[0029] As shown in the figure, a preferred embodiment of this utility model provides a vibration sound-generating circuit and a vibration sound-generating sphere, and the design and technical solution is as follows:

[0030] The first technical solution involves designing a vibration-generating sound circuit. The main structure of the vibration-generating sound circuit includes a main control module, an energy storage module, and a sound control module. The energy storage module and the sound control module are connected to the main control module. The energy storage module provides driving power to the main control module and the sound control module. The sound control module receives control signals from the main control module based on the motion state of the sphere, processes and converts them into sound information, and then emits sound.

[0031] The second technical solution involves designing a vibrating sound-generating sphere based on the principle and structure of a vibration-generating sound circuit. Applying the aforementioned principle, various spherical structures used in conventional motion are employed, with an air nozzle 2 installed on the sphere 1. The sphere is composed of a multi-layered composite structure, including at least an outer skin layer 101 and an inner liner 102. The technical solution includes a protective cavity structure within the inner liner of the sphere 1, housing an integrated circuit board 3, a power storage unit 5, a sound-generating unit 30, and a charging unit 4. The integrated modules on the integrated circuit board 3 include a main control module, a sound control module, and an energy storage module. The power storage unit 5, the sound-generating unit 30, and the charging unit 4 are connected to the integrated circuit board 3 via electrical wires. The power storage unit 5 can store electrical energy through the charging unit 4 and provide driving power to drive the sound-generating unit 30 to emit sound.

[0032] The sound-generating unit 30 can be attached to one of the integrated circuit board 3, the charging unit 4, and the energy storage unit 5, and is located at a symmetrical position in the same diameter direction as the air nozzle 2.

[0033] Furthermore, the integrated circuit board 3, energy storage unit 5, sound generation unit 30, and charging unit 4 can be dispersed and arranged in different protective cavities on the inner wall of the sphere 102, or integrated into the same protective cavity on the inner wall of the sphere. Alternatively, the integrated circuit board, energy storage unit, sound generation unit, and charging unit can be evenly and fixedly arranged in different positions on the inner wall of the inner wall of the sphere 102, or integrated into the inner wall of the inner wall of the sphere 102, or integrated into an embedded cavity on the inner wall of the inner wall of the sphere 102.

[0034] The charging unit 4 can be set separately in a protective cavity, and the position of the charging unit 4 is set in a position that is symmetrical to the air nozzle in the same diameter direction, so as to facilitate the identification of the charging direction.

[0035] A through-channel is provided on the inner liner 102 of the sphere, which connects to the protective cavity where the sound-generating unit is located. The sound emitted by the sound-generating unit can be dispersed outward through the through-channel. One or more sound-permeable holes are provided on the outer skin layer, which can facilitate the further outward dispersion of sound. Example

[0036] Example 1 provides a vibration sound-generating circuit according to the first technical solution. In actual operation, the design and implementation of the vibration sound-generating circuit shall be carried out in accordance with the specific technical solution. Figure 1 The circuit diagram shown illustrates the technical solution for the vibration-generating sound circuit:

[0037] It is mainly composed of a main control module, an energy storage module, and a sound control module. The energy storage module and the sound control module are both connected to the main control module. The energy storage module can provide driving power to the main control module and the sound control module. The main control module can send control signals according to the movement state of the sphere, and the sound control module receives the control signals from the main control module and emits sound.

[0038] Specifically, the main structure of the main control module consists of a main control chip U4 and a vibration switch S1. The vibration switch S1 is connected to the trigger switch connection pin 1 of the main control chip U4. The circuit of the main control chip U4 can be closed or opened through the vibration switch S1.

[0039] The main control chip U4 uses an SOT23-6 power switch chip, and the vibration switch S1 uses an SW SPST micro switch, which is normally open. The circuit of the main control chip U4 is in the open state. When the ball is in motion, the vibration switch S1 detects the vibration signal and closes the circuit. The circuit of the main control chip U4 is closed and turned on, and the main control module enters the working state. It then sends a control signal to drive the sound control module to work. The sound control module emits sound according to the control signal sent by the main control module.

[0040] The main structure of the energy storage module consists of a wireless charging chip U1, a wireless charging unit, and an energy storage unit. The wireless charging chip U1 connects the wireless charging unit and the energy storage unit, driving the wireless charging unit to store energy in the energy storage unit, and also providing power to the main control module and the sound control module. In actual operation, the wireless charging chip U1 uses a DFN6-2*2 power management chip, the energy storage unit uses a 3.7V rechargeable battery, and the wireless charging unit uses a wireless charging receiving coil L1.

