His article provides a technical and manufacturing-oriented overview of a portable device integrating a Bluetooth speaker with a projection function. Key features include an 1800mAh battery, Type-C charging, an independent-cavity speaker (iron shell, 4Ω 3W), a 2–3 meter adjustable-focus projection range, and full media control buttons. The product supports custom exterior colors, with a minimum order quantity (MOQ) of 1,000 units.
1. Product Positioning & Application Scenarios
This product is positioned as a portable multimedia entertainment terminal, suitable for the following scenarios:
Outdoor camping / travel - music and video playback
Children's stories / animated projection
Small meetings or training - auxiliary presentation display
Promotional gifts, branded merchandise, or custom electronic giveaways
Its core differentiation lies in the physical separation of audio quality and projection function, avoiding simple feature stacking.
2. Exterior Customization: Two-Color Collocation, Customer-Defined
Color strategy: Fully customizable per customer requirements, with a recommended two-color collocation to enhance visual identity and brand recognition.
Process compatibility: The housing supports standard painting, in-mold injection, or film coating, suitable for silk-screen logos or graphics.
Order requirement: Custom color orders must meet the MOQ of 1,000 units; small-batch multi-color validation is available.
3. Power & Charging System
| Item | Specification |
|---|---|
| Battery capacity | 1800 mAh |
| Continuous playback | Approx. 8 hours (Bluetooth audio mode) |
| Charging time | Approx. 2 hours |
| Charging port | Type-C |
| Included cable | 50 cm |
This power solution balances size and endurance, supporting a full day of moderate use. The Type-C port improves compatibility with mainstream charging devices.
4. Acoustic System: Independent Cavity + Iron Shell Speaker
Speaker specification: 4Ω 3W, iron shell construction
Cavity design: Independent cavity, physically isolated from the projection optical module
Benefits:
Reduces vibration interference from the projection unit
Improves mid-to-high frequency clarity
Lowers cavity resonance distortion
Compared to common all-in-one structures, the independent cavity represents a significant acoustic upgrade, ideal for portable scenarios where sound quality matters.
5. Projection System
Projection distance: 2–3 meters
Focus method: Manual adjustment knob
Operating environment: Wall or screen projection in low-light or dark conditions
The projection module is designed for basic usability, low power consumption, and ease of integration. It does not target high brightness but includes adjustable focus for indoor small-area or nighttime outdoor use.
