Description

Technical Field

[0001] This utility model relates to the technical field of microphone mounting and adjustment devices, and in particular to a microphone mounting and adjustment device. Background Technology

[0002] The core purpose of installing pickups on guitars is to break through the physical limitations of acoustic instruments, giving the player absolute control over the sound. Whether it's an acoustic or electric guitar, the pickup is not just an "amplifier," but also a brush for creating tone, allowing the guitar to adapt to all needs, from bedroom practice to a stage in front of thousands, becoming an indispensable instrument in modern music. In the process of installing pickups on existing acoustic guitars, to reduce the number of holes, most pickups are installed at the soundhole position on the guitar's top. After installation, the vertical distance between the pickup and the strings is fixed. However, the vertical distance between the pickup body and the strings has a significant impact on the performance during playing. If the pickup is too high (closer to the strings), the output signal will be amplified: the string vibrations are closer to the pickup core, the induced magnetic field changes more drastically, resulting in a larger output volume. High frequencies are emphasized: when the pickup is too close to the strings, it captures more of the string's high-frequency vibrations (such as harmonics), making the tone sharper, brighter, and even with a "cold metallic" feel. Magnetic pull effect: A strong magnetic field may exert a slight resistance (magnetic pull) on the strings, affecting their natural vibration and causing tone distortion or dynamic compression. A lower pickup position results in a weaker output signal: if the strings are too far from the pickup, the sensed magnetic field change is weakened, reducing volume and potentially requiring increased amplifier gain compensation. Low-frequency enhancement: When the pickup is further from the strings, it is more sensitive to low-frequency vibrations (such as the fundamental frequency), resulting in a warmer, fuller tone, but potentially lacking clarity. Dynamic loss: When the string vibration amplitude is large (such as with a power chord), the pickup may not be able to fully capture the dynamic range, causing the sound to be "compressed" or "muffled." Therefore, the distance between the pickup and the strings affects the guitar's tone. Since acoustic guitars often have pickups added later without distance adjustment, a pickup mounting and adjustment mechanism is needed to address these issues. Utility Model Content

[0003] This utility model provides a pickup installation and adjustment device, which improves the existing pickup structure so that after being installed at the tone hole, it can adjust the distance between itself and the strings, thereby achieving the effect of changing the timbre.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0024] To enable those skilled in the art to understand the specific details of pickup installation on existing acoustic guitars, first refer to... Figure 1 and Figure 2 As an acoustic instrument, the acoustic guitar 1 generally does not have a pickup. However, in order to overcome the physical limitations of acoustic instruments and achieve sound amplification, enhancement, and diversified applications, some acoustic guitar 1 owners choose to add a pickup later. The pickup is usually installed on the sound hole 2 of the acoustic guitar 1. The pickup body 3 is installed by clamping the two sides of the pickup body 3 to the side wall forming the sound hole 2. The pickup body 3 is connected to the connector 301 on the side wall of the guitar 1 through a wire (not shown in the figure). After connecting the external amplifier cable to the connector 301, the sound can be amplified.

[0025] refer to Figure 3 and Figure 4The existing microphone body 3 has extension plates 4 on both sides, and a clamping plate 5 below the extension plates 4. A guide rod is fixedly connected to the extension plates 4, and the guide rod slides through the extension plates 4. A protruding head is located at the bottom of the extension plates 4, and the diameter of the protruding head is larger than the diameter of other parts of the guide rod to prevent the clamping plate 5 from detaching. A second lead screw 7 is also provided on the extension plates 4, and the second lead screw 7 is rotatably connected to the extension plates 4. The threaded portion 14 of the second lead screw 7 is threadedly connected to the clamping plate 5 below the extension plates 4. Therefore, in use, by rotating the second lead screw 7, the clamping plate 5 can be moved along the direction of the guide rod under the drive of the threaded portion 14. When the pickup body 3 is moved towards the extension plate 4 and away from the extension plate 4 to install the pickup body 3 on the sound hole 2 of the guitar 1, it is achieved by clamping the side wall forming the sound hole 2 between the extension plate 4 and the clamp plate 5. The problem with the existing technology is that after the pickup body 3 is installed on the guitar 1, the vertical distance between its upper surface and the strings is fixed and cannot be adjusted. The distance between the upper surface of the pickup and the strings significantly affects the tone and dynamic response of the guitar 1 (the appropriate height is usually about 2-4mm from the string to the top of the pickup magnet, which can balance the soft plucking and the strong strumming of the strings, so that the tone transitions naturally from clean to distorted).

