Resonance improvement device attached to the resonance part

[0001] The present invention relates to a resonance improvement device attached to a resonance unit, and a resonance improvement device including a magnetic part and a coil part is attached to a musical instrument and speaker having a resonance unit such as a soundboard or a resonance box, so that vibration transmitted from the resonance unit is transmitted to the magnetic part and the coil part of the resonance improvement device, and the resonance improvement device resonates, thereby making the sound resonating from the resonance unit and the resonance improvement device bright, thick, powerful, and long.

[0002] Generally, string instruments are divided into percussion instruments such as the piano, plucked instruments such as the guitar, and bowed string instruments such as the violin. All of these instruments produce a desired sound by striking, plucking, or twisting the strings of the string instrument. They can be divided into a fixed part that fixes one side of the string, a tuning part that fixes and tunes the other side of the string, and a resonating part that produces sound between the fixed part and the tuning part.

[0003] Among them, in the case of the piano, which is a stringed instrument, the sound is expressed evenly from low to high notes, clear and bright without any cloudy or tinkling sounds. This sound expression is achieved when the keys are pressed, the hammer inside the piano strikes the lower strings, and the vibration of the strings is transmitted to the soundboard through the bridge that is attached to the soundboard and supports one end of the strings, and the soundboard vibrates the air, producing a loud sound.

[0004] Technologies are being developed to produce accurate and clear sounds from stringed instruments such as pianos and guitars. For example, Korean Patent Registration No. 302627 discloses a piano having a steel frame coupled to one side of a soundboard, a tuning pin rotatably coupled to the steel frame, and a plurality of strings arranged on the soundboard so that one end thereof is fixed to the tuning pin and the tension of which is adjusted according to the rotation of the tuning pin, characterized in that a plurality of slit grooves are formed longitudinally on a portion of the tuning pin, a screw hole is formed longitudinally inside the tuning pin, and an adjusting screw member is provided with a screw formed in an inclined portion so that the outer diameter of the portion of the tuning pin where the slit groove is formed becomes larger as it enters the screw hole. According to this configuration, since the tension of the string can be finely adjusted and tuned without rotating the tuning pin, wear of the screw part formed in the steel frame and the tuning force can be reduced, thereby extending the lifespan and simplifying the tuning operation. The "tuning device" is posted.

[0005] In addition, Republic of Korea Registration No. 1502242 discloses an improved "stringed instrument that generates high-quality sound and prevents damage" that is improved to prevent the sound generating unit from deterioration and deformation due to moisture in advance, thereby improving durability, shock resistance, and enabling the implementation of high-quality sound, and to ensure that the vibration of the strings in the sound generating unit is not transmitted to the string control unit, thereby enabling the implementation of high-quality sound, while allowing the head of the string control unit to be in a horizontal state with the string generating unit without having to bend it backwards, thereby facilitating storage and preventing the head from being damaged as much as possible, thereby promoting an increase in lifespan.

[0006] However, in the aforementioned Korean Patent Registration No. 302627, the "piano tuning device" has a large outer diameter of a plurality of slit grooves formed longitudinally on a portion of the tuning pins through an adjusting screw member, thereby enabling fine adjustment of the tension of the strings without rotating the tuning pins. However, since it does not produce good overtones, there is a problem that it is not easy to play smoothly without a break between notes, such as legato, as with conventional pianos.

[0007] In addition, in the "stringed instrument for producing high-quality sound and preventing damage" of Republic of Korea Registration No. 1502242, a waterproof plate member attached and fixed to the upper surface of a neck member, a fingerboard decorative member fixed to the upper portion of the waterproof plate member and having a plurality of through-holes for strings, and a string support means including a plurality of strings having fixing projections that penetrate the through-holes for strings and are fixed to the upper surface of the waterproof plate member, and a vibration blocking means integrally provided at the tip of the waterproof plate member so that a plurality of strings pass through it in a U shape and are supported to be bent in the longitudinal direction, thereby blocking the transmission of the vibration of the strings to the string control unit, and the head of the string control unit is configured to be horizontal with the neck member, thereby producing high-quality sound and preventing damage, but the configuration is not simple, and there was a problem that it was difficult to directly apply it to conventional stringed instruments.

