Front Side Top Industrial Design Specification
Purpose
Define a dimensioned industrial design baseline for enclosure and control proportions before detailed schematic and PCB implementation.
Overall Dimensions
- Width: 220 mm fixed target
- Height: 125 mm nominal target
- Depth: 95 mm nominal target
- Corner treatment: modest radius, visually soft but not rounded like a portable speaker
Front Proportions
- Front face width utilization should emphasize horizontal calmness
- Control band centered horizontally
- Knob outer diameter target: 28 mm to 36 mm
- Knob center positions target: approximately 45 mm to 60 mm in from each side depending on speaker layout
- Display centered between knobs
- Display visible window target: 62 mm x 22 mm baseline
Front Elevation Zones
- Left acoustic zone
- Left knob zone
- Center display zone
- Right knob zone
- Right acoustic zone
Top View Intent
- Clean uninterrupted top plane
- No top-facing controls in baseline concept
- Wood-look surface should read as furniture-like rather than gadget-like
- Internal antenna placement should be supported near top-rear or side-rear non-metallic regions
Side View Intent
- Slightly deeper rear body acceptable
- Front face may be inset by 2 mm to 4 mm from main cabinet shell
- Base may include a subtle plinth or foot reveal for visual lift
Front Panel Feature Targets
- Display glass/acrylic cover flush or slightly recessed
- Knob-to-display edge clearance target: minimum 14 mm visual breathing room
- Knob-to-side-wall clearance target: minimum 16 mm
- Grille margin to enclosure edges target: minimum 8 mm
Speaker Grille Proportions
- Symmetrical left/right grille fields preferred
- Each grille field baseline: 52 mm wide x 68 mm tall
- Grille fields may be rectangular with softened corners or circularly modulated within a rectangular quiet zone
Rear and Bottom Functional Allocation
- Rear panel: charging/power connector, optional line output or service port, ventilation strategy if needed
- Bottom: feet, fasteners, labeling, optional battery service seam only if needed
Materials and Finish Direction
- Exterior: wood veneer look or wood-grain polymer finish
- Front insert area: matte neutral contrast panel, likely warm gray, off-white, or charcoal depending brand direction
- Knobs: tactile matte finish, fine radial grip, restrained metallic or polymer cap
- Grille: perforated metal or acoustically transparent fabric backed by structural substrate
Ergonomic Targets
- Knobs usable from 0.5 m to 1.5 m viewing distance context
- Display readable at seated tabletop height
- Product should feel stable during one-handed knob rotation
Mechanical Constraints for EE
- Reserve clear antenna keep-out near enclosure edge
- Avoid placing battery directly behind antenna zone
- Reserve central front area for display module depth and connector strain relief
- Preserve acoustic volume left/right of PCB where possible
Open Decisions
- Final materials stack
- Exact driver size and count
- Battery capacity target vs enclosure depth tradeoff
- Need for rear passive radiator or venting
