Abstract
Description
Technical Field
[0001] This utility model relates to the field of loudspeaker technology, and in particular to a tooling for testing the sound of a miniature loudspeaker. Background Technology
[0002] A miniature loudspeaker is a small electronic component that converts electrical signals into sound signals through electro-acoustic conversion. Its core structure includes a magnetic circuit system, a vibrating component, and an acoustic cavity. It utilizes an electric current to drive a voice coil to vibrate in a magnetic field, which in turn drives a diaphragm to push air and generate sound waves, thus achieving electro-acoustic energy conversion.
[0003] Before leaving the factory, miniature loudspeakers need to undergo an audio test to check if they can produce sound normally. Current audio testing devices are only compatible with one model of miniature loudspeaker; when the structure of the miniature loudspeaker changes, the current audio testing devices cannot effectively detect it.
[0004] Therefore, there is a need to provide a miniature loudspeaker listening test fixture in order to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a miniature loudspeaker listening test fixture that is compatible with miniature loudspeakers of different structures and can effectively test their listening performance.
[0006] To achieve the above-mentioned objectives, a miniature loudspeaker listening test fixture is provided, comprising a support mechanism and a clamping mechanism;
[0007] The support mechanism includes a workbench and a positioning plate;
[0008] The upper surface of the workbench has a mounting groove, and a sound outlet is located at the center of the bottom of the mounting groove;
[0009] The positioning plate is disposed in the mounting groove and fits against the bottom of the mounting groove;
[0010] The positioning plate is provided with a contoured through hole, which is located directly above the sound outlet hole;
[0011] The clamping mechanism includes a housing, several clamping rods, and two conductive pins;
[0012] The housing is hinged to the workbench;
[0013] Several of the clamping rods are inserted into the housing, and the clamping rods extend out of the bottom of the housing;
[0014] Two conductive pins are inserted into the housing and extend out of the bottom of the housing. When the housing is closed on the worktable, the two conductive pins make contact with the positive and negative terminals of the placed miniature speaker, respectively.
[0015] The tops of the two conductive pins are connected to an external control system via wires.
[0016] Preferably, the side of the housing has a groove, and the upper parts of the two conductive pins are located in the groove.
[0017] Preferably, the worktable has a foam frame at the edge of the mounting groove, and the bottom of the housing has a protrusion that is adapted to the mounting groove.
[0018] Furthermore, the bottom of the mounting groove has a layer of foam, and the foam layer has clearance holes at the position corresponding to the sound outlet hole.
[0019] Preferably, a protective cover is fixed to the top of the housing by bolts.
[0020] Preferably, the clamping rod is an elastic telescopic rod.
[0021] The advantages of this miniature loudspeaker sound detection fixture compared to existing technologies are as follows:
[0022] (1) By replacing different positioning plates, miniature speakers with different structures can be adapted and effectively tested for sound.
[0023] (2) The workbench has a foam frame at the edge of the mounting groove, and the bottom of the housing has a protrusion that matches the mounting groove; the bottom of the mounting groove has a foam layer, and the foam layer has a clearance hole at the position of the sound outlet; during the testing of the miniature loudspeaker, the entire fixture is effectively sealed to avoid sound leakage and ensure the accuracy of the test.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] Example
[0034] like Figure 1 As shown in the figure, a miniature loudspeaker listening test fixture of this embodiment includes a support mechanism and a clamping mechanism.
[0035] like Figure 4 As shown, the support mechanism includes a worktable 1 and a positioning plate 2; Figure 2 As shown, the upper surface of the workbench 1 has a mounting groove 3, and the bottom center of the mounting groove 3 has a sound outlet 4; the positioning plate 2 is disposed within the mounting groove 3 and fits against the bottom of the mounting groove 3; as shown Figure 3 As shown, the positioning plate 2 is provided with a contoured through hole 5, which is located directly above the sound outlet hole 4.
[0036] The clamping mechanism includes a housing 6, a plurality of clamping rods 7 and two conductive pins 8; the housing 6 is hinged to the worktable 1; the plurality of clamping rods 7 are inserted into the housing 6 and extend out of the bottom of the housing 6.
[0037] like Figure 6 As shown, two conductive pins 8 are inserted into the housing 6 and extend out of the bottom of the housing 6; when the housing 6 is closed on the worktable 1, the two conductive pins 8 are in contact with the positive and negative terminals of the placed miniature speaker respectively; the tops of the two conductive pins 8 are connected to the external control system through wires.
[0038] In this embodiment, the side of the housing 6 has a groove 9, and the upper part of the two conductive pins 8 is located in the groove 9. This arrangement makes it convenient for the operator to connect the wire connector on the controller to the two conductive pins 8 from the side, without affecting the housing covering the mounting groove on the worktable.
[0039] In this embodiment, as Figure 4 As shown, the workbench 1 has a foam frame 10 located at the edge of the mounting groove 3, such as... Figure 7As shown, the bottom of the housing 6 has a protrusion 11, which is adapted to the mounting groove 3; this arrangement effectively seals the housing 6 after it covers the mounting groove 3 on the worktable 1, ensuring the accuracy of the listening test of the miniature speaker.
[0040] Furthermore, in this embodiment, as Figure 4 As shown, the bottom of the mounting groove 3 has a layer of foam 12, and the foam layer 12 has a clearance hole 13 at the position corresponding to the sound hole 4; furthermore, it plays a sealing role to ensure the accuracy of the sound detection of the miniature loudspeaker.
[0041] In this embodiment, as Figure 5 As shown, the top of the housing 6 is fixed with a protective cover 14 by bolts, so that the operator will not accidentally touch the wire connected to the conductive pin when opening and closing the housing 6.
[0042] In this embodiment, the clamping rod 7 is an elastic telescopic rod, which effectively avoids crushing the miniature speaker to be tested.
[0043] When the above-mentioned miniature loudspeaker listening test fixture is in operation, first select a suitable positioning plate 2 and place it on the mounting groove 3, place the miniature loudspeaker on the contoured through hole 5 and support it with the support beam on the sound outlet hole 4, with the sound output area of the miniature loudspeaker facing the sound outlet hole 4, rotate the housing 6 so that the clamping rod 7 presses down on the miniature loudspeaker, and the two conductive pins 8 contact the positive and negative terminals of the miniature loudspeaker to achieve conductivity, and then listen to it.