[0008] Therefore, in order to solve the above-mentioned problem, a resonance improvement device including a magnetic part composed of a permanent magnet and a ferromagnetic coil part having a compression spring or tensile spring structure is configured, and the magnetic part is attached to a ferromagnetic part configured in a resonance part such as a soundboard or sound box of a musical instrument or speaker, and by attaching one side or the center of the coil part to the magnetic part, the vibration transmitted from the resonance part is transmitted to the ferromagnetic part, and the resonance improvement device attached magnetically to the vibrating ferromagnetic part resonates.

[0009] Alternatively, by fitting or hanging the ferromagnetic coil part of the resonance improvement device onto the resonance part of the musical instrument or speaker and fixing it, and attaching a magnetic part to the coil part, the vibration transmitted from the resonance part is transmitted to the coil part and the magnetic part, thereby causing the resonance improvement device to resonate.

[0010] In this way, the present invention has the effect of simply attaching the magnetic part of the resonance improvement device to various ferromagnetic parts such as screws, frames, and bridges formed in the resonance part of a typical musical instrument and speaker, such as iron plates, and simply fitting or hanging the coil part on the resonance part to fix it, so that the vibration of the resonance part is transmitted to the resonance improvement device through the magnetic part and the coil part, and the resonance improvement device resonates, thereby improving the overtones, and thereby expressing the sound bright, thick, powerful, and long, and making it easy to play legato in which the sounds are naturally connected.

[0020] The present invention is a resonance improvement device attached to a resonance unit, and is composed of a magnetic part and a coil part. The magnetic part of the resonance improvement device is used by simply attaching it to a ferromagnetic part such as a screw or iron plate of a musical instrument or speaker in which the resonance unit is formed, or the coil part is used by fitting or hanging it on the resonance unit of the musical instrument or speaker and fixing it. The configuration and method of use of this resonance improvement device are described in detail as follows.

[0021]

[0022] First, the sound improvement device (100) is composed of a magnetic part (110) and a coil part, and the magnetic part (110) is composed of a permanent magnet.

[0023] At this time, it is preferable that the magnetic part (110) be composed of neodymium having a width, length, thickness, and diameter of 2 to 10 mm.

[0024] And the coil part is a compression spring or tension spring structure made of a ferromagnetic material, and is classified into a vibration coil (121), a bridge coil (122), and a resonance coil (123) depending on the use.

[0025] Among them, the bridge coil (122) is the longest coil part as it connects the string (211) of the instrument and the magnetic part (110), the length and diameter of the resonance coil (123) vary depending on how it is fixed to the instrument and speaker, and the vibration coil (121) may be the shortest coil part.

[0026]

[0027] The sound improvement device (100) configured in this way is divided into a method of attaching the magnetic part (110) to a sounding part (210) such as a soundboard of a piano (201), a sound box of a musical instrument, or a sound box of a speaker, and a method of fixing a sounding coil (123). In the case of attaching the magnetic part (110), the magnetic part (110) of the sound improvement device (100) is attached to a ferromagnetic component such as a frame (221), a screw (222), or a bridge among the sounding parts (210).

[0028] For example, as illustrated in Fig. 1, a magnetic part (110) is attached to a frame (221) of a piano (201). In this case, even if only the magnetic part (110) is attached, the vibration transmitted from the resonance part (210) is transmitted to the frame (221), which is a ferromagnetic component, and the magnetic part (110) of the resonance improvement device (100) attached to the vibrating frame (221) resonates, thereby improving the overall resonance.

[0029] This means that the vibration generated from the string (211) of the piano (201) is transmitted to the frame (221), and the vibration is also transmitted to the magnetic part (110) through the frame (221). However, the magnetic part (110) that is not fixed to the frame (221) but attached by magnetic force is slightly separated from the frame (221) by the vibration, and the gap is strongly attached by the magnetic force of the magnetic part (110), and is again widened by the vibration, but is strongly attached again by the magnetic force, thereby resonating.

