7 is for explaining the double ring 14.

Draw or print an image such as a picture or a picture on the surface of a fabric having a thickness of 1 mm or less, which is made to prevent air from being firmly fixed to the rectangular frame 20 on the wide front plate 2 of the case 1 Then, it is fixed within 5 mm from the circular edge (21) attached to the front edge of the bass unit (8) and the treble unit (9) to form a thin air layer to form a thin air layer (8) And double sounding board 14 in which sound (sound) generated from the front part of the high-pitched unit 9 vibrates the double sounding board 14 on which the air layer, pictures, photos, etc. are drawn at the same time. To have the function of.

This is an advanced application that improves the false stereotype of the grille, as opposed to the simple grille structure, which is designed to allow very easy passage of air mounted on the surface of existing speaker cases.

The inventor of the present invention, while studying a method of generating a better sound (sound) by modifying the structure of the speaker case (1) itself, instead of the front plate (2) to remove and remove the front plate (2) as shown in Figure 8 When the double sounding plate 14 is hermetically fixed, the front part of the bass unit 8 and the treble unit 9 which are located outside the case 1 made of a plate is in the case 1.

The speaker case (1) of this structure is equipped with a conventional general cone (Cone) type unit to listen to music.

Allowing for sufficient reproduction of the sound. A powerful sound was formed by vibrating enough to visually confirm that the wide double sound board 14 of the front vibrated.

As described in detail above, the sound quality adjustable slim speaker case provided by the present invention is a speaker case designed in such a way that a conventional general high output unit can be mounted, which is not accessible at all in various conventional speaker cases. High power unit of more than 200 watts can be installed, and the direction of sound (sound) is very wide as shown in Fig. 2, and the structure of the existing speaker case which is becoming smaller is improved. It is designed so that users with different preferences can easily adjust the sound (sound) that they want without any device and the world famous painting is beautifully expressed on the front of the speaker case. To meet demand In particular, it is a wall-mounted speaker case that maximizes space utilization, and it is another artwork that satisfies the artistic sensibilities of consumers who want to express all spaces beautifully. It is enough to receive.

In addition, the present invention, if the case material is attached to the wall while maintaining a constant distance from the wall using a speaker mounting bracket with a vibration-resistant rubber in the method of Figure 2 after the production of a very light new material of the case material selected by the case itself Like a separate percussion instrument, the entire cube cube becomes a masterpiece that functions as a sounding board.
