Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing technology, and in particular to a fixture for processing high-amplitude super-linear loudspeaker housings. Background Technology

[0002] A loudspeaker, also known as a horn, is simply an electroacoustic device that converts electrical signals into sound, and is an important component of an audio system. As one of the electroacoustic transducers that converts electrical energy into sound energy, the quality and characteristics of a loudspeaker play a decisive role in the sound quality of the entire audio system.

[0003] Loudspeakers typically use a single coil to drive the diaphragm. When the signal is too large or the amplification is too strong, the diaphragm experiences uneven stress, which can cause resonance and sound distortion. Super-linear loudspeakers, on the other hand, use two coils to drive the diaphragm, balancing the stress on the diaphragm as much as possible and enhancing the diaphragm's amplitude, resulting in better sound.

[0004] When producing high-amplitude super-linear loudspeakers, they need to be installed inside the loudspeaker housing. Therefore, the loudspeaker housing needs to be clamped in advance. However, conventional clamps are not convenient for adapting and fixing housings of different sizes, and they are prone to shaking, which affects processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a fixture for machining high-amplitude superlinear loudspeaker housings, thereby solving the problems mentioned in the background section.

[0006] A fixture for machining a high-amplitude superlinear loudspeaker housing includes a base and a clamping mechanism mounted on the base. The clamping mechanism includes a placement platform, a clamping part, an adjusting part, a fixing plate, a cylinder, and a connecting shaft. The placement platform is fixedly mounted on the base. The adjusting part consists of four sets of equally angularly distributed grooves in the placement platform, and a limiting port is provided at one end of the adjusting part. The clamping part is slidably engaged at the end of the adjusting part facing the center of the placement platform. The fixing plate is fixedly mounted on the edge of the placement platform and is located at the limiting port of the adjusting part to stabilize and limit the adjusting part.

[0007] By adopting the above technical solution, the device can easily apply pressure to position speaker housings of different sizes, with fast adjustment speed, high positioning efficiency, and convenient operation by staff.

[0008] The placement platform has a recessed support groove in the middle, and the upper edge of the support groove is chamfered.

[0009] By adopting the above technical solution, the adjustment part and the upper edge of the bearing groove can be fitted and slid together with the chamfered edge.

[0010] The end face of the clamping part facing the center of the placement platform is set as an arc-shaped concave surface.

[0011] By adopting the above technical solution, it is possible to limit and clamp the speaker housing.

[0012] The bottom surface of the end of the adjustment part with the limiting port is set as an inclined surface and can be fitted to the chamfered edge.

[0013] By adopting the above technical solution, it is easier to adjust the clamping of the adjustment part on the speaker housing.

[0014] The width of the groove of the placement platform is adapted to the thickness of the adjustment part, and the width of the limiting port of the adjustment part is adapted to the thickness of the fixing plate.

[0015] By adopting the above technical solution, the stability of the movement of the adjusting part is ensured.

[0016] The beneficial effects of this utility model of a fixture for machining high-amplitude super-linear loudspeaker housings are:

[0017] The speaker housing is placed in the middle of the support groove. The drive cylinder pulls the adjustment part down through the connecting axis. The inclined surface at the bottom of one end of the adjustment part fits with the chamfered edge of the placement platform. At this time, the adjustment part moves down along the clamping part and pushes the clamping part to move towards the center of the placement platform until the speaker housing is clamped from the side by the clamping part. This device is convenient for applying pressure and positioning speaker housings of different sizes. It has a fast adjustment speed, high positioning efficiency, and is easy for operators to operate.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-2A fixture for processing a high-amplitude superlinear loudspeaker housing includes a base 1 and a clamping mechanism mounted on the base 1. The clamping mechanism includes a placement platform 2, a clamping part 3, an adjusting part 4, a fixing plate 5, a cylinder 6, and a connecting shaft 7. The placement platform 2 is fixedly mounted on the base 1. The adjusting part 4 consists of four sets of equal-angled grooves 202 in the placement platform 2, and a limiting port is opened at one end of the adjusting part 4. The clamping part 3 is slidably engaged at the end of the adjusting part 4 facing the center of the placement platform 2. The fixing plate 5 is fixedly mounted on the edge of the placement platform 2 and is located at the limiting port of the adjusting part 4 to stabilize and limit the adjusting part 4.

[0023] Place the speaker housing in the middle of the support groove 201. Drive the cylinder 6 to pull the adjustment part 4 downward through the connecting shaft 7. The inclined surface at the bottom of one end of the adjustment part 4 is in contact with the chamfered edge 203 of the placement platform 2. At this time, the adjustment part 4 will move downward along the clamping part 3 and push the clamping part 3 to move towards the center of the placement platform 2 until the speaker housing is clamped from the side by the clamping part 3.

[0024] This device facilitates the pressure application and positioning of speaker housings of different sizes, with fast adjustment speed, high positioning efficiency, and convenient operation for staff.

[0025] The middle of the placement platform 2 is recessed with a support groove 201, and the upper edge of the support groove 201 is chamfered 203. The speaker housing can be placed in the support groove 201, and the speaker housing can be clamped from the side by pushing the clamping part 3 to move. The end face of the clamping part 3 facing the center of the placement platform 2 is provided with an arc-shaped concave surface to facilitate positioning and clamping of the speaker housing.

[0026] The bottom surface of the end of the adjustment part 4 with the limiting port is set as an inclined surface and can fit against the chamfered edge 203. When the adjustment part 4 moves downward, it can move towards the center point of the placement platform 2 by cooperating with its inclined surface and the chamfered edge 203 of the placement platform 2, thereby clamping the speaker housing.

[0027] The width of the slide 202 of the placement platform 2 is adapted to the thickness of the adjustment part 4, and the width of the limiting port of the adjustment part 4 is adapted to the thickness of the fixing plate 5; ensuring that the adjustment part 4 can move normally up and down and move toward the center of the placement platform 2 without shaking.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
