[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-5As shown, this utility model provides a portable acoustic testing instrument for music teaching, including an acoustic testing instrument 1. A housing assembly 3 is provided on the surface of the acoustic testing instrument 1. A clamping mechanism 2 is provided on the surface of the housing assembly 3. The clamping mechanism 2 includes a threaded post 205, which is threadedly connected to the bottom end of the housing assembly 3. A U-shaped frame 201 is fixedly connected to the surface of the threaded post 205. An anti-slip block 203 is fixedly connected to the bottom end of the U-shaped frame 201. Guide blocks 202 are fixedly connected to the surface of the U-shaped frame 201 in two sets, symmetrically distributed on the surface of the U-shaped frame 201. A clamping plate 204 is slidably connected to the surface of the guide blocks 202. A movable post 206 is fixedly connected to the surface of the clamping plate 204, movably connected to the surface of the U-shaped frame 201. Multiple sets of slots 210 are provided on the surface of the movable post 206, evenly distributed on the movable post 201. On the surface of 06, a lower pressure block 207 is fixedly connected to the top of the movable column 206, and a first spring 208 is fixedly connected to the bottom of the lower pressure block 207. The first spring 208 is sleeved on the surface of the movable column 206, and the bottom of the first spring 208 is fixedly connected to the surface of the U-shaped frame 201. The clamping mechanism 2 also includes a slide rail 213, which is fixedly connected to the inside of the U-shaped frame 201. A slide plate 211 is movably connected to the surface of the U-shaped frame 201. A locking block 212 is fixedly connected to one end of the slide plate 211, and the locking block 212 is adapted to the locking groove 210. A connecting seat 216 is fixedly connected to the surface of the slide plate 211, and a lever 209 is fixedly connected to the top of the connecting seat 216. The lever 209 is movably connected to the surface of the U-shaped frame 201. A second spring 215 is fixedly connected to the surface of the connecting seat 216, and a vertical plate 214 is fixedly connected to one end of the second spring 215. The vertical plate 214 is fixedly connected to the inside of the U-shaped frame 201.

[0026] In this embodiment, by connecting the threaded post 205 to the housing assembly 3, during use, the gap of the U-shaped frame 201 can be aligned with the edge of the table, and the pressing block 207 can be pressed down, causing the movable post 206 to push the clamping plate 204 to slide on the surface of the guide block 202. At this time, the first spring 208 is compressed. Simultaneously, when the movable post 206 moves downward, the inclined surface at the upper end of the slot 210 contacts the inclined surface of the locking block 212, causing the slide plate 211 to slide on the surface of the slide rail 213. When the clamping plate 204 and the U-shaped frame 201 are clamped together at the edge of the table, the locking block 212 engages with the vertical surface at the lower end of the slot 210. When it is necessary to release... When the lever 209 is turned, the connecting seat 216 and the upright plate 214 cooperate to compress the second spring 215. At the same time, the slide plate 211 slides on the surface of the slide rail 213, causing the locking block 212 to disengage from the slot 210. The first spring 208 rebounds and drives the movable column 206 to move upward, causing the clamping plate 204 to loosen from the edge of the table. At the same time, the device can be placed directly on the table. The U-shaped frame 201 forms a base to stabilize the device. The anti-slip block 203 increases the friction and prevents the device from shifting. It can also be fixed to musical instruments, clothing, etc. through this mechanism, which greatly increases the scope of application and improves the adaptability of the device.

[0027] Example 2

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the housing assembly 3 includes a housing body 301, which is movably connected to the surface of the acoustic testing instrument 1. A fixing edge 303 is fixedly connected to the top of the housing body 301, a spherical protrusion 304 is fixedly connected to the inner side of the housing body 301, a heat dissipation mesh 305 is provided on the surface of the housing body 301, a groove 306 is provided on the surface of the housing body 301, and a boss 302 is fixedly connected to the surface of the housing body 301. The housing assembly 3 also includes a movable seat 307, which is fixedly connected to the bottom end of the housing body 301. A spherical movable block 308 is movably connected to the surface of the movable seat 307, and a connecting post 309 is fixedly connected to the surface of the spherical movable block 308. A threaded seat 310 is fixedly connected to one end of the connecting post 309, and the threaded seat 310 is threadedly connected to the surface of the threaded post 205.

