[0036] Please refer to Figure 1 This embodiment discloses a speaker testing device, including a testing feeding mechanism 10 and a soundproof box 20, please refer to Figure 2 and Figure 3 The test mechanism includes an assembly plate 100, an upper template 200 and a lower template 300. The assembly plate 100 is installed with a baffle 110. Please refer to Figure 2 and Figure 4, a template recess 111 is provided on the first surface of the baffle 110, and a sound outlet 112 is provided in the template recess 111 and penetrates to the second surface of the baffle 110. After the assembly is completed, the assembly plate 100 is installed on the sound insulation box 20, and the second surface of the baffle 110 is located inside the sound insulation box 20. The upper template 200 is installed on the lifting and translation module 400, and the lifting and translation module 400 is used to realize lifting movement in the longitudinal direction and translation movement in the horizontal direction. In this way, the lifting and translation module 400 can drive the upper template 200 to realize movement in both longitudinal and horizontal directions. The lifting and translation module 400 is installed on the first surface of the assembly plate 100, and the lower template 300 is installed on the linear movement module 500, and moves linearly in the horizontal direction under the drive of the linear movement module 500. Please refer to Figure 5 and Figure 6 The lower template 300 is provided with a connected product accommodating recess 301 and a sound channel avoiding position 302, the sound channel avoiding position 302 faces the template recess 111, the shape and size of the product accommodating recess 301 are adapted to the speaker product to be tested, and by providing a position connected to the sound channel avoiding position 302, the sound outlet of the speaker product can be avoided so that the sound outlet of the speaker product faces the sound outlet 112 of the baffle 110, wherein the upper template 200 and the lower template 300 both have a first working position and a second working position, in the first working position, the upper template 200 and the lower template 300 are molded together and inserted into the template recess 111 and abut against the baffle 110, and in the second working position, the upper template 200 and the lower template 300 are separated from the template recess 111 and separated.

[0037] When the assembly is completed and the product is in use, the speaker product to be tested is placed on the product accommodating recess 301, and the linear moving module 500 drives the lower template 300 to move toward the baffle 110. During the movement, the upper template 200 is gradually lowered and moved toward the baffle 110 under the drive of the lifting and translational module 400 to achieve the mold closing of the upper template 200 and the lower template 300, and the speaker product placed in the product accommodating recess 301 is covered, and the template recess 111 is inserted and abutted against the baffle 110 to enclose the sound port of the speaker product and the sound outlet 112 on the baffle 110 in a relatively closed space, which is beneficial to improving the environmental anti-interference ability of the test, wherein the interior of the soundproof box 20 is a fully enclosed space, and a microphone 30 for collecting sound signals of the speaker product is installed in the soundproof box 20 and at a position adapted to the sound outlet 112 of the baffle 110.

[0038] There are many ways to realize the lifting and translational movement of the upper template 200, such as realizing the lifting movement by setting a lifting module, and realizing the translational movement by installing a translational module on the lifting module. Both the lifting module and the translational module can be driven by a motor or a cylinder. This implementation method requires synchronization of the movements of the lifting module, the translational module and the linear movement module 500, and has high requirements on the electrical control performance, so it needs to be optimized. To this end, this embodiment also provides another implementation method, for example:

[0039] Please refer to Figure 7 and Figure 8 The lifting and translation module 400 includes a bracket 410, a first slide rail 420, a lifting slider 430, a second slide rail 440 and a translation slider 450. The first slide rail 420 is installed on the bracket 410 and its length extends in the longitudinal direction. The lifting slider 430 is slidably installed on the first slide rail 420. The second slide rail 440 is installed on the lifting slider 430 and its length extends in the horizontal direction. The translation slider 450 is slidably installed on the second slide rail 440. The bracket 410 and the translation slider 450 are provided with a first guide portion 411 and a second guide portion 451 that are adapted thereto. The bracket 410 and the translation slider 450 are connected with an elastic reset member 460, such as a tension spring. The upper template 200 is installed on the translation slider 450. When in use, an external force is applied to the translation slider 450, so that the translation slider 450 moves along a predetermined trajectory with the cooperation of the first guide portion 411 and the second guide portion 451, wherein the cooperation of the first slide rail 420 and the lifting slider 430 provides a guide for the upper template 200 to slide up and down, and the cooperation of the second slide rail 440 and the translation slider 450 provides a guide for the upper template 200 to slide forward and backward. Through the guide for sliding up and down and the guide for sliding forward and backward, the upper template 200 can perform oblique movement within the longitudinal plane defined in the up and down and front and back directions, and power parts such as motors or cylinders can be omitted, which is beneficial to reducing energy consumption and reducing electrical control performance requirements.

[0040] Please refer to Figure 2 and Figure 5 The linear moving module 500 is provided with abutting members 510, which can abut against the side wall of the translation slider 450. The linear moving module 500 drives the abutting members 510 to abut against the side wall of the translation slider 450 during the movement, providing power for the movement of the translation slider 450. When the abutting members 510 move in the reverse direction, the force applied to the translation slider 450 is cancelled, and the translation slider 450 is reset under the action of the elastic reset member 460.

[0041] In order to reduce the friction between the abutment 510 and the translation slider 450, a rolling member 511, such as a roller or a ball, is provided at the end of the abutment 510. The rolling member 511 can convert the sliding friction into rolling friction, which is beneficial to reduce the wear between the abutment 510 and the translation slider 450, ensure that the upper template 200 is pushed into place, and thus improve the reliability of use.

[0042] Please refer to Figure 5 and Figure 7 A contact block 452 is installed on the side wall of the translation slider 450. The position of the contact block 452 is matched with the contact position of the abutment 510. The contact block 452 is installed at the force-bearing position of the translation slider 450. After long-term use, if the contact block 452 is severely worn, the contact block 452 can be replaced to ensure that the upper template 200 and the lower template 300 are in place, thereby improving the reliability of use.

[0043] The first guide portion 411 is a guide groove arranged on the bracket 410, and the second guide portion 451 is a guide wheel installed on the translation slider 450. The guide wheel is movably installed in the guide groove, and the guide wheel can move in the guide groove, so that the upper template 200 can be lifted and translated under the guiding action.

[0044] Please refer to Figure 5 , Figure 6 and Figure 8 , the upper template 200 and the lower template 300 are provided with matching first guide pillars 201 and first guide holes 303, and the lower template 300 and the assembly plate 100 are provided with matching second guide pillars 304 and second guide holes. When the mold is closed, the upper template 200 and the lower template 300 are guided by the cooperation of the first guide pillars 201 and the first guide holes 303 to calibrate the positions of the upper template 200 and the lower template 300. The first guide pillars 201 can be provided on the upper template 200 or the lower template 300, and similarly, the first guide holes 303 can be provided on the lower template 300 or the upper template 200. In the process of the lower template 300 moving toward the baffle 110 driven by the linear moving module 500, the positions of the lower template 300 and the baffle 110 are calibrated by the cooperation of the second guide pillars 304 and the second guide holes, so that the sound outlet of the speaker product is aligned with the sound outlet 112 on the baffle 110.

[0045] Please refer to Figure 5 In order to provide anti-interference capability, a first sealing ring 305 is provided at the connection between the upper template 200 and the lower template 300, so as to seal the contact position between the upper template 200 and the lower template 300 and reduce interference such as environmental temperature, humidity and noise.

[0046] Please refer to Figure 4A second sealing ring 114 is provided on the baffle 110 and adapted to the abutment position of the upper template 200 and the lower template 300. When testing, the upper template 200 and the lower template 300 respectively abut against the second sealing ring 114, thereby improving the sealing of the sound outlet position of the speaker product, which is beneficial to reducing the interference of environmental factors on the test.

[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
