Description
Technical Field
[0001] This invention relates to the field of racket sports equipment technology, specifically to a sound-generating racket, such as a table tennis racket or a Peak racket. Background Technology
[0002] Chinese Patent No. CN106730701A discloses a light-emitting and sound-emitting Peak racket and its system. The Peak racket comprises a racket body and a handle. The racket body includes a face plate, a back plate, and a filler plate sandwiched between the face plate and the back plate. It also includes a frame surrounding the layered plate formed by the face plate, back plate, and filler plate. An LED light strip is tightly embedded outside the frame and connected to a light-emitting and sound-emitting circuit board embedded in the handle. The light-emitting and sound-emitting circuit board includes a main control unit, a sound control unit, a power supply unit, and a light-emitting unit to which the LED light strip belongs. The main control unit includes a main control chip and LED indicator lights. The sound control unit includes a speaker. The power supply unit includes a rechargeable battery, a charging interface, and a push-button switch. Implementing the light-emitting and sound-emitting Peak racket and its system provided by this invention enhances the functionality of the Peak racket in terms of light emission and sound emission, organically combining Peak sport and entertainment.
[0003] The aforementioned existing technical solutions rely on sound generation to enhance the enjoyment of the sport. However, these solutions cannot control sound generation through the force of the swing; in other words, sound is only generated when the athlete swings the racket with a certain force. Furthermore, existing solutions involve adding various electronic components inside the racket, which increases costs. Additionally, the high frequency of racket use inevitably leads to drops or impacts, easily damaging the internal electronic components and thus reducing practicality.
[0004] In summary, while existing technologies may include similar sound-producing rackets, they only enhance the enjoyment of the sport and fail to provide feedback or cues from the sound output. This results in a lack of reference for strength training. Therefore, a sound-producing racket is proposed to address the aforementioned issues. Summary of the Invention

[0008] Preferably, the sound-generating component includes a insert with two air inlets. A whistle is provided on the side of the air inlets. When the racket is swung, the airflow generated on the surface enters the interior of the whistle through the air inlets. The whistle can produce a sound of different decibel levels depending on the pressure of the incoming air.
[0009] Preferably, the sound-generating component includes a vibrating plate, and an air intake channel is provided on the racket body or handle. The vibrating plate is disposed in the air intake channel. When the racket body is swung, the airflow generated passes through the air intake channel and vibrates the vibrating plate, thereby generating a prompting sound.
[0010] Preferably, a limiting member is provided inside the air inlet; the limiting member includes a pressure plate, which slides inside the air inlet, and a pressure spring is connected to the side of the pressure plate. The pressure spring is located inside the air inlet, and a through groove is provided inside the air inlet.
[0011] Preferably, the sheath and the handle are connected by a snap-fit connector, which includes a V-shaped spring. The handle has a slot inside, and the V-shaped spring is located inside the slot. One end of the V-shaped spring is connected to the handle, and the other end is connected to an insert. The sheath has an insert plate inside, and the insert plate has a slot. The insert is snapped into the slot. There are two sets of snap-fit connectors, two in each set, and the two sets of snap-fit connectors are symmetrically distributed along the center lines of the upper and lower plates. The handle has a slot, and the insert plate is inserted into the slot.
[0012] Preferably, the surface of the sheath has multiple sets of air holes, and the surface of the sheath is provided with mating textures that fit the curved surface of the user's finger.

[0014] Preferably, there are two air grooves and air inlets, and the air grooves are closed near the tail of the handle.
[0015] Preferably, the airflow assembly further includes an air groove on the handle, wherein the end face of the air groove near the upper or lower plate is closed, the end face of the air groove near the tail of the handle is open, and the air groove is in communication with another set of air holes. Preferably, the slot is provided with a reinforcing strip inside, and the length of the reinforcing strip is in a ratio of 1:5 to the length of the slot.
