The SY Dolls Rotating Tongue function is a newly developed electronic upgrade designed for M-Series movable jaw silicone heads. Instead of relying on a static structure, this feature introduces controlled tongue movement to improve interaction and realism.
Unlike exaggerated mechanical motion, this system focuses on rhythm, precision, and user control. As a result, it suits users who prefer adjustable movement rather than a fixed pattern.
What Is the Rotating Tongue Function?
The rotating tongue function is an internal electronic mechanism created specifically for SY Dolls movable jaw heads. Once connected to power, the tongue performs two independent motion modes:
- Circular rotation with multiple speed levels
- Smooth in-and-out movement with adjustable frequency
Because both modes operate separately, users can easily switch between them depending on preference. In addition, the transition between speeds remains smooth and stable.
How the Electronic Tongue System Is Used
SY Dolls includes a compact remote control with three clearly marked buttons:
- Rotation mode: activates circular motion and cycles speed levels
- In-and-out mode: controls tongue extension and retraction speed
- Stop/Pause: immediately stops all movement
This layout keeps operation simple. At the same time, it allows precise control without complex settings.
Designed for M-Series Movable Jaw Heads
The SY Dolls rotating tongue upgrade works exclusively with M-Series heads, which feature a movable jaw and realistic oral structure. The internal design preserves the head’s appearance while integrating electronic movement seamlessly.
For this reason, the upgrade does not affect external realism or daily handling.
Usage and Care Recommendations
To maintain stable performance and extend product life:
- Disconnect the power supply when the function is not in use
- Keep the input port dry during cleaning
- Avoid direct contact between water and the power connection
Following these steps helps prevent electrical issues over long-term use.
Why This Upgrade Matters
Compared with traditional silicone heads, this electronic tongue upgrade adds an extra layer of interaction while keeping operation intuitive. Therefore, it works well for users interested in advanced features without unnecessary complexity.
The SY Dolls Rotating Tongue function offers a balanced combination of realism, control, and reliability, making it a practical choice for M-Series head owners.
