Description

Technical Field

[0001] The present invention relates to a speaker, and more particularly to a speaker, wherein a speaker box of the speaker has an inner space with an asymmetric cross-section, thereby improving the quality of sound. Background Art

[0002] Generally, a speaker includes a speaker unit that converts an electrical signal into a pneumatic signal, and an enclosure that houses the speaker unit and determines most of the sound quality.

[0003] This type of speaker can be roughly classified into a sealed type and a bass reflex type according to the form of the cabinet. The sealed type is formed by a structure in which the interior of the cabinet is completely sealed, and the sound is generated only by the sound waves generated from the front of the speaker unit. On the contrary, the bass reflex type is a form in which a duct connected to the interior of the cabinet is arranged, and the phase of the sound waves generated from the back of the cone of the speaker unit is reversed and discharged to the outside of the cabinet, which can improve the characteristics of the low-frequency sound range in particular.

[0004] As described above, the speaker cabinet not only functions as a shell that accommodates the speaker unit, but also performs the function of reflecting and attenuating the sound waves generated by the speaker unit. Therefore, it is an important component of the speaker that is no less important than the speaker unit.

[0005] Existing cabinets such as Figure 1a and Figure 1b As shown in the figure, the interior is formed symmetrically, and the sound emitted from the back of the speaker unit is reflected in a simple form on the inner wall of the box, which makes the reflected waves of a specific frequency increase abnormally, and finally the speaker emits a low-quality sound. Therefore, it is necessary to effectively configure the space inside the speaker with the speaker unit as the starting point.

[0009] Technical issues solved

[0010] The present invention is proposed to solve the above-mentioned needs and necessities, and its technical subject is to provide a speaker, wherein the speaker box of the speaker has an internal space with an asymmetric cross-section, which is used to suppress the abnormal increase of reflected waves of a specific frequency, so that the reflection of the sound pressure is evenly dispersed to a long distance while reducing the distorted reflection of the sound.

[0011] Technical Solution

[0012] In order to solve the above-mentioned problems, the speaker according to an embodiment of the present invention is characterized in that it includes: a box, which is configured in a rectangular shape; a speaker unit, which is installed on at least one side of the box; a partition, which is configured inside the box and divides the space, and the partition divides the space inside the box and prepares the space starting from the speaker unit into a space with an asymmetric cross-section having a tunnel structure.

[0013] Effects of the Invention

[0014] According to the present invention, the space along the direction of travel of sound waves in the internal space of the speaker has an asymmetric structure and an asymmetric cross-section. The asymmetric structure has a continuous dispersion effect on the sound pressure (sound waves) propagating in the sound wave travel space and the reflected sound pressure (sound waves). The dispersion effect of the sound pressure (sound waves) will further suppress excessive resonance of specific frequencies. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Below, in order to facilitate the implementation by ordinary technicians in the technical field to which the present invention belongs, embodiments of the present invention are described in detail with reference to the accompanying drawings. However, the present invention can be embodied in a variety of different forms and is not limited to the embodiments described herein. In the accompanying drawings, parts not related to the description are omitted in order to clearly illustrate the present invention, and similar parts in the entire specification are marked with similar reference numerals.

[0053] Throughout the specification, when it is mentioned that a part “includes” a certain constituent element, unless there is no particular description to the contrary, it means that other constituent elements may be included rather than excluding other constituent elements.

[0054] Hereinafter, a speaker according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0055] The speaker according to the present invention includes: a box body, which is configured in a hexahedral shape; a speaker unit, which is installed on at least one side of the box body; and a partition, which is configured inside the box body and divides the space. The partition divides the space inside the box body, and the space starting from the speaker unit is a space with an asymmetric cross-section having a tunnel structure, and the asymmetric cross-sectional structure is continuously maintained. The space inside the speaker according to the present invention is continuously configured as an asymmetric cross-sectional structure. In the embodiment of the present invention, a situation in which the cross-sectional area gradually decreases is exemplified, but it is not limited to this. It can also be configured in a manner in which the cross-sectional area increases, or it can also be configured in a manner in which the cross-sectional area increases and then decreases, or it can be configured in a manner in which the cross-sectional area decreases and then increases.

[0056] The box is exemplified as having a long length along the vertical direction, but can also be configured as a long shape along the horizontal direction, or configured as a cube, a rectangular parallelepiped, or one side of the box is inclined. When the box is configured as a rectangular parallelepiped, the six faces are called the upper surface, the lower surface, the front surface, the back surface, the left side face, and the right side face.

[0057] The speaker unit can be arranged on any one of the upper surface, front surface, back surface, and left side surface, and there are many options for configuration depending on the indoor space form where the speaker will be installed and the structure of the space where the speaker is arranged.

[0130] The cross-sectional area gradually decreases along the direction of the sound wave propagation starting from the speaker unit 21, and each channel is formed asymmetrically.

[0131] Referring to Fig.15a and Fig.15b , for the partition xx, the bent partitions in a shape extend on one side of the box, and the bent partitions with gradually increasing bending angles are connected to each other. Therefore, the bent partition xx is arranged in a spiral shape towards the center of the box.

[0132] Referring to Fig.15b , the speaker unit 21 is arranged at the center of the front face part 13, and the front face part can be arranged in a square shape. The cross-sectional area of the sound waves starting from the speaker unit 21 gradually decreases and passes through the tunnel - type channels formed asymmetrically.

[0133] According to the present invention, the space in the direction of sound wave propagation toward the internal space of the speaker has an asymmetric structure and an asymmetric cross-section. The asymmetric structure has a continuous dispersion effect on the sound pressure (sound wave) propagating in the sound wave propagation space and the reflected sound pressure (sound wave). The dispersion effect of the sound pressure (sound wave) will further suppress excessive resonance of specific frequencies.

[0134] The above description of the present invention is for illustration, and those skilled in the art to which the present invention belongs can understand that it can be easily transformed into other specific forms without changing the technical ideas or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all aspects, rather than restrictive. For example, each component described as a single type can be implemented in a dispersed manner, and similarly, the components described as forming a dispersed form can also be implemented in a combined form.

[0135] Compared with the above detailed description, the scope of the present invention is reflected by the following patent claims, and all changes or modifications derived from the meaning and scope of the patent claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
