Shining 3D: Creating a Speaker Mount with EinScan Pro 2X

In this article, we will cover an example of using the Shining 3D EinScan Pro 2X scanner: creating a tweeter mount for a car audio system on a complex curved surface of a rack using 3D scanning – an example from Katsuya Tanabika’s practice.

Katsuya loves bicycles and cars. On his blog, he shares his projects using Fusion 360, 3D printing and EinScan Pro 2X.

A new approach to tweeter installation

A tweeter is the high-frequency driver of a car audio system and plays an important role in sound quality. There are several approaches to installing a tweeter in a car:

  • The easiest way is to mount the tweeter in its regular position but sometimes this is not advantageous for sound quality.
  • On the dashboard.
  • Embedding the tweeter in the front pillar is the best solution in terms of sound quality but it’s a very costly one.

With 3D scanning and 3D printing technologies, a cost-effective, beautiful and efficient solution can be found to install a tweeter on any car. A 3D printed tweeter mount can simply be attached to the front strut in a way that looks neat and aesthetically pleasing.

How to design a twitter mount using a 3D scanner

There are many tricks to using a 3D scanner. Black objects can be difficult to scan but by adapting the brightness of the EinScan Pro 2X, you can effectively capture surfaces. The scanning process was completed in about 5 minutes.

In this case, there is not much data, since the project involves a small-sized tweeter.

The positioning cannot be corrected directly in ExScan Pro. After specifying the orientation, the data can be imported into Fusion360.

The CX-8 front strut curved surface data is imported into Fusion360 using “Insert Grid”.

The tweeter module is added to the current design using “Insert into Current Design”.

The position of the tweeter housings should be determined by checking the image as a whole and making minor adjustments. If the tweeter modules are not disconnected, they cannot be separated.

The front rack mesh data must be converted to “Mesh to BRep”.

The conversion process takes some time depending on the characteristics of the PC, so patience may be required.

The tweeter body can now be trimmed to fit the front rack perfectly.

Using the “Split Body” function will cut the tweeter housing on the curved surface of the front post.

You must first select the “Extend Split Tool” field.

You can then select the tweeter housing as the “Split Body” and the curved front post surface as the “Split Tool”.

After selecting “OK,” the PC will begin the calculation.

If successful, the curved surface of the front post can be cut.

A flange is needed to secure the tweeter mount to the front post.

Locations for the screw mounts should be prudently placed so that it will not cause installation difficulties.

Flanges can be drawn on the front of the enclosure, according to the screw specifications, and made solid, “extrusion” or other methods.

At this point it should not be “joined” but rather turned into a “new body”.

It is very important to determine the angle of the flange because the screws are screwed through the hole in the tweeter body. In this particular case, the screwdriver will either not go through or will be too angled, making it very difficult to screw the screws in.

After selecting one location, you can select other locations, using the “Move Copy” function.

To make it easier to adjust the position angle, it is better to change the “Rotation Settings”. This can be accomplished by clicking the “Rotation Settings” symbol, then the center of the cylinder, and finally the “Rotation Settings” checkbox to apply the settings.

Once the digital design process is complete in Fusion 360, the tweeter mount can be 3D printed and easily installed.
