Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1-Figure 4 As shown, the test fixture of the double-sided sound-producing speaker provided in this embodiment includes a detachably connected front test component 10 and a rear test component 20, wherein the front test component 10 includes two relatively arranged test modules 10a, and the two test modules 10a are separable, and the speaker 100 is fixed between the two test modules 10a, and the rear test component 20 covers one side of the speaker 100, and the speaker 100 is confined within a sealed cavity formed by the front test component 10 and the rear test component 20.

[0026] Combination Figure 5-Figure 6 As shown, specifically, the test module 10a includes a first base 11, and a mounting groove 12 is provided at one end of the first base 11. The mounting grooves 12 in the two test modules 10a correspond to each other, and the mounting grooves 12 are used to accommodate speakers. A plurality of first magnetic components 13 are provided at one end of the first base 11, and the first magnetic components 13 are located outside the mounting groove 12. The two test modules 10a are adsorbed and connected by the first magnetic components 13, and the first magnetic components 13 can be made of magnetic steel.

[0027] Thus, after the two test modules 10 a are adsorbed and fastened together by the first magnetic element 13 , the speaker to be tested can be fixed in the test cavity formed by the mounting groove 12 .

[0028] Furthermore, a first sealing ring 14 is bonded to the outer side of the installation groove 12. The first sealing ring 14 is made of foam material, which plays a sealing role and can adapt to changes in the height tolerance range of the speaker to ensure the sealing effect.

[0029] Furthermore, a plurality of test holes 16 for laser amplitude testing are arranged in the mounting groove 12 , and high-transmittance optical glass 17 is attached to the test holes 16 , which not only meets the amplitude testing requirements but also ensures that the front cavity is airtight.

[0030] Furthermore, a plurality of second magnetic members 15 are disposed on the side of the first base 11 . The second magnetic members 15 are disposed in two rows to ensure the adsorption effect. The second magnetic members 15 can also be made of magnetic steel.

[0031] The post-test assembly 20 includes a second base 21 , a side surface of the second base 21 is provided with a plurality of third magnetic members 22 , and the second magnetic members 15 are adsorbed and matched with the third magnetic members 22 .

[0032] Furthermore, a receiving groove 23 is disposed on one side surface of the second base 21 , and a second sealing ring 24 is disposed around the outer side of the receiving groove 23 , and the second sealing ring 24 contacts and cooperates with the front test assembly 10 .

[0033] Furthermore, two mounting posts 25 are disposed in the receiving groove 23 , and electrically connected wires 26 and probes 27 are disposed on the mounting posts 25 . The wires 26 extend to the outside of the second base 21 , and the probes 27 extend to the receiving groove 23 and contact and cooperate with the speaker.

[0034] Furthermore, a pressure relief hole is provided in the accommodating groove 23, and a damper 28 is provided in the pressure relief hole.

[0035] Therefore, after the front test component 10 is assembled and the speaker is fixed inside, part of the speaker is exposed on one side of the front test component, and the rear test component 20 is adsorbed on the side of the front test component 10 to complete the assembly. The position of the accommodating groove 23 completely covers the speaker, and cooperates with the front test component 10 to form a sealed test cavity. The test signal is transmitted to the conductive spring probe 27 through four wires 26, and the conductive spring probe 27 elastically contacts the speaker signal input PAD point to stimulate the speaker to work and perform the test.
