Detailed Implementation

[0013] Example 1 like Figures 1 to 3As shown, a height-adjustable microphone includes a support base 1, a metal-shaped flexible tube 2, a support seat 3, a hinge seat 4, and a microphone body 5. The two ends of the metal-shaped flexible tube 2 are connected to the support base 1 and the support seat 3, respectively. One end of the hinge seat 4 is fixed with a hinge ball 6. The top of the support seat 3 has a spherical groove 7, and the hinge ball 6 is movably fitted into the spherical groove 7. The microphone body 5 is installed at the end of the hinge seat 4 away from the support seat 3. The metal-shaped flexible tube 2 can be bent, stretched, and shaped arbitrarily, allowing adjustment of the height and angle of the microphone body 5 to adapt to different sitting postures and the sitting height of different teachers, thus broadening its application range. The hinge seat 4 can flexibly deflect on the support seat 3 to precisely adjust the angle of the microphone body 5, enabling the microphone body to be accurately aligned with the sound source. This solves the problems of rigid angle adjustment and easy displacement due to touch in traditional microphones, effectively improving the stability of sound reception.

[0014] Example 2 Based on Example 1, such as Figure 1 and Figure 2 As shown, the support base 3 includes a first base body 14 and a second base body 15. The first base body 14 is connected to a metal shaping hose 2. A hemispherical groove 16 is provided at the end of the first base body 14 away from the metal shaping hose 2. An arc-shaped through hole 17 is provided on the second base body 15. The second base body 15 is detachably connected to the first base body 14 so that the hemispherical groove 16 and the arc-shaped through hole 17 form a spherical groove 7. The first base body 14 and the second base body 15 adopt a split structure to facilitate the installation of the hinge ball 6. During installation, the first base body 14 and the second base body 15 are separated, the hinge ball 6 is placed into the hemispherical groove 16, and then the second base body 15 is installed on the first base body 14. At this time, the arc-shaped through hole 17 and the hemispherical groove 16 combine to form a spherical groove 7, and the hinge ball 6 extends partially from the arc-shaped through hole 17 to complete the spherical hinge installation. This detachable method facilitates the replacement of the microphone body 5, so that the microphone body 5 does not need to be replaced as a whole after damage, thus reducing costs.