[0041] The main structure of the sound control module consists of a sound chip and a sound-generating unit. The sound chip includes a first conversion chip U2 and a second conversion chip U3. The sound-generating unit is connected to the main control module sequentially via the first conversion chip U2 and the second conversion chip U3. Both the first conversion chip U2 and the second conversion chip U3 use SO8-1 chips. The sound-generating unit uses a miniature speaker LS1, which is connected to the output pin of the second conversion chip U3 via a speaker interface. The control signal output from the main control chip U4 is sequentially converted and amplified by the first conversion chip U2 and the second conversion chip U3 into sound information. Finally, the sound information is received and emitted by the miniature speaker LS1.

[0042] The sound-generating unit can be either a loudspeaker or a horn. Example

[0043] Example 2 provides a vibrating sound-generating sphere according to the second technical solution. It adopts the vibration sound-generating circuit principle of the first technical solution in Example 1, and implements the design of a vibrating sound-generating sphere according to the second technical solution. The specific structure adopts various spheres used in conventional sports in the prior art, such as... Figure 2 As shown, the sphere 1 has a conventional structure with an air nozzle 2. The sphere 1 can be composed of a multi-layered composite structure, with at least two layers: an outer skin layer 101 and an inner liner 102. A protective cavity structure is provided on the inner wall of the inner liner 102 of the sphere 1. An integrated circuit board 3, an energy storage unit 5, a sound generation unit 30, and a charging unit 4 are provided in the protective cavity. The integrated modules on the integrated circuit board 3 include a main control module for the vibration sound generation circuit, a sound control module, and an energy storage module. The energy storage unit 5, the sound generation unit 30, and the energy storage unit 4 are connected to the integrated circuit board 3 through electrical wires. The energy storage unit 5 can store electrical energy through the charging unit 4 and can provide driving power to drive the sound generation unit 30 to emit sound.

[0044] In the second embodiment, the integrated circuit board 3, the charging unit 4, the energy storage unit 5, the sound generating unit 30, and the air nozzle 2 are respectively set at the positions of the four quadrant points of the inner liner 102 of the sphere.

[0045] The air nozzle 2 is positioned at one of the four quadrants of the inner liner 102 of the sphere. An inner protective cavity is positioned at the other three quadrants of the inner liner 102, namely an integrated circuit protection cavity 103, a charging protection cavity 104, and a power storage protection cavity 105. The integrated circuit board 3, the charging unit 4, and the power storage unit 5 are respectively fixed inside the integrated circuit protection cavity 103, the charging protection cavity 104, and the power storage protection cavity 105. The sound-generating unit 30 can be attached to one of the integrated circuit board 3, the charging unit 4, or the power storage unit 5, positioned symmetrically along the same diameter as the air nozzle 2. Both the charging unit 4 and the power storage unit 5 are connected to the integrated circuit board via electrical wires. The power storage unit 5 provides driving power to the integrated circuit board, which detects whether the sphere is vibrating and emits sound based on the sphere's motion. The charging unit 4 charges and stores energy in the power storage unit 5.

[0046] In this example, the sound-generating unit 30 is attached to the bottom of the integrated circuit board 3 to form a sound-generating assembly. The integrated circuit protection cavity 103 is set at a symmetrical position with the air nozzle 2 in the same diameter direction, and the sound-generating assembly is fixedly encased in the integrated circuit protection cavity 103.

[0047] Specifically, the integrated circuit protection cavity 103 and the air nozzle 2 are arranged at two quadrant points along the first diameter direction of the inner liner 102 of the sphere. That is, the air nozzle 2 and the sound-generating component are arranged at two quadrant points along the first diameter direction of the sphere, which is vertical. The charging unit 4 and the energy storage unit 5 are arranged at two quadrant points along the second diameter direction of the inner wall of the sphere 1, which is horizontal. This achieves the first diameter direction being perpendicular to the second diameter direction. The charging unit 4 is connected to the integrated circuit board 3 via a first electrical wire 6, and the energy storage unit 5 is connected to the integrated circuit board 3 via a second electrical wire 7. Both the first electrical wire 6 and the second electrical wire 7 are tightly and reliably fixed to the inner wall of the inner liner 102 of the sphere.

[0048] Furthermore, a marking pattern can be set on the outer surface of the sphere 1 at the position corresponding to the charging unit 4 to facilitate identification of the sphere's charging location and make operation convenient. The marking pattern can directly use registered trademarks, sports activity logos, and other logos.

[0049] The charging unit 4 can adopt a wireless charging transmitting coil structure, or it can directly adopt the mature product structure of the charging interface in the existing technology.