[0030] Here, if there is no ferromagnetic component of the resonating portion (210) at the location where the magnetic portion (110) is to be attached, a ferromagnetic body such as a screw (222) or an iron plate may be fixed to the resonating portion (210) and then the magnetic portion (110) may be attached.

[0031] And, by attaching a coil part to the magnetic part (110) of the resonance improvement device (100) attached to the ferromagnetic part of the resonance part (210), the overtones can be further improved. In the case of the vibration coil (121), as shown in FIG. 2, by attaching one end or the center of the vibration coil (121) to the magnetic part (110), the vibration coil (121) functions as a small resonance chamber, so that the other end or both ends of the vibration coil (121) that is not attached to the magnetic part (110) in the vibration coil (121) vibrate and resonate to improve the overall resonance.

[0032] In addition, as illustrated in FIG. 3, a magnetic part (110) is attached to a screw (222) fastened to a resonance part (210) of a piano (201), and a vibration coil (121) is placed on the screw (222). By attaching one end of the inner side of the vibration coil (121) to the magnetic part (110), the vibration coil (121) placed on the screw (222) is fixed by the magnetic force of the magnetic part (110), so that the vibration coil (121) functions as a small resonance chamber to improve resonance.

[0033] And in the case of the bridge coil (122), it is used in a piano (201) and a stringed instrument. As shown in FIG. 4, one side of the bridge coil (122) is inserted into the string (221) between the agraph (223) and the tuning pin (224) of the piano (201), and as shown in FIG. 5, the other side of the bridge coil (122) is attached to the magnetic part (110) attached to the screw (222) of the piano (201), so that the string (211) between the agraph (223) and the tuning pin (224) and the magnetic part (110) are connected by the bridge coil (122), so that vibrations are transmitted to each other, thereby improving the overall resonance.

[0034]

[0035] Next, when fixing the resonance coil (123) to the resonance part (210) of the musical instrument and speaker, the resonance coil (123) is fixed by inserting or hanging it, and as shown in FIGS. 6 to 8, the resonance coil (123) is placed on the tuning pin (224) of the piano (201) and guitar (202), and the string (211) fixed to the tuning pin (224) is inserted into the gap of the resonance coil (123) to fix it, thereby providing the function of a small resonance box added to the resonance part (210).

[0036] In addition, as shown in FIGS. 9 and 10, the two ends of the resonance coil (123) can be fixed by hanging them on both sides of the aperture and string frame of the cello (203), and one end of the resonance coil (123) can be fixed by screwing it into the resonance part (210) of the instrument or speaker, or the resonance coil (123) can be fastened to one side of the bow of the cello (203) or violin.

[0037] And, by attaching a magnetic part (110) to the resonance coil (123) fixed to the resonance part (210), the overtones can be further improved. In the case of a portable musical instrument, as shown in FIGS. 7 and 8, it is preferable to attach the magnetic part (110) inside the resonance coil (123) to prevent the magnetic part (110) from coming off.

[0038]

[0039] In addition, the resonance improvement device (100) can also be applied to the resonance part (210) of a wind instrument or percussion instrument, and when using a resonance coil (123) in a wind instrument, the coil structure can be configured in a circular shape, and the circular resonance coil (123) can be used by fitting it into the resonance part (210) of the wind instrument.

[0040]

[0041] In this way, the present invention has the feature that by simply attaching the magnetic part (110) of the resonance improvement device (100) to various ferromagnetic parts such as iron plates, such as screws (222), frames (221), and bridges formed in the resonance part (210) of a typical musical instrument and speaker, and simply fitting or hanging the coil part on the resonance part (210) and fixing it, the vibration of the resonance part (210) is transmitted to the resonance improvement device (100) through the magnetic part (110) and the coil part, so that the resonance improvement device (100) resonates, thereby improving the overtones, and thereby expressing the sound brightly, thickly, powerfully, and long, and making it easy to play legato in which the sounds are naturally connected.
