Products and Services

Changzhou Fhd Electronics Co., Ltd. offers a comprehensive range of acoustic components and related services that cater to a broad spectrum of industrial and consumer needs.

1. Acoustic Components

FHD Electronics manufactures a diverse portfolio of acoustic components, each designed for specific functionalities and applications:

• Buzzers: This is a core product line, encompassing various types:
  • Electromagnetic Buzzers: Highly reliable and durable, these buzzers boast a long service life of over 10,000 hours of continuous use due to the absence of single-sided contact. They produce no arc or radio frequency (RF) noise, ensuring no interference with other electronic components. They are also resistant to large vibrations from loosening and can produce a variety of pure, simulated, or intermittent sounds, making them highly versatile as sounding devices in electronic products.
  • Piezoelectric Buzzers: Utilizing piezoelectric effects to generate sound, these buzzers are often favored for their compact size, low power consumption, and clarity of tone.
  • Active and Passive Buzzers: Both types are available, with active buzzers containing an internal oscillation source for direct sound production, and passive buzzers requiring an external oscillation signal.
  • Electronic Buzzers and Magnetic Transducers: These components further broaden their offering for various audible signal applications.
• Speakers: FHD Electronic produces various types of speakers, including:
  • Micro Speakers: Compact and lightweight, ideal for small electronic devices where space is a premium.
  • Mylar Speakers: Known for their robust performance in challenging environments due to their Mylar cone material, offering resistance to moisture and temperature fluctuations.
  • OEM Speaker Manufacturing: They provide comprehensive OEM (Original Equipment Manufacturer) services, collaborating closely with businesses to design, develop, and manufacture custom speaker solutions that meet specific client specifications and exceed expectations, from concept to completion.
• Sensors: While specific types are not detailed, their offering of sensors suggests components designed to detect sound, vibration, or other physical phenomena that can be converted into electrical signals.
• Microphones: Components designed to convert sound waves into electrical signals, vital for voice control, audio recording, and communication functionalities in devices.
• Piezoelectric Transducers: Devices that convert electrical energy into mechanical energy (and vice-versa) using piezoelectric materials, often used in ultrasonic applications, sensing, and specialized sound generation.
• Alarms and Ultrasonic Devices: The company's R&D and production capabilities extend to these broader categories, indicating their ability to integrate their core components into functional modules.
