Acoustic target
Define application, product position, reference sound and priority tradeoffs
Target direction and comparison referencesTWS ACOUSTIC ENGINEERING
Control the acoustic system—not only the EQ curve.
Review driver, cavity, venting, mesh, ear tips, seal, microphone path and tuning candidates against the product position and measurable approval criteria.
ENGINEERING PRINCIPLE
Resolve the interfaces before the next investment gate.
Earbud sound is shaped by mechanical volume, driver selection, venting, mesh, seal and wearing position. A tuning change may require mechanical or firmware work, and approval should combine measurements with repeatable listening references.

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.
Driver & cavity
Review driver, rear and front volume, damping and vent structure
Acoustic architecture and constraintsSeal & wearing
Evaluate ear tips, insertion, leakage, open-ear geometry or fit variation
Fit-related acoustic risk listMicrophone path
Review call, feedback or feed-forward microphone ports and mesh
Microphone-path definitionTuning candidates
Develop supported DSP / EQ and mechanical tuning combinations
Versioned tuning samplesApproval criteria
Compare frequency response, balance, distortion where applicable and listening review
Approved tuning reference and limitsINTERFACE RISKS
Review what this discipline can affect.
A local change can create issues in another part of the product system.
Fit × response
Seal and insertion depth can change bass and tonal balance
Mesh × output
Protective materials add acoustic resistance and variation
Cavity × mechanics
Internal ribs, battery and PCB restrict acoustic volume
Firmware × tuning
DSP, volume steps and modes must match the approved target
