After finalizing the design, the manufacturer will proceed with the sample production.
This is a crucial step, as it allows you to evaluate the actual product before placing a bulk order.
The sample production process typically involves:
Selecting Materials:
The manufacturer will choose the appropriate materials based on your specifications.
The portable speaker manufacturing materials include casings, speaker drivers, amplifiers, batteries, circuit boards, ports, antennas, buttons, switches and wires, etc.
Assembly:
The sample speakers are assembled according to the agreed-upon design and technical specifications.
There are more than 100 processes in speaker production, including assembly of accessories (drive unit, crossover, MIC board welding), shell assembly, installation of drivers, etc. into the box, and circuit board connection.
Testing:
The sample undergoes various tests to ensure it meets quality standards and functions as expected.
There are 11-19 test items for speakers, including:
Audio Performance Test
Frequency response, sensitivity, impedance, total harmonic distortion (THD), signal-to-noise ratio (SNR), stereo separation, directivity
Function Test
Power output, battery life, Bluetooth connectivity
Other features (such as voice assistant, touch control, waterproof function, etc.)
Safety Test
Electrical safety, EMC testing, thermal testing, mechanical safety
Other Tests
Durability test, waterproof test, aesthetic test
