TWS Phones Speaker Assembly Jetting Valve​ Piezoelectric Valve 1.2KHz

Low maintenance cost Jetting valves​ in Miniature Speaker Assembly of TWS/Phones

The KPS2000 piezo jet valve delivers high-precision, non-contact adhesive dispensing for micro speaker assembly in smartphones, TWS earbuds, and wearables. It ensures excellent dot consistency with no satellite droplets, supporting clean and accurate bonding of membranes, coils, and housings. Widely used in China, Korea, and Vietnam, it's ideal for high-speed automated lines.

Core Advantages

• Non-contact high-frequency dispensing: suitable for small structural components, avoiding contact that may cause deviation or damage to the membrane and coil
• Precise control of micro-glue volume: nanoliter dispensing capability to ensure dispensing consistency and batch yield
• Quick response, precise positioning
• Quick-detachable flow channel + ADJ top calibration function: simplify disassembly and cleaning steps

Main appliaction

• TWS earphone speaker module bonding (housing + FPC + membrane)
• Smart watch sound cavity dispensing packaging
• Mobile phone earpiece speaker module voice coil support bonding

FAQ

Q1: How does the KPS2000 piezo jet valve ensure high dispensing consistency in micro speaker applications?
A1: The KPS2000 features a coaxial needle guidance structure and micron-level adjustment mechanism, ensuring stable, repeatable adhesive dots with no satellite droplets. This is especially important for diaphragm and voice coil bonding, where precision directly affects acoustic performance.

Q2: Can the KPS2000 adapt to different adhesive types used in speaker production?
A2: Yes, the KPS2000 supports a wide range of adhesives including epoxy, UV-curable, silicone, and thermal cure adhesives. Its adjustable jetting parameters allow quick adaptation to different viscosities and curing requirements commonly used in speaker assembly.

Q3: What is the typical maintenance or cleaning process for the KPS2000 in mass production?
A3: Thanks to its quick-release flow path module, the KPS2000 can be disassembled, cleaned, and reassembled in under 2 minutes, without the need for recalibration. This minimizes downtime and keeps production efficiency high.

Q4: How does the supplier support process validation and integration for new speaker projects?
A4: We provide full application support, including sample testing, parameter optimization, and onsite/remote commissioning. Our engineers work closely with customers to ensure smooth line integration and stable dispensing results from NPI to mass production.

Q5: What markets are currently using the KPS2000 for micro speaker production?
A5: The KPS2000 is widely adopted by top speaker module manufacturers in China, Vietnam, and Korea, especially for TWS earbuds, smartphones, and wearables, where precision, repeatability, and production speed are critical.
