OMNIA
Home speaker in a small form factor
* ONGOING PROJECT*
CONTEXT
This project wants to unify the power and sound quality of a standard 3-way speaker with the convenience of a compact and portable object.
​
Using efficient and high-quality drivers the goal is to recreate the precision and the power of a HI-FI speaker in a compact and unlike anything before.
​
The project is developed using fusion 360 for design, Sigma studio and Vituix Cad to lead the development of all audio aspects.

BRIEF
A portable speaker shouldn’t be placed in a correct way to sound good and powerful.
​
Nothing on the market can give you powerful sound, high detailed sound and portability at the same time.
​
So, I created a sound system that could be placed anywhere with a HI-FI response, powerful sound and versatilyty in a small and inovative design

CONCEPT
The project started with choosing the right layout of the hardware. The omnidirectional one is the best for HI-RES and power in all the environments.
The component selected to create the speaker are:
-
1” Tweeter SB Acoustic
-
2” Mid-range dome Dayton audio
-
5-1/2” Subwoofer Peerless
-
50W X 4 channels amplifier with DSP
-
6S BMS









To create the speaker, I put the first three components in a vertical disposition, creating a “tower speaker” but the subwoofer cabinet would not be big enough for a quality response.
To solve this problem, I attempt lots of configurations, trying to create a down-firing subwoofer layout. Due to technical issues this type of cabinet was scrapped.
For the final solution I designed a proper subwoofer cabinet, and I put in that all the remaining components and to reduce the cabinet volume much more I used two Passive radiators.
PRE-PRODUCTION PROTOTYPE
For the design I take advantage of the two different ways used to generate sound: omnidirectional and direct configurations.
​
To imprint in the project two main concepts, separation and lightness.
To do so, the main inspiration is the Asian pagodas, concentrating the main components on the center and leverage the omnidirectional diffusers support to increase the idea of dividing and elevation of the product.


The pagoda's roof plays a relevant role in protecting the building during rainstorms and earthquakes, as well as carrying a strong symbolic and spiritual meaning.
The main box is parallelepiped shaped, in 2mm iron sheet, bent and soldered on the side to create a closed and sealed volume.
The internal walls are coated with a bituminous sound isolation foil, to maximize quality response.

The subwoofer on the frontal sheet and the mid and tweeter on the top one. The passives radiators are mounted on the faces to use the non direct subwoofer's power

The omnidirectional diffusers are mounted on top, supported by an aluminum piece to recreate the roof effect, sligltly larger than the main box.

The main cabinet is surrounded by two U shaper pieces in aluminum, that have two main goals:
-
Support the mesh sheets covering the drivers and the back panel
-
Combined with the upper aluminum support, it enable to the speaker to be place in any position possible, vertical or horizontal to adapt the shape to the environment.
