Technical details and manufacturing context for Array Housing

Definition
Array Housing is the structural component of an Active Noise Cancellation (ANC) Microphone Array that provides physical protection, mechanical stability, and environmental shielding for the sensitive microphone elements. It ensures precise positioning of microphones for optimal beamforming and noise cancellation performance while protecting against dust, moisture, and physical damage.
Working Principle
The housing maintains fixed geometric relationships between microphone elements, enabling accurate phase and amplitude measurements for spatial audio processing. Its acoustic properties (such as port design and material density) influence sound wave reception while providing mechanical isolation from vibrations.
Common Materials
Aluminum alloy, ABS plastic, Acoustic foam
Technical Parameters
  • Overall dimensions and mounting hole positions (mm) Standard Spec
Components / BOM
  • Mounting Bracket
    Provides attachment points for securing the array to surfaces
    Material: Stainless steel
  • Acoustic Mesh
    Filters dust while allowing sound waves to pass through
    Material: Polyester fabric
  • Vibration Dampers
    Isolates microphones from mechanical vibrations
    Material: Silicone rubber
Engineering Reasoning
0-120 dB SPL (sound pressure level) at 20-20000 Hz frequency range
Structural deformation exceeding 0.5 mm at any mounting point or resonant frequency matching 1500±50 Hz
Design Rationale: Acoustic-structural coupling causing resonant amplification at natural frequency, leading to fatigue failure via cyclic stress concentration at mounting interfaces
Risk Mitigation (FMEA)
Trigger Thermal expansion mismatch between aluminum housing (α=23.1×10⁻⁶/K) and PCB substrate (α=15×10⁻⁶/K)
Mode: Mounting screw shear failure due to differential expansion stresses exceeding 250 MPa yield strength
Strategy: Implement bimetallic compensation washers with controlled thermal expansion coefficient gradient of 18-22×10⁻⁶/K
Trigger Acoustic pressure wavefront impingement at 45°±5° incidence angle
Mode: Helmholtz resonance excitation within cavity volume of 8.2 cm³, causing 12 dB signal distortion
Strategy: Integrate quarter-wavelength acoustic dampers tuned to 1500 Hz with polyurethane foam (flow resistivity 10000 Rayls/m)