[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a sound-generating racket, which has the following beneficial effects: 1. The sound-generating racket of this invention, through its specially designed sound-generating component, generates airflow during a swing. This airflow passes through the sound-generating component, causing it to produce sound, providing the athlete with better feedback on the shot and enhancing their enjoyment of the game. The sound-generating racket also has a unique feature: when athletes use the racket and hear the sound, they can identify the racket brand, which is beneficial for brand promotion. Furthermore, the volume of the sound is determined by the force of the swing. Users or trainees can use this type of racket to control the swing pressure based on the volume of the sound emitted by the sound-generating component, thus achieving force control.
[0017] 2. The racket that produces sound, through the setting of limiting components, can reach a certain force during the athlete's swing in order to drive the movement of the pressure plate, thereby controlling the airflow from the slot into the whistle to generate sound. This controls the triggering conditions for sound generation, thus producing a more comfortable feedback effect for the athlete's swing.
[0018] 3. This sound-generating racket, through its two air channels, controls the airflow generated during hitting or swinging motions, creating two special air channels that directly act on the handle and cover. The resulting airflow also acts in the opposite direction on the user's hand, creating airflow in the palm of the hand. This effectively controls the rapid evaporation of sweat, preventing sweat accumulation that could lead to a poor grip or even the racket slipping out of the hand. Therefore, the two special airflow channels effectively improve the stability of the user's racket grip.
[0019] 4. The racket that produces sound can be used with a protective cover through a snap-fit mechanism, allowing for quick and easy detachment of the cover and handle. This also allows for rapid replacement of the protective cover as dirt accumulates over time, eliminating the need for repeated cleaning and enabling users or athletes to quickly begin training.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] One embodiment of the present invention is as follows: Please see Figures 1-10A sound-generating racket includes a racket body, which comprises a racket frame and a handle. A sound-generating component is provided on the racket body, capable of producing a prompt sound when the force of the swing reaches a preset force, indicating the user's swing force. The sound-generating component is located on the handle or racket frame. The racket frame includes an upper plate 1 and a lower plate 2, with a full-circle rubber ring along the edges of the upper plate 1 and lower plate 2, connected by adhesive. The handle includes a handle 5, with a protective sleeve 3 fitted onto the handle 5, connecting the sleeve 3 to the handle 5, and the handle 5 to the upper plate 1 and lower plate 2. The sound-generating component includes an insert 41 with two air inlets 44. A whistle 8 is provided on the side of the air inlets 44. During a swing, the airflow generated on the surface of the racket enters the whistle 8 through the air inlets 44, and the whistle 8 can produce a sound of different decibel levels depending on the air pressure. The whistle 8, when used with the racket, generates airflow during the swing motion. This airflow passes through the whistle 8, producing sound. The volume of the sound is determined by the swing force. Therefore, users or trainees can control the swing pressure based on the volume of the whistle, thus controlling the force and developing muscle memory for effective training. The air intake 44 has a limiting component inside; this limiting component includes a pressure plate 45 that slides inside the air intake 44. A pressure spring 46 is connected to the side of the pressure plate 45 and is located inside the air intake 44. A through groove 47 is provided inside the air intake 44. The limiting component is designed to restrict the triggering state of the sound-generating component. When the racket is swung, the airflow generated enters through the air inlet 44. Without the limiting component, the airflow action would produce sound on the whistle 8, which could easily have a negative impact on the athlete if it lasted too long. Therefore, the limiting component directly restricts the conditions for sound generation. After the airflow generated by the swing enters through the air inlet 44, if the airflow is small, that is, the swing force is small, the airflow is blocked by the pressure spring 46 when it pushes the pressure plate 45. When the airflow reaches a certain level, the airflow pressure will push the pressure plate 45 to slide in the air inlet. After the pressure plate 45 slides a certain distance, it enters the slot 47. At this time, the airflow will pass through the slot 47 and then flow out from the tail of the air inlet 44 into the interior of the whistle 8. Finally, the whistle 8 produces sound feedback to the athlete. Therefore, if the airflow does not control the pressure plate 45 to move to the slot 47, the airflow cannot pass through the air inlet 44, and the whistle 8 cannot produce sound, thus automatically limiting the triggering pressure for sound production.The entire limiting component can also be replaced with an electronic sensor. The electronic sensor is located inside the air intake 44. It will trigger the sound when the electronic sensor senses a certain air pressure value, and it can also control the pressure during the sound production process. However, the electronic sensor is an electronic component and cannot withstand a large degree of impact. Therefore, two sound-producing limiting components are used to provide users with a reference for selection.