[0029] In this embodiment, the acoustic tester 1 is placed inside the housing body 301, and the fixing edge 303 cooperates with the housing body 301 to fix the acoustic tester 1 inside. The housing body 301, the fixing edge 303, the spherical protrusions 304, and the grooves 306 are all made of rubber. The spherical protrusions 304 on both sides further fix the acoustic tester 1, and their elasticity can also protect the acoustic tester 1. The acoustic tester 1 is cooled by the heat dissipation mesh 305. At the same time, the grooves 306 are provided on the surface of the acoustic tester 1 so that the protrusions can protect the acoustic tester 1. The tester 1 is lifted up, which not only further dissipates heat but also increases the protection of its back. The protrusion 302 on the surface of the housing body 301 facilitates the disassembly of the housing body 301 and the acoustic tester 1, and can also be used as a hanging ring. The spherical movable block 308 at the bottom moves within the movable seat 307, allowing the angle to be freely adjusted during use. The device can be stably placed by connecting the threaded seat 310 on the surface of the connecting post 309 to the threaded post 205. It can also be connected to the triangular bracket through the threaded seat 310, which improves the adaptability of the device.

[0030] The working principle of this portable acoustic testing instrument for music teaching will be explained in detail below.

[0031] like Figure 1-5As shown, by connecting the threaded post 205 to the housing assembly 3, during use, the gap of the U-shaped frame 201 can be aligned with the edge of the table, and the pressing block 207 can be pressed down, causing the movable post 206 to push the clamping plate 204 to slide on the surface of the guide block 202. At this time, the first spring 208 is compressed. Simultaneously, when the movable post 206 moves downward, the inclined surface of the upper end of the slot 210 contacts the inclined surface of the block 212, causing the slide plate 211 to slide on the surface of the slide rail 213. When the clamping plate 204 and the U-shaped frame 201 are clamped together at the edge of the table, the vertical distance between the lower end of the block 212 and the slot 210 is reduced. The device is snap-fitted together. When it needs to be released, by moving the lever 209, the connecting seat 216 and the upright plate 214 engage to compress the second spring 215. At the same time, the sliding plate 211 slides on the surface of the slide rail 213, causing the locking block 212 to disengage from the locking slot 210. The first spring 208 rebounds, causing the movable column 206 to move upward, thus releasing the clamping plate 204 from the edge of the table. The device can then be placed directly on the tabletop. The U-shaped frame 201 forms a base to stabilize the device. The anti-slip block 203 increases friction to prevent displacement of the device. This mechanism can also be used to fix musical instruments, clothing, etc. This design greatly expands the applicability of the acoustic tester 1. The acoustic tester 1 is placed inside the housing body 301, and the fixing edge 303 cooperates with the housing body 301 to secure the acoustic tester 1. The housing body 301, fixing edge 303, spherical protrusions 304, and grooves 306 are all made of rubber. The spherical protrusions 304 on both sides further secure the acoustic tester 1, and their elasticity also protects the acoustic tester 1. Heat dissipation is achieved through the heat dissipation mesh 305, and grooves 306 are provided on the surface of the acoustic tester 1 to prevent heat from escaping from the protrusions. The acoustic tester 1 is lifted up, which not only further dissipates heat but also increases the protection of its back. The protrusion 302 on the surface of the housing body 301 facilitates the disassembly of the housing body 301 and the acoustic tester 1, and can also be used as a hanging ring. The spherical movable block 308 at the bottom moves within the movable seat 307, allowing the angle to be freely adjusted during use. The device can be stably placed by connecting the threaded seat 310 on the surface of the connecting post 309 to the threaded post 205. It can also be connected to the triangular bracket through the threaded seat 310, which improves the adaptability of the device.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
