This article highlights China Future Sound’s approach to custom audio manufacturing, detailing their specialized solutions for automotive, marine, and other sectors.
China Future Sound provides customizable audio solutions across multiple sectors, recognizing that each client presents unique requirements. The company’s manufacturing capabilities extend to several product categories:
- Automotive amplifiers designed to deliver performance and distortion-free audio
- Car audio systems providing clarity and power for vehicle applications
- Marine audio equipment built to deliver high-performance sound in demanding maritime environments
- Professional audio gear for studio and stage applications requiring precision and clarity
- Speaker enclosures designed for optimal acoustic performance
The company’s approach addresses the specific needs of OEM buyers and product managers seeking scalable audio manufacturing partnerships. Founded in 2003, China Future Sound has established the United States as its largest market, with additional primary markets including Ghana, Nigeria, Turkey, and Russia.
The Jiashan facility follows a detailed amplifier production procedure comprising six stages: SMT (Surface Mount Technology), DIP (dual in-line package), PCBA testing, Assembly, Aging and Testing, and Packing. Each stage incorporates specific inspection processes to ensure product reliability and performance.
The SMT stage includes SPI and SMT AOI inspection processes. The DIP stage incorporates insertion AOI inspection. PCBA testing includes after wave soldering AOI, FCT (Functional Circuit Test), and AP testing (Audio Precision). The Assembly stage includes FCT inspection. Aging and Testing stages include aging testing and AP testing. The Packing stage concludes with pure sound testing.
China Future Sound maintains ISO9001-2015 Quality Management System certification, with all processes controlled according to documented regulations. The company employs ERP (Enterprise Resource Planning) and WMS (Warehouse Management System) to manage inventory and implement FIFO (First-In-First-Out) control for all materials and products. Production processes utilize KLIPPEL QC combined with golden samples for consistency control.
The quality control system includes multiple inspection points: IQC (Incoming Quality Control) conducts random inspections on all incoming materials, IPQC (In-Process Quality Control) monitors the mass production process, and FQC (Final Quality Control) inspects finished products. A reliability laboratory conducts regular reliability tests on products according to design requirements. The company adopts barcodes and QR codes to control the testing route in production, binding test data with the barcode system to ensure product traceability.
The company operates with an R&D team of over 20 people, organized into specialized groups: an Acoustics Team, an Electronics Team, a Structure Team, and a Software Development Team. The engineering teams bring extensive product R&D experience in the audio industry.
The Acoustics Team employs finite element simulation software to simulate magnetic circuits and speaker vibration systems based on performance requirements. The team uses KLIPPEL R&D to test samples, ensuring designed performance requirements are met. Short-term destructive power tests and long-term power tests simulate extended usage environments to ensure product reliability. Golden sample management ensures consistency between mass-produced products and samples.
The Electronics Team conducts rapid design modeling based on performance requirements, using electronic schematic diagrams and design simulation software to simulate circuit and programmable logic system performance. Testing equipment includes the AP Audio Precision system, SMD Amplifier Dyno AD-1, adjustable frequency power supply (eec6900s), and programmable power supply (SPS5000) to verify samples meet designed performance requirements.
