Private Mold Protection
Private mold projects are protected by three layers, all written into the same contract:
- Non-disclosure agreement (NDA): Signed before cooperation begins, covering drawings, CAD files, acoustic parameters and firmware.
- Tooling ownership and exclusivity clauses: Tooling ownership is stated explicitly, and the mold may not be used for any other customer.
- Exclusive protection of customer audio assets: Audio files supplied by the customer are used exclusively for that project.
- Patents held: 40 patents — 39 design patents plus one invention patent, "Audio Processing Apparatus and Method" (ZL2015 1 1027770.6), covering core audio processing technology.
- Independently verifiable: Design patents are publicly searchable — for example the HFD-R7 is ZL2022 3 0310386.1. A contract can be signed by anyone, but only a granted patent can be checked by a third party.
Production Capacity and Quality Control
- Three production sites totaling approximately 6,000 m² in Bao'an District, Shenzhen
- Six production lines — four assembly and two packaging
- 200+ employees, including 20+ R&D engineers
- 3,000,000 units annual capacity
- 46 pieces of production and testing equipment, including an in-house reliability lab covering temperature/humidity, salt spray, drop, vibration, key-life and air-tightness testing
- In-house processes: Assembly, inspection and packaging are all performed in-house, with no outsourced processes
In-house AQL standard:
|
Stage
|
Standard
|
|
Incoming material (IQC)
|
0 critical / 0.65 major / 1.0–1.5 minor
|
|
In-process (IPQC)
|
First-article inspection RE=0; inspection every 2 hours
|
|
Finished goods
|
100% final inspection before shipment
|
An AQL of zero for critical defects means zero tolerance — not "very few".
