6mm Bidirectional Microphone Element for Headset Mics

Reliability Tests

• High Temperature Test: Microphone subjected to +80℃ for 100 hours, followed by 3 hours at room temperature.
• Low Temperature Test: Microphone subjected to -40℃ for 100 hours, followed by 3 hours at room temperature.
• Humidity & Heat Test: Microphone exposed to +55℃ and 85% relative humidity for 100 hours, followed by 3 hours at room temperature.
• Thermal Shocking Test: Microphone subjected to [+80℃ 0.5H → room temp 1H → -40℃ 0.5H → room temp 1H] for 10 cycles, then exposed to room temperature for 3 hours.
• Vibration Test: Microphone subjected to two hours of vibration in x, y, and z directions with frequencies of 10-55Hz and a 1.52mm amplitude.
• Drop Test: Microphone dropped 5 times from a height of 1.0 meter onto a slippery marble floor, without packaging, and still performs normally.
• Storage and Operating Temperature Range: Suitable for environments ranging from -35℃ to +60℃.