[0050] When the charging unit 4 adopts a wireless charging transmitting coil structure, it can cooperate with an external wireless charging base equipped with a wireless charging transmitting coil to charge and store energy for the energy storage unit 5, maintaining the integrity of the sphere structure. The charging unit 4 can directly adopt the mature product structure of existing wireless charging receiving coils, such as those used in mobile phones or other smart home appliances. This allows it to be directly used with existing mature wireless charging bases, further improving the product's versatility. An external charging support ring can also be configured to stably support and rotate the sphere on the external wireless charging base for charging.

[0051] An external fixing ring accessory can also be configured to stably support and rotate the ball on the wireless charging dock for charging.

[0052] Energy storage unit 5 can be a conventional rechargeable battery.

[0053] Specifically, the sound-generating component, charging unit 4, and energy storage unit 5 can be glued to the integrated circuit protection cavity 103, charging protection cavity 104, and energy storage protection cavity 105 of the inner liner 102 of the sphere. The silicone adhesive has good flexibility, elasticity, and adhesion, effectively adhering to the inside or surface of the sphere, ensuring the connection strength and stability between the integrated circuit board 3, the sound-generating unit, the wireless charging receiving coil, the rechargeable battery, and the sphere, thereby reducing signal loss and interference. Specifically, openings can be made in the walls of the integrated circuit protection cavity 104, charging protection cavity 103, and energy storage protection cavity 105. After the sound-generating component, charging unit 4, and energy storage unit 5 are placed into the integrated circuit protection cavity 103, charging protection cavity 104, and energy storage protection cavity 105 respectively through the openings, they are then glued to the inner walls of the integrated circuit protection cavity 103, charging protection cavity 104, and energy storage protection cavity 105 of the inner liner 102 of the sphere using silicone adhesive. Organic silicone has good flexibility, elasticity and adhesion, which can effectively adhere to the surface of the inner liner of the sphere and the sound-generating component, charging unit 4 and energy storage unit 5, ensuring the connection strength and stability between the sound-generating component, charging unit 4 and energy storage unit 5 and the sphere, thereby reducing signal loss and interference.

[0054] The specific structural features of the sphere can be set according to the structural features of basketballs, footballs, volleyballs, rugby balls or other balls in the prior art. For example, at least two layers can be set. The three-layer structure is in the order of an inflatable inner layer and an outer protective layer from the inside out. The outer protective layer is the outer skin layer. The inflatable inner layer constitutes the inner bladder 102 of the sphere. All components in this utility model are fixedly set on the inner bladder 102 of the sphere.

[0055] The inner liner 102 of the sphere can be made of elastic materials such as rubber or PDMS (polydimethylsiloxane, also known as dimethyl silicone oil). Rubber and PDMS have good flexibility, tensile properties, wear resistance and environmental resistance, which can protect the integrated circuit 3, the wireless charging receiver coil and the rechargeable battery from physical and environmental damage that may be encountered during the movement of the sphere.

[0056] Alternatively, during the sphere manufacturing process, the integrated circuit board 3, the wireless charging receiver coil, and the rechargeable battery can be directly integrally formed and fixedly connected to the inner wall of the sphere's inner liner 102 at three of the four quadrant points, with the air nozzle positioned at the other quadrant point.

[0057] The air nozzle can be adapted to the conventional spherical structure technology.

[0058] The wireless charging receiver coil is made of pure copper, also known as red copper. Because pure copper has excellent ductility and conductivity, it can be rolled into a concave arc shape during operation to fit the concave arc inner surface of the sphere's inner liner 102. The specific fixing and connection methods are all conventional technical means, and this utility model does not involve any improvement to the fixing and connection technology.

[0059] The integrated circuit board adopts a PCB printed circuit board assembly printed according to the vibration sound generation circuit principle in the first technical solution of the above embodiment. In the vibration sound generation circuit, the miniature speaker LS1 and other components, except for the wireless charging receiving coil and the rechargeable battery, are all integrated on the PCBA printed circuit board. The four components are set on the inner wall of the sphere 1 at the positions corresponding to the four quadrant points, which can realize the balance and stability of the sphere and prevent the center from shifting. In the specific operation process, in order to prevent the center from shifting and ensure the balance and stability of the sphere, auxiliary counterweight structures can also be set on each component to further improve the balance and stability performance.

