Structural design features
1. Integrated lightweight structure of the cavity
The substrate is made of 6061 aluminum alloy solid material milled and formed, with an overall cavity structure and a wall thickness control of 1.2-2.5mm. It balances structural strength and lightweight, and is more resistant to drop and deformation compared to plastic shells;
2. Layered function limit inner cavity
Internally milling integrated limit steps, protrusions, battery compartment compartments, and circuit board positioning columns, without the need for additional plastic brackets, directly clamping PCBs, speakers, and lithium batteries; Reserve cable trays to prevent wire compression and wear.
Multi type integrated hole layout
1. Function openings: display screen window, speaker sound outlet, volume knob through-hole, 3.5mm audio interface, Type-C charging port; Make a C0.2 small chamfer on the edge of the hole to prevent scratching;
2. Tightening holes: Side/bottom M2/M2.5 threaded countersunk holes, built-in screw posts, no protruding screws on the surface of the shell, neat appearance;
3. Assembly positioning holes: Diagonal reference positioning holes ensure alignment of the upper and lower shells during assembly.
4. Appearance and human-machine design
All external edges and corners are rounded to R0.8~R2, with no sharp edges or corners when held;
Reserved sealing groove, can be equipped with silicone sealing ring to achieve basic dust and water resistance.
Characteristics of CNC machining technology
1. No mold threshold: direct aluminum block milling, small batch (1-500 units) without the need for die-casting molds, suitable for quick sampling of niche, retro, and customized radios;
2. Integrated milling molding: The inner and outer cavities, steps, and hole positions are completed in one CNC machining, with a dimensional tolerance of ± 0.02mm, and assembly accuracy far higher than injection molding/die casting;
3. Strong ability to implement complex and irregular shapes: Slopes, oblique angles, irregular surfaces, and irregular button slots can all be directly milled out, with high degree of freedom in shaping.
Application scenarios
1. High end portable retro radio (core scene)
Nostalgic retro desktop radio, portable FM shortwave player, metal aluminum shell enhances texture, aimed at audio enthusiasts and collectors, emphasizing exquisite touch and metal retro appearance.
2. Professional outdoor communication radio equipment
The multi-functional radio and intercom shell for field rescue and camping is made of aluminum alloy that is resistant to drops and corrosion, and has a hard anode that is suitable for outdoor environments such as rainwater and sandstorms.
4. Desktop HIFI radio all-in-one machine
Desktop small radio Bluetooth all-in-one machine, CNC aluminum shell can be matched with heat dissipation structure, taking into account the heat dissipation needs of radio and amplifier, and suppressing body heating.
5. Industrial grade explosion-proof sound receiving device
Specialized radio equipment for workshops and weak current rooms, with metal aluminum shells that are flame-retardant and anti-static, and no potential fire hazards caused by static electricity in plastic shells, suitable for industrial weak current environments.
