EarbudSource — Custom Earbuds. Built for Your Brand.
INDUSTRIAL DESIGN & MECHANICAL ENGINEERING

Turn the wearing concept into a buildable product architecture.

Coordinate earbud and charging-case form, fit, internal stack, materials, interfaces, tolerances and assembly before geometry is released for tooling.

Earbud and charging-case housing prototypes, internal parts and measuring tools reviewed during mechanical engineering
Engineering scope and evidence are confirmed for the shortlisted model, configuration and supplier.
ENGINEERING PRINCIPLE

Resolve the interfaces before the next investment gate.

A visually attractive housing still has to contain the battery, PCB, antenna, microphones, driver, charging contacts and fastening features. Fit, acoustic volume, wireless clearance and assembly access must be reviewed together.

ENGINEERING WORKSTREAMS

Each activity needs a defined output.

The actual work depends on whether the project uses an existing model, a modified architecture or a new development route.

01

Product architecture

Define earbud type, wearing concept, charging-case structure and internal zones

Architecture layout and open constraints
02

Industrial design

Develop proportions, surfaces, controls, light windows and CMF direction

Reviewed design surfaces and appearance intent
03

Fit & ergonomics

Review contact points, projection, weight distribution, ear-tip or hook geometry

Fit samples and evaluation criteria
04

Mechanical layout

Place internal components, charging interfaces, fastening and sealing features

Mechanical definition and interface control
05

Tolerance & assembly

Review gaps, flushness, hinge, magnets, contacts and assembly sequence

Tolerance risks and build issue list
06

DFM & release

Check draft, parting line, wall thickness, ribs, snaps and tool access

Geometry ready for tooling-feasibility review
INTERFACE RISKS

Review what this discipline can affect.

A local change can create issues in another part of the product system.

01

Mechanics × acoustics

Internal volume, vents and seal affect the tuning route

02

Housing × antenna

Materials, coatings and internal metal affect wireless behavior

03

Battery × thickness

Capacity, runtime target, weight and projection compete for space

04

Case × charging

Contacts, magnets, alignment and lid geometry must work together