[0060] Furthermore, the sound-generating component is fixedly connected to the inner liner 102 of the sphere via an organic silicone connecting layer 201. A sound-permeable hole 23 is also provided in the middle of the organic silicone connecting layer 202. A through-channel 24 is also provided in the middle of the inner liner 102 corresponding to the position of the sound-generating component, which allows the sound emitted by the sound-generating unit 30 to be emitted outward. The through-channel 24 is connected to the protective cavity where the sound-generating unit is located. Multiple amplification holes 25 are also provided on the outer skin layer 101. This ensures that the sound emitted by the vibrating sound-generating component can be emitted outward, thus ensuring the sound generation effect.

[0061] like Figure 3As shown, the charging unit 4 is connected to the integrated circuit board 3 via the first electrical wire 6, and the energy storage unit 5 is connected to the integrated circuit board 3 via the second electrical wire 7. The first electrical wire 6 and the second electrical wire 7 are both tightly attached and fixedly connected to the inner wall of the sphere inner liner 102, which is stable and reliable.

[0062] The first electrical wire 6 and the second electrical wire 7 can also be fixedly attached to the inner wall of the sphere inner liner 102 with silicone. The two ends of the first electrical wire 6 and the second electrical wire 7 can pass through the wall of the protective cavity and be connected to the corresponding components respectively. The specific operation can be carried out in accordance with conventional technical means in this field. Example

Figure 2 As shown, the structure consists of three layers: an outer skin 101, an inner bladder 102, and a middle shaping 100. The middle shaping 100 is made of a porous textile, which also facilitates the outward diffusion of sound. Example

First, the integrated circuit board 3, energy storage unit 5, sound generation unit 30, and charging unit 4 are all bonded together to form an integrated sound generation component. This integrated sound generation component is then fixedly attached to the inner wall of the second inner sphere 10 through a second silicone adhesive layer 202 in a fully encapsulating manner, thus forming an integrated protective cavity. Simultaneously, multiple sound holes 25 can also serve as markers for wireless charging. Example

The textile protective layer 21 itself is a porous sound-permeable material. The textile protective layer 21 is fixedly bonded between the second outer skin layer 10 and the inner liner 10 of the second sphere. Example

[0066] Example 6 provides another type of vibrating sound-generating sphere according to the second technical solution. It adopts the vibrating sound-generating circuit principle of the first technical solution in Example 1, and, based on the vibrating sound-generating sphere structure provided in Example 2, uses an alternative layout technical solution, such as... Figure 5 As shown, the sound-generating unit 30 is attached to the lower part of the integrated circuit board 3 to form a sound-generating assembly. The integrated circuit protection cavity is set at a symmetrical position with the energy storage unit 5 in the same diameter direction. The sound-generating assembly is fixedly encased in the integrated circuit protection cavity 103. The sound-generating assembly, charging unit 4, and energy storage unit 5 are fixedly glued to the integrated circuit protection cavity, charging protection cavity, and energy storage protection cavity of the inner liner 102 of the sphere.

[0067] The charging protection cavity is located symmetrically to the air nozzle 2 in the same diameter direction. In other words, the charging unit 4 is located in the protection cavity and symmetrically to the air nozzle 2 in the same diameter direction.

[0068] Specifically, a charging protection cavity is set at two quadrant points along the first diameter direction within the inner liner 102 of the sphere; that is, the air nozzle 2 and the charging protection cavity are set at two quadrant points along the first diameter direction of the sphere, where the first diameter direction is vertical. The integrated circuit protection cavity 103 and the energy storage unit 5 are set at two quadrant points along the second diameter direction on the inner wall of the sphere 1, where the second diameter direction is horizontal. This achieves the first diameter direction being perpendicular to the second diameter direction. Figure 6 As shown, the charging unit 4 is connected to the integrated circuit board 3 via the third electrical wire 16, and the energy storage unit 5 is connected to the integrated circuit board 3 via the fourth electrical wire 17. The third electrical wire 16 and the fourth electrical wire 17 are both tightly attached and fixedly connected to the inner wall of the sphere inner liner 102, which is stable and reliable.

[0069] The third electrical wire 16 and the fourth electrical wire 17 can also be fixedly attached to the inner wall of the sphere inner liner 102 using silicone adhesive. The two ends of the third electrical wire 16 and the fourth electrical wire 17 can pass through the wall of the protective cavity and be connected to the corresponding components. The specific operation can be carried out in accordance with conventional technical means in this field. Example

For example, at least three layers can be provided. The three layers are, in order from the inside out, an inflatable inner layer, a shaping middle layer, and an outer protective layer. The inflatable inner layer constitutes the inner bladder. All components in this invention are fixedly installed in the inner surface protective cavity of the inner bladder.
