Abstract
Description
Technical Field
[0001] The utility model relates to the field of earphone product positioning structures, in particular to an automatic positioning fixture for special-shaped earphones. Background Art
[0002] In the production of earphones, a diaphragm is usually placed at the sound outlet to achieve the desired effect (such as dustproof and waterproof). However, in actual installation, its volume is relatively small, about a circular sheet with a diameter of 1.5 mm (especially for in-ear earphones).
[0003] In an earphone with a special structure, there is a certain inclination, so it is difficult to achieve standardized positioning using existing jigs, which seriously affects the installation efficiency of the diaphragm. Utility Model Content
[0004] The main purpose of the utility model is to propose an automatic positioning fixture for special-shaped earphones, aiming to improve the positioning fixture of the earphone shell, thereby realizing the standardized positioning of the earphone and placing the primary sound hole horizontally, thereby facilitating the installation of the diaphragm.
[0005] To achieve the above purpose, the utility model provides an automatic positioning fixture for special-shaped earphones, comprising:
[0006] A base, wherein a protruding fixing seat is provided in the middle of the base, and a concave positioning groove is provided on the side wall of the fixing seat. There are a plurality of positioning grooves, and the positioning grooves are used to limit the neck of the earphone shell;
[0007] The adjusting seat is slidably mounted on the base, the adjusting seat is arranged opposite to the fixing seat, the adjusting seat is provided with a clamping seat arranged opposite to the positioning groove, and the lower wall of the clamping seat is provided with an avoidance groove,
[0008] When the adjustment seat slides to a predetermined position, the lower wall of the seat abuts against the upper wall of the rear end of the earphone shell.
[0009] In the actual design, the positioning groove and the avoidance groove of the imitation structure are used to limit the earphone shell. At the same time, the sliding setting of the adjustment seat can realize the simultaneous limitation of multiple earphone shells. The setting of the avoidance groove can realize the further tilting of the earphone shell and set the sound hole at a predetermined position (for example, horizontal or inclined).

[0016] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0017] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0018] like Figures 1 to 3 As shown, an automatic positioning fixture for special-shaped earphones includes:
[0019] A base 1, wherein a protruding fixing seat 11 is provided in the middle of the base 1, and a concave positioning groove 21 is provided on the side wall of the fixing seat 11. There are a plurality of positioning grooves 21, and the positioning grooves 21 are used to limit the neck of the earphone shell;
[0020] The adjusting seat 12 is slidably mounted on the base 1. The adjusting seat 12 is arranged opposite to the fixing seat 11. The adjusting seat 12 is provided with a clamping seat 22 arranged opposite to the positioning groove 21. The lower wall of the clamping seat 22 is provided with an avoidance groove 221.
[0021] When the adjustment seat 12 slides to a predetermined position, the lower wall of the clamping seat 22 abuts against the upper wall of the rear end of the earphone shell.
[0022] In the actual design, the positioning groove 21 and the avoidance groove 221 of the imitation structure are used to limit the earphone shell. At the same time, through the sliding setting of the adjustment seat 12, the simultaneous limitation of multiple earphone shells can be achieved. The setting of the avoidance groove 221 can realize the further tilting of the earphone shell and set the sound hole at a predetermined position (for example, horizontal or inclined).
[0023] Specifically, two sets of positioning grooves 21 are provided on the two side walls of the fixing seat 11, and the adjustment seat 12 is provided on both sides of the fixing seat 11 when relative to each other. The adjustment seat 12 is symmetrically arranged with respect to the axis of the fixing seat 11, so that a single fixture can hold more earphones, and when installing, the two diaphragms can be directly installed.
[0024] Furthermore, the position of the avoidance groove 221 is also concavely provided with an arc groove 31 arranged opposite to the positioning groove 21. The setting of the arc groove 31 can facilitate observation of the limit position of the earphone shell.
[0025] In the embodiment of the utility model, the fixing seat 11 is provided with a gradually decreasing inclined surface 32 toward the sliding seat. Of course, the bottom of the earphone shell may not be inclined, so the setting of the inclined surface 32 can be suitable for earphone shells with an inclination, so that the sound outlet channel can be set horizontally. Of course, the sound outlet channel can also be set inclined, which can also facilitate the attachment of the diaphragm.
[0026] Specifically, the positioning groove 21 is arranged to penetrate along the width direction of the fixing seat 11 , and a chamfer 4 is arranged at the end of the positioning groove 21 . The chamfer 4 is arranged to facilitate the limiting of the cylindrical neck.
[0027] In the embodiment of the utility model, the base 1 is provided with a guide rail 51 extending along its width, and the adjustment seat 12 is provided with a slider 52 matching the guide rail, wherein the sliding of the adjustment seat 12 can be fixed by the device itself, or a telescopic motor or spring can be used to achieve its sliding.
[0028] Furthermore, the base 1 is provided with a telescopic motor or a spring for driving the adjustment seat 12 to move.
[0029] In an embodiment of the utility model, the base is installed on a longitudinal movable frame, which includes a longitudinal movable guide rail 61, a longitudinal slider slidably installed on the longitudinal movable guide rail, and a longitudinal screw pair 63 driving the longitudinal slider 62, thereby driving the fixture to move to a position below the suction cup.
[0030] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