[0024] Another embodiment of the present invention is as follows: Please see Figures 1-11 A sound-generating racket includes a racket body, the racket body comprising a racket body and a handle portion; The racket body is equipped with a sound-generating component, which can produce a prompting sound when the force of the swing reaches a preset level, providing feedback to the athlete. The sound-generating component is located on the handle or racket body; the racket body includes an upper plate 1 and a lower plate 2, with a full circle of rubber rings around the edges of the upper plate 1 and lower plate 2, connected by adhesive. The handle includes a handle 5, with a protective sleeve 3 fitted onto the handle 5, which is connected to the handle 5. The handle 5 is connected to the upper plate 1 and lower plate 2. The sound-generating component includes a vibrating plate 9. An air intake channel is provided on the racket body or handle 5, and the vibrating plate 9 is located within the air intake channel. When the racket body swings, the airflow passes through the air intake channel, vibrating the vibrating plate 9, which generates the prompting sound. This embodiment does not use a whistle to generate a sound, but rather uses the vibration of the vibrating plate 9 when the airflow blows on it to generate a prompting sound. This air intake channel can be located at the handle 5 or on the racket body. The "buzzing" sound generated by the vibrating plate 9 prompts the user's swing force. Therefore, the vibration sound of the vibrating plate 9 can also provide the athlete with both audible and slight vibration feedback. By using the sound and tactile vibration, dual-frequency hitting feedback is generated.
[0025] Another embodiment of the present invention is as follows: Please see Figures 1-6A sound-generating racket includes an upper blade 1 and a lower blade 2. A handle 5 is connected to both the upper blade 1 and the lower blade 2. A protective sleeve 3 is fitted onto the handle 5, and the protective sleeve 3 is connected to the handle 5 via a snap-fit component 4. The snap-fit component 4 includes a V-shaped spring 42. A slot is provided inside the handle 5, and the V-shaped spring 42 is located inside the slot. One end of the V-shaped spring 42 is connected to the handle 5, and the other end is connected to an insert 41. An insert plate 32 is provided inside the protective sleeve 3, and a slot 34 is provided on the insert plate 32. The insert 41 is snapped into the slot 34. At a corresponding position on the inner side of the protective sleeve 3, an integrally formed or fixedly connected insert plate 32 is provided. This insert plate 32 can be inserted into a pre-set slot 6 on the handle 5. At least one slot 34 is provided on the insert plate 32, and the shape of the slot 34 matches the end shape of the insert 41, typically a rectangular or trapezoidal notch. When the protective sleeve 3 is installed onto the handle 5, the insert plate 32 is inserted into the slot 6. During insertion, the insert piece 41, under the elastic support of the V-shaped spring piece 42, can elastically deform under external force. Once the insert plate 32 is pushed to the predetermined position, the insert piece 41 automatically snaps into the slot 34 under the action of elasticity, thereby locking the protective sleeve 3 and the handle 5. For disassembly, the user can press or move the insert piece 41 to disengage it from the slot 34, thus easily removing the protective sleeve 3 from the handle 5 for quick replacement or cleaning.
