Welcome to Original Song Electronic Technology Co., Ltd.

  • 1 、How is the quotation calculated?

    The quotation is comprehensively calculated based on inductor specifications, core material, order quantity, and customization process
  • 2 、Without acoustic design drawings, can you provide solution support?

    With our own team of R&D engineers, customers only need to provide the speaker parameters and desired acoustic effects. We can provide a free crossover matching solution, offering a one-stop solution to acoustic tuning challenges.
  • 3 、Can we handle export orders? Do you have relevant certifications?

    Support domestic and international trade, cross-border orders, and adapt to markets in Africa, the Middle East, Asia, Southeast Asia, Europe, and America.
  • 4 、Will your supply prices fluctuate frequently due to rising raw material costs?

    By maintaining long-term inventory of copper and magnetic core raw materials, we experience less price fluctuation compared to small workshops, enabling us to provide stable quotations to long-term customers and reduce the impact of cost fluctuations.
  • 5 、What is the normal delivery cycle for bulk orders?

    Standard in-stock items are shipped within 7 days; customized bulk orders take 25-45 days. With ample reserves of raw materials, we can ensure stable production scheduling and rapid delivery even during peak periods.
  • 6 、What causes the noise and distortion in the frequency divider, and how does the after-sales service

    This issue is often caused by inductive core loss and circuit matching deviations. We conduct a full inspection before shipment to avoid this problem. If quality issues occur in batches, we offer free rework, replacement with new products, and provide one-on-one debugging solutions from technical engineers.
  • 7 、Can the product meet automotive-grade standards?

    Certainly, we can produce automotive-grade crossover inductors and crossovers suitable for new energy vehicle audio systems, meeting high-precision and low-interference requirements and aligning with the stringent acoustic standards of automakers.
  • 8 、What is the quality assurance for your frequency-dividing inductor/frequency divider?

    Equipped with fully automatic winding equipment and integrated frequency response testing instruments, we implement comprehensive quality control throughout the entire process. We strictly control the inductance Q value and impedance error, conduct full inspections before shipment, and ensure zero-defect delivery. Our raw materials (copper, iron-silicon-aluminum magnetic cores) are kept in constant stock, with stable performance and low distortion, meeting domestic safety regulations as well as European and American EMC electromagnetic compatibility standards.
  • 9 、What is the minimum order quantity? Can small-batch orders be accepted?

    Regular finished products have no excessively high minimum order quantity (MOQ) threshold; customized products are divided into general-purpose and non-standard types. Small-batch modification orders can be undertaken by flexible production lines, meeting the needs of brand trial orders and new product testing.
  • 10 、How long does it take to customize and produce a sample? Is there a charge for the sample?

    For regular specification samples, delivery takes 3-5 days; for special magnetic cores and non-standard inductors, it takes about 7 days. A sample fee will be charged for the first sample, but it can be refunded after placing a bulk order.
