Products Description
The dual frequency design uses stacked piezoelectric layers tuned to different resonant points. When the driver outputs 1 MHz, the transducer delivers energy to the deeper dermis layer. When switched to 3 MHz, energy concentrates at a shallower depth suitable for facial treatments.
As a dual-frequency skincare transducer, this unit shares a common housing and electrode structure. The mechanical design uses 304 stainless steel for the housing, with PZT-4 piezoelectric elements providing reliable energy conversion.
If you currently use single-frequency transducers, this dual-frequency transducer can replace them with appropriate driver adjustments. The impedance matching can be customized to work with your existing circuit design. Provide your driver's output specifications, and we'll confirm compatibility.

Product Application
This dual-frequency ultrasonic beauty transducer serves aesthetic equipment manufacturers building devices for
Facial Skin Tightening: The 3 MHz channel delivers a controlled thermal effect to the superficial dermis, supporting collagen remodeling in facial areas. This dual-frequency facial transducer design targets the epidermis and upper dermis with precise energy delivery.
Body Contouring Treatments: The 1 MHz channel penetrates deeper for bulk tissue heating in body applications. The 1 MHz ultrasonic beauty head provides the penetration depth required for subcutaneous tissue treatment. For shallower treatments, the 3 MHz ultrasonic beauty head delivers concentrated energy to superficial layers.
Ultrasonic Facial Devices: Multi-function aesthetic equipment combining deep cleaning, essence infusion, and skin firming. This dual-frequency facial transducer design supports multiple treatment protocols from a single handpiece.
Professional Salon Equipment: High-duty-cycle applications requiring consistent power output
Home Use Beauty Devices: Compact designs with controlled power output for consumer safety
The 1 MHz and 3 MHz dual-frequency ultrasonic beauty transducer approach allows device manufacturers to offer multiple treatment modes from a single handpiece, simplifying the user interface while expanding treatment capabilities.

FAQ
Q: What is the difference between 1 MHz and 3 MHz frequencies?
A: The 1 MHz frequency penetrates deeper (approximately 10 mm) and targets the deeper dermis and subcutaneous layers. It's suitable for body treatments and larger treatment areas. The 3 MHz frequency operates at a shallower depth (approximately 3 mm) and provides more concentrated energy for facial treatments and delicate areas. The dual frequency design allows a single device to offer both treatment modes.
Q: Can you provide impedance matching to our specific driver?
A: Yes. We optimize the transducer impedance to work with your driver circuit specifications. Please provide your driver's output frequency, voltage, and current parameters, and we'll run simulations to confirm compatibility before sending samples.
Q: What is the minimum order quantity?
A: Standard MOQ is 10 units. For custom specifications, MOQ is also 10 units. We accept smaller quantities for sample orders.
Q: Do you provide test reports with the shipment?
A: Yes, Batch CoC (Certificate of Conformance) is included with each order. Full test reports with individual unit data (frequency, impedance, capacitance) are available upon request.
Q: What is the expected operational lifespan?
A: Internal testing shows >5000 hours before performance degradation under standard operating conditions. Actual lifespan depends on your power levels, duty cycle, and coupling media used. We recommend planning for component replacement schedules in your device service maintenance.
Q: Can this replace our current single-frequency transducers?
A: We provide compatibility consultation for replacement applications. Share your current transducer specifications and driver parameters, and our engineering team will assess whether modifications are needed for your system.