[0026] In this embodiment, two sets of snap-fit components 4 are provided, with two components in each set. The two sets of snap-fit components 4 are symmetrically distributed along the center lines of the upper plate 1 and the lower plate 2. The handle 5 has a slot 6, and the insert plate 32 is inserted into the slot 6. The snap-fit components 4 are arranged in a symmetrical multi-set manner to enhance the balance and overall stability of the connection between the sleeve 3 and the handle 5. Specifically, there are two sets, each containing two snap-fit components 4, which are symmetrically distributed about the center lines of the upper plate 1 and the lower plate 2 of the racket. This symmetrical layout allows the sleeve 3 to be evenly distributed to both sides of the handle when subjected to gripping or torsional forces, avoiding loosening of the connection or tilting of the sleeve 3 due to force on one side. To achieve accurate docking and fixation between the sleeve 3 and the handle 5, at least one slot 6 is provided longitudinally on the surface of the handle 5. The shape of the slot 6 matches the contour of the insert plate 32 on the inner side of the sleeve 3, and is usually a long strip groove. Its length and width are slightly larger than the size of the insert plate 32 so that the insert plate 32 can be smoothly inserted and maintain a moderate gap, facilitating installation and disassembly. The position of slot 6 corresponds to the aforementioned symmetrically distributed snap-fit pieces 4, ensuring that when the insert plate 32 is fully inserted into slot 6, its slot 34 can precisely align with the insert pieces 41 of each snap-fit piece 4, achieving multi-point synchronous engagement. This structure, through the cooperation of symmetrically distributed multi-point snap-fit and guide slot 6, not only enables quick assembly and disassembly of the sheath 3, but also significantly improves the structural strength and torsional resistance after connection, ensuring that the sheath 3 does not wobble or shift during use, providing users with a stable and reliable grip experience.
[0027] Furthermore, the surface of the sleeve 3 has multiple sets of air holes 33, and the surface of the sleeve 3 is provided with matching textures 31, which conform to the curvature of the user's fingers. The surface structure of the sleeve 3 is ergonomically and functionally designed to improve grip comfort, anti-slip performance, and breathability. Specifically, the outer surface of the sleeve 3 has multiple sets of air holes 33, which are usually arranged in an array or according to the pressure distribution area of the palm. The air holes 33 penetrate the wall thickness of the sleeve 3, forming a direct airflow channel between the grip area and the external environment. The surface of the sleeve 3 is molded or processed with matching textures 31. These matching textures 31 are not simple decorations or general anti-slip textures, but are specifically designed according to the physiological curvature and pressure distribution of the fingers, finger roots, and palm areas when a typical user holds the racket. Its texture pattern can be expressed as a series of micro-convex ridges that conform to the curve of the fingertip, a transition area that adapts to the concavity between the fingers, and a curved texture that conforms to the raised part of the palm. The depth, width, and spacing of the texture have been carefully considered to provide a significant contact area when the user grips the racket, increasing static friction while avoiding discomfort or cleaning difficulties caused by excessively deep or dense textures. Multiple sets of air holes 33 work synergistically with the matching texture 31 that conforms to the curve of the fingers: the air holes 33 promote airflow during swings or air movement, accelerating the evaporation of hand sweat and keeping the grip area dry; while the matching texture 31 ensures a stable and comfortable grip, distributing hand pressure and reducing fatigue during prolonged training. Together, they optimize the grip experience and control performance of the racket during intense or prolonged use.
[0028] Another embodiment of the present invention is as follows: Please see Figure 5 - Figure 7The handle 5 has a second air groove 53 on its surface, and an air inlet 44 on the insert 41. The air inlet 44 and the second air groove 53 are on the same axis, and the air hole 33 is connected to the second air groove 53. A coordinated airflow channel structure is provided between the handle 5 and the snap-fit part 4 to guide airflow during the swing and achieve active ventilation and sweat-wicking function. On the surface of the handle 5, the second air groove 53 is provided along its length or in a specific functional area. The second air groove 53 is a long groove recessed into the handle body, and its cross-sectional shape can be arc-shaped, rectangular, or other streamlined, with the purpose of forming a low-resistance airflow channel. On the insert 41 of the snap-fit part 4, the air inlet 44 is precisely provided at the position corresponding to the second air groove 53. The axis of the air inlet 44 is consistent with the extension direction or center line of the second air groove 53, ensuring that when the insert 41 is assembled in place, the air inlet 44 and the second air groove 53 are accurately aligned and connected in space. The air inlet 44 serves as a crucial entry point for external airflow into the internal flow channel of the handle. A portion of the multiple sets of air holes 33 on the surface of the sleeve 3, typically located near a specific area of the handle, communicates with the air groove 53 on the handle surface via the assembly interface between the sleeve 3 and the handle 5. Specifically, when the sleeve 3 is fitted onto the handle 5 and installed in place, its inner side fits snugly against the handle surface, and the outlet ends of some of the air holes 33 precisely cover or align with a section of the air groove 53, thus forming a continuous air passage between the air holes 33 and the air groove 53. When the user swings the racket forward, the racket moves against the wind, and external air enters through the air inlet 44 on the insert 41 under pressure, then flows into the air groove 53 on the handle surface aligned with it. The airflow moves forward along the air groove 53 towards the racket head and exits through the portion of the air hole 33 connected to the air groove 53, directly blowing onto the corresponding area of the user's hand, such as the palm or the base of the fingers. This process effectively utilizes the relative airflow generated during the swing, achieving directional airflow to the grip area, accelerating sweat evaporation, thereby keeping the hands dry and enhancing grip stability and comfort. In this embodiment, the air inlet 44 is oriented parallel to the racket, but it can also be perpendicular to the racket body (e.g., Figure 9 As shown), the specific selection can be set according to the user's swing habits. For example, some users swing in a "flicking" manner, with the racket tilted, so the air intake 44 is horizontal, allowing for a larger airflow. If some users are in a "horizontal hitting" state, they can choose a racket with the air intake 44 perpendicular to the racket body.
