Hollow Toy Ball with Integrated Music Player and Bell

The problem

Manufacturing small, feature-rich toys often involves labor-intensive assembly processes. Gluing electronic components into plastic shells creates waste and makes repairs impossible. Screws add weight and require tools during final packaging. Furthermore, combining multiple sensory features—such as sound, light, and physical movement—into a compact, durable form factor is challenging. Traditional designs may lack structural integrity when dropped, leading to broken internal components. There is a need for a toy design that is easy to assemble, cost-effective to produce, and robust enough for active play while integrating multiple functions.

The solution

The patent proposes a hollow toy ball constructed from modular parts that lock together mechanically. The core innovation lies in the fixed connecting block, which serves as both a structural anchor and an electronic housing.

1. Structural Framework: The ball is formed by an upper spherical cap and a lower spherical cap. These caps are connected by cross bars and vertical rods.
2. Central Hub: A fixed connecting block sits at the center. It consists of an upper cover body and a lower cover body that join via a bayonet mechanism. This creates a control room inside.
3. Electronics Integration: Inside the control room, a power supply device and a music playing device controller are mounted at the bottom. A miniature music playing device is fixed at the top. A micro-speaker is placed on the upper end of the central block.
4. External Features: The vertical rods can house LED lights. An upper spherical cap features a wire lifting block with a threading hole for a portable line. A small bell hangs from the top of the upper cap, positioned inside the hollow structure to ring when the ball moves.

Who it is for

• Toy Manufacturers: Companies looking to reduce assembly time and costs by eliminating adhesives and fasteners.
• Educational Toy Brands: Designers creating multi-sensory toys that combine auditory (music/bell) and visual (LED) stimuli for child development.
• Promotional Gift Suppliers: Businesses needing durable, customizable novelty items with embedded electronics for branding or events.
• Amazon Sellers: Entrepreneurs seeking a distinctive product that ships as modular parts and offers several sensory features in one item.

How it works

The main parts

The toy relies on mechanical interlocks rather than chemical bonds. The numbering corresponds to the patent drawings.

Operating steps

1. Assemble the Core: The upper cover body (13) and lower cover body (15) are snapped together using the bayonet lock. This encloses the control room (17).
2. Install Electronics: Before closing the core, the power supply (19), controller (21), and music player (18) are fixed inside. Wires (20) connect these components. The microspeaker (12) is mounted on the exterior of the upper cover.
3. Attach Structure: The cross bars (6) and vertical rods (10) are inserted into the connecting holes (14) of the central block. They are secured by the buckles (16).
4. Close the Shell: The upper spherical cap (1) and lower spherical cap (11) are attached to the ends of the rods and connected via the connecting ring (7).
5. Add Accessories: The small bell (5) is hung from the top interior. The portable line (4) is threaded through the lifting block (2).
6. Activate: When powered, the LED lights (9) illuminate the rods, and the music player controller (21) drives the music player (18) to output sound through the microspeaker (12). Movement causes the bell (5) to ring.

Applications

Infant Development Toys

Parents use the ball for sensory stimulation. The combination of LED lights, music, and the physical rattle of the bell helps infants track movement and associate cause-and-effect relationships. The hollow design allows babies to see through the ball, enhancing visual exploration.

Portable Entertainment

The inclusion of a portable line (4) allows the toy to be carried easily or hung from strollers and car seats. Hung within reach, it keeps the child engaged with its audio-visual features during travel.

Educational Classroom Tools

Teachers use the ball in early childhood education settings. The distinct sounds and lights can be used for attention-getting exercises or counting games.

Promotional Novelty Items

Brands can specify outer shell colors and audio content. The modular design allows electronic components to be changed for different campaigns without re-tooling the shell molds. It serves as a memorable, functional giveaway item.

Where it is less suitable

• Outdoor Rough Play: While sturdy, the hollow plastic structure may crack if subjected to extreme impacts or heavy adult weights. It is designed for indoor or supervised outdoor play.
• Water Environments: The patent does not specify waterproofing for the electronic compartment. Submerging the toy could damage the battery and circuitry.
• Complex Gaming Needs: This is a simple interactive toy. It lacks sensors for motion-based gaming or app connectivity, so it is not suitable for advanced digital interaction requirements.
