DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0023] REFERENCE Figure 1 - Figure 3The utility model provides an embodiment: a microphone adjusting and fixing support for narrow space, including microphone body 1 and fixed frame 12, fixed frame 12 outer wall one side is provided with pneumatic cylinder 11, and pneumatic cylinder 11 output end is fixedly connected with installation support 10, and installation support 10 is provided with adjusting assembly inside, and this adjusting assembly is used for accurate adjustment microphone body 1's position, when needing to adjust the position of microphone as a whole, pneumatic cylinder 11 starts under the control of electromagnetic valve, when this passes through the telescopic action of pneumatic cylinder 11, can drive installation support 10 and the microphone fixing block 2 and microphone body 1 of installing on it whole shift, thereby make microphone will gradually approach product sound emitting mouth, through the accurate control of pneumatic cylinder 11, can ensure the distance between microphone and product sound emitting mouth is in the proper range, adjusting assembly includes X axis adjusting screw 9, and X axis adjusting screw 9 outer wall is connected in installation support 10 inside in screw thread, and X axis adjusting screw 9 outer wall one side is provided with X axis adjusting block 7, and X axis adjusting block 7 outer wall one side is fixedly connected with microphone fixing block 2, and microphone fixing block 2 is internally provided with placing groove 14, and placing groove 14 is used for placing microphone body 1, when needing to adjust microphone position in X axis direction, first loosens the X axis fixed screw 8 in installation support 10 inside, then can turn X axis adjusting screw 9, because X axis adjusting screw 9 is connected in installation support 10 inside in screw thread, so X axis adjusting screw 9 will move in installation support 10, thereby can drive X axis adjusting block 7 move in X axis direction, when X axis adjusting block 7 moves, will make microphone fixing block 2 and its inside fixed microphone body 1 move in X axis direction, and Y axis fixed screw 4 is connected in screw thread in microphone fixing block 2 inside, and X axis fixed screw 8 is connected in screw thread in installation support 10 inside, and Y axis adjusting screw 6 is also connected in screw thread in microphone fixing block 2 inside, when needing to adjust microphone position in Y axis direction, first loosens Y axis fixed screw 4, then turns Y axis adjusting screw 6, because Y axis adjusting screw 6 is connected in screw thread in microphone fixing block 2 inside, so Y axis adjusting screw 6 will drive microphone move in Y axis direction in microphone fixing block 2, after adjusting position, tightens Y axis fixed screw 4, thereby fixed microphone in Y axis direction's position, and simultaneously worth mentioning is, when rotating Y axis adjusting screw 6 and X axis adjusting screw 9 every rotation, microphone position changes 0.5mm.

[0024] Refer to Figure 1 - Figure 3, the microphone body 1 is provided with a mounting groove 13, which has an important role. The microphone is inserted into the placing groove 14 in the microphone fixing block 2, and then the mounting groove 13 is used to make the clamping of the clamping ring 15 fixedly connected in the microphone fixing block 2. In this way, the consistency of the microphone installation position can be maintained, and the test error caused by the difference in installation position can be effectively reduced. The fixed screw one 3 is threadedly connected in the microphone fixing block 2. After the microphone is installed, the fixed screw one 3 can be twisted to clamp the microphone body 1, so that the microphone is fixed on the microphone fixing block 2. At the same time, the upper surface of the microphone body 1 is provided with a cover plate 5. The cover plate 5 cooperates with the fixed screw one 3 during the microphone fixing process, further ensures the stability of the microphone fixing block 2, and prevents the microphone from being displaced due to vibration during the test process.

[0025] Working principle: when using the device, first insert the microphone into the placing groove 14 in the microphone fixing block 2, and then make the clamping of the clamping ring 15 in the microphone fixing block 2 through the installation of the microphone internal mounting groove 13, so as to maintain the consistency of the microphone installation position, reduce the test error caused by the difference in installation position, and realize the fixation of the microphone on the microphone fixing block 2 after the microphone is installed.

[0026] When the position of the microphone needs to be adjusted in the X-axis direction, first loosen the X-axis fixed screw 8 in the installation support 10, and then twist the X-axis adjusting screw 9. Since the X-axis adjusting screw 9 is threadedly connected in the installation support 10, the X-axis adjusting screw 9 will move in the installation support 10, thereby driving the X-axis adjusting block 7 to move in one end of the X-axis direction. When the X-axis adjusting block 7 moves, the microphone fixing block 2 and the microphone body 1 fixed therein will move in the X-axis direction. After adjusting the position, tighten the X-axis fixed screw 8 to fix the X-axis adjusting block 7, thereby fixing the position of the microphone in the X-axis direction. When the position of the microphone needs to be adjusted in the Y-axis direction, first loosen the Y-axis fixed screw 4, and then twist the Y-axis adjusting screw 6. Since the Y-axis adjusting screw 6 is threadedly connected in the microphone fixing block 2, the Y-axis adjusting screw 6 will drive the microphone to move in the Y-axis direction in the microphone fixing block 2. After adjusting the position, loosen the Y-axis fixed screw 4, thereby fixing the position of the microphone in the X-axis direction. At the same time, when the Y-axis adjusting screw 6 and the X-axis adjusting screw 9 are rotated by one revolution, the position of the microphone changes by 0.5mm.

[0027] When the position of the microphone needs to be adjusted as a whole, the air cylinder 11 is started under the control of the electromagnetic valve, at this time, through the extension and retraction of the air cylinder 11, the mounting bracket 10 and the microphone fixing block 2 and the microphone body 1 mounted thereon can be driven to move as a whole, so that the microphone gradually approaches the product sound outlet, through the accurate control of the air cylinder 11, it can be ensured that the distance between the microphone and the product sound outlet is within a suitable range, which can effectively receive the audio signal, and will not be disturbed by the product itself due to too close distance, effectively ensuring that the test result can accurately reflect the audio performance of the product.

[0028] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