[0029] Optionally, the racket may include multiple air inlets that are both perpendicular to and parallel to the racket; this application does not impose any restrictions.
[0030] In this embodiment, two air grooves 53 and two air inlets 44 are provided, and the air groove 53 near the tail of the handle 5 has a closed structure. The handle 5 also has an air groove 52, which has a closed structure near the end face of the upper plate 1 or lower plate 2, and a connected structure near the tail of the handle 5, communicating with another set of air holes 33. The tail of the handle 5 has a large bevel 51, and the insert 41 has a guide groove 43. Two air grooves 53 and two corresponding air inlets 44 are provided, symmetrically or staggeredly distributed along the length of the handle 5 to expand the air intake cross-section and airflow coverage. The design of the air groove 53 is directional: its end near the tail of the handle 5, i.e., the grip end, has a closed structure. This closed end prevents airflow from directly entering or escaping from the tail of the handle, forcing airflow to enter only through the air inlet 44 located on the front or side of the handle during the forward swing. The airflow then flows forward along the second air groove 53 towards the racket head, and finally exits through the set of air holes 33 connected to the second air groove 53, directly blowing onto the front area of the palm. This unidirectional flow channel design optimizes the "pumping" efficiency during the forward swing. Parallel to the second air groove 53, the handle 5 also has a first air groove 52. Its airflow direction is designed opposite to the second air groove 53: the end of the first air groove 52 near the upper plate 1 or lower plate 2, i.e., the connection end near the racket head, is closed, preventing airflow towards the racket head; while its end near the tail of the handle 5 is open, directly communicating with the tail area of the handle or the environment. The first air groove 52 is connected to another set of air holes 33 on the surface of the sheath 3. This structure is specifically designed to capture airflow during the follow-through or backswing motion. To enhance airflow capture efficiency during the follow-through, the handle 5 has a large angled section 51 at its tail. This angled section 51 forms a significant windward slope or guide surface, effectively "catching" air as the racket moves backward, guiding the airflow more smoothly into the opening area at the tail of the handle, thus providing ample airflow to the air groove 52. During the forward swing: airflow mainly enters through the two air inlets 44, flows forward along the closed tail of the two air grooves 53, and exits through the corresponding air holes 33, cooling the front of the palm. During the follow-through / backswing: the large angled section 51 at the tail of the handle captures airflow, causing it to enter the racket head from the connecting end of the air groove 52, flow forward along the air groove 52, and exit through another set of air holes 33, cooling the corresponding area of the palm.