[0026] refer to Figures 5-10 This invention improves upon the existing pickup body 3, enabling it to be adjusted after installation to allow for appropriate adjustment of the distance between its upper surface and the strings. Specifically, this invention provides a pickup installation and adjustment device, including L-shaped plates 9 on both sides of the pickup body 3 and lugs 8 integrally formed with both sides of the pickup body 3. A groove 10 adapted to the lug 8 is provided on the vertical arm of the L-shaped plate 9 near the side of the lug 8. A first lead screw 11 is rotatably connected to the horizontal arm of the L-shaped plate 9. The threaded portion 14 of the first lead screw 11 is threadedly engaged with the lug 8 inside the groove 10. Rotating the first lead screw 11 causes the lug 8 to move the pickup body 3 up and down along the groove 10. A movable clamping plate 5 is located below the L-shaped plate, and a guide tube passing through the movable clamping plate 5 is fixed at the bottom of the horizontal arm. The column 6 and the horizontal arm are rotatably connected to a second lead screw 7. The threaded part 14 of the second lead screw 7 is threadedly engaged with the movable clamping plate 5. As can be seen from the above, the improvement made by it compared with the prior art is that the part clamped on the side wall forming the sound hole 2 can be adjusted up and down. The similarity with the prior art is that the side wall can be clamped by the cooperation between the horizontal arm of the L-shaped plate 9 and the clamping plate 5, so as to realize the installation of the pickup body 3. That is, by rotating the second lead screw 7, the distance between the L-shaped plate 9 and the clamping plate 5 can be adjusted, so as to install the pickup body 3 in the sound hole 2. Then, by rotating the first lead screw 11, the pickup body 3 can move up and down relative to the vertical arm of the L-shaped plate 9, so as to adjust the vertical distance of the pickup body 3 relative to the string.

[0027] Since the height of both sides of the pickup body 3 needs to be adjusted by rotating the first lead screw 11, in order to avoid the first lead screw 11 on the other side obstructing the adjustment when rotating the first lead screw 11 on one side, a ball 802 with an internal thread in the center is provided at the threaded engagement position between the lug 8 and the first lead screw 11. The ball 802 is located inside the spherical cavity 801 of the lug 8. When the first lead screw 11 on one side is rotated, the body of the pickup on that side rises. Since the first lead screw 11 on the other side is not rotated, the pickup body 3 on the other side remains at its original height. The height difference between the two sides of the pickup body 3 can be compensated by rotating the lug 8 relative to the ball 802 at a certain angle. Thus, the design of the ball 802 not only enables the two sides of the pickup body 3 to be adjusted to different heights, but also avoids the first lead screw 11 on the other side obstructing the raising of the pickup body 3 when only one side of the first lead screw 11 is rotated.

[0028] Furthermore, the convex lugs 8 are integrally molded on both sides of the pickup body 3 near the bottom, which can maximize the proximity of the pickup body 3 to the strings. During adjustment, the pickup body 3 can be gradually adjusted downwards from its highest position. After adjusting to a certain position, pluck the strings to test the sound, and then adjust again until the most suitable state is reached.

[0029] It should be further explained that both the first lead screw 11 and the second lead screw 7 include an adjusting head (with a cross groove or a slotted groove) integrally formed with the adjusting head, a journal 13 integrally formed with the adjusting head, and a threaded portion 14 integrally formed with the journal 13. The journal 13 is a smooth rod-shaped body, and the upper and lower positions of the journal 13 are respectively provided with flanges 12. The length of the journal 13 of the first lead screw 11 corresponds to the thickness of the upper sidewall of the slide groove 10, thereby enabling the first lead screw 11 to rotate only relative to the upper sidewall of the slide groove 10. Similarly, the length of the journal 13 of the second lead screw 7 is also equal to the thickness of the horizontal arm. Under the action of the two flanges 12, it is ensured that the second lead screw 7 cannot move up and down relative to the horizontal arm, but can only perform relative rotational movement.

Those skilled in the art should understand that this utility model is not limited to the above-described embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