[0031] In addition, the sound-generating component includes a whistle 8, which is located at the air inlet of the air inlet 44. The whistle 8 can generate sounds of different decibel levels depending on the pressure of the incoming air. In actual training, it is necessary to control the overall swing force of the racket. Traditional rackets rely solely on the user's experience to judge and control the swing force, which can easily lead to muscle memory and imbalances in force judgment during training and actual matches. This sound-generating component can provide trainees with certain prompts during training. When the racket is swung, its structure resembles a blade, and the airflow enters through the air inlet 44, generating the sound of the whistle 8. The principle of the whistle 8 is that the airflow directly impacts the edge of the cavity or a small ball (like a pea whistle). The rolling of the ball disrupts the airflow, producing a vibrato. The stronger the airflow, the louder the sound, and the stronger the airflow, the greater the swing force. Therefore, trainees can judge the swing force based on the sound of the whistle 8, adjusting the force before the racket contacts the ball. It also provides a certain degree of force reference during training, indicating where and at what angle the ball lands and how much force to use when hitting the ball.
[0032] Furthermore, the edges of the upper blade 1 and the lower blade 2 are fitted with a full-circle rubber ring, and the upper blade 1 and the lower blade 2 are connected by adhesive. A reinforcing strip 7 is installed inside the slot 6, with the length of the reinforcing strip 7 in a 1:5 ratio to the length of the slot 6. The upper blade 1 and the lower blade 2 together constitute the racket's hitting body. To protect the internal structure and enhance the impact resistance of the edges, a full-circle rubber ring is provided at the edge where the upper blade 1 and the lower blade 2 meet. This rubber ring is typically made of elastic, aging-resistant rubber or silicone material, and is fixed to the edge of the racket body by covering or embedding, serving to seal, cushion, and prevent edge cracking or impact damage. Simultaneously, the main mating surfaces of the upper blade 1 and the lower blade 2 are connected by adhesive, i.e., bonded and fixed using a high-performance adhesive. This connection method ensures a uniform and firm surface contact between the two blades, effectively transferring hitting stress and maintaining a flat racket face. Repeated disassembly and reassembly of the sheath 3 can cause significant wear and stress to the slot 6, especially the initial section and stress-bearing area of the insert plate 32 where it is frequently inserted and removed. By controlling the length of the reinforcing strip 7 to 1 / 5 of the total length of the slot 6, precise localized reinforcement is achieved. It is positioned where enhanced wear resistance and deformation resistance are most needed, typically within approximately 1 / 5 of the front length of the slot 6. This effectively resists wear caused by repeated friction from the insert plate 32, preventing the slot 6 from deforming or cracking under stress, ensuring the long-term accuracy and stability of the sheath 3 installation. It also avoids unnecessary increases in material costs and handle weight associated with full-length reinforcement, achieving a balance between functionality and lightweight design.
[0033] The working principle is as follows: When using the racket, to quickly install the sleeve 3, simply insert the internal insert plate 32 into the slot 6 at the handle 5. The insert plate 32 will slide into the mating position via the guide groove 43 on the insert piece 41. At this time, the two V-shaped spring pieces 42 will exert a certain contraction force to control the insert piece 41 to insert into the slot 34 on the insert plate 32, achieving a fixed locking connection. Therefore, when using the racket, the sleeve 3 will be stable enough to form an integrated structure with the handle 5. During disassembly, the two insert pieces 41 need to be expanded to disengage from the slot 34. Because the insert plate 32 and the sleeve 3 are an integrated structure, contact with the limiting position of the insert plate 32 directly releases the limiting position of the sleeve 3. At this time, the user only needs to pull out the entire sleeve 3 to disassemble and replace it.
[0034] Furthermore, considering that users or athletes will inevitably sweat during prolonged training due to gripping the racket tightly, the more sweat accumulates, the worse the grip on the sleeve 3 will be, and it may even slip off the racket. Therefore, two sets of aerodynamic channels are designed. During the user's swing, the upper plate 1 and lower plate 2 act like a blade, and the airflow acts on the upper plate 1 and lower plate 2. At this time, the airflow passes through the two air inlets 44 and then into the air groove 53. The air groove 53 is a closed structure, so because the air groove... When vent 53 and air hole 33 are connected, the airflow will be discharged from the air hole 33 and then act on the user's palm, exiting through the fingers. When swinging the racket backward, the large angle 51 of the handle 5 will increase the wind-receiving area. The airflow will enter the air groove 52 from the large angle 51 and then exit from the other set of air holes 33 using the same principle, generating airflow that acts on the user's palm. This can greatly evaporate sweat and improve the user's grip.
[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
