[0002] Current bone conduction sound-generating lollipops generally employ a simple chip, speaker, and battery combination structure, without being specifically optimized for the characteristics of bone conduction transmission. In these products, the vibration component and the candy body are mostly in direct, rigid contact, resulting in significant energy loss during transmission. Furthermore, they cannot adapt to the vibration transmission requirements under different biting forces, leading to low sound efficiency; users need to bite down forcefully to hear the sound clearly. Simultaneously, the power supply system uses a fixed power output mode, failing to dynamically adjust power distribution based on the operating status of the vibration component, resulting in wasted battery energy and shortened product lifespan. In addition, the lack of coordinated coding logic between button controls and vibration sound generation leads to delays or false triggers in operation commands and sound responses, negatively impacting the user experience.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] Traditional technical solutions have the following problems: existing bone conduction sound-generating lollipops do not have an optimized vibration transmission structure, resulting in large vibration energy loss; fixed power supply distribution leads to energy waste; and the coordination between button control and sound response is poor.

[0018] Based on this, please refer to Figure 1-4This embodiment provides a lollipop based on bone conduction sound generation, including a lollipop body comprising a candy body and a stick body. The stick body houses a power supply unit, a customized multi-functional voice chip, a vibration component, and a button component. A vibration coupling optimization structure is provided between the candy body and the vibration component. The power supply unit is electrically connected to the customized multi-functional voice chip and the vibration component, forming a dynamic load distribution power supply system. The button component is electrically connected to the customized multi-functional voice chip and transmits commands through timing-coordinated coding control logic. The customized multi-functional voice chip is connected to the vibration component via signal lines. The vibration component receives the drive signal output by the customized multi-functional voice chip and generates vibration. The vibration is transmitted to the candy body through the vibration coupling optimization structure. The technical solution is described as follows: The lollipop body serves as the overall supporting foundation, with the candy body functioning as both an edible component and a vibration transmission carrier. After contacting the user's teeth, it can directly transmit vibration to the skull. The stick body adopts an internally hollow columnar structure, providing independent and non-interfering installation space for the power supply unit, customized multi-functional voice chip, vibration component, and button component, while ensuring the connection stability between the components. The power supply unit provides energy support for the entire system. Its output electrical energy is distributed to the vibration components as needed after being regulated by a customized multi-functional voice chip. This customized multi-functional voice chip is the core control module of the system. It not only receives operation signals transmitted from the button components but also decodes these signals and outputs matching drive signals to the vibration components based on the decoding results. Simultaneously, it sends load demand commands to the dynamic load distribution power supply system. The vibration coupling optimization structure is key to improving vibration transmission efficiency. Located between the vibration components and the candy body, it optimizes the transmission path of vibration energy, reducing losses to non-target carriers such as the rod during transmission and ensuring that the energy generated by the vibration components is transferred to the candy body to the maximum extent. The dynamic load distribution power supply system interacts with the customized multi-functional voice chip in real time, adjusting the power supply based on the vibration component's operating status as fed back by the chip, avoiding energy waste. The timing-coordinated coding control logic establishes a clear correspondence between button operations and device responses, ensuring that different operation commands can be accurately identified and executed. When the three work together, the user performs operations through the button component. The operation signal is converted into a specific electrical signal by the timing co-encoding control logic and transmitted to the customized multi-functional voice chip. After decoding, the chip sends a power adjustment command to the dynamic load distribution power supply system on the one hand, and outputs a drive signal to the vibration component on the other hand. The vibration generated by the vibration component is transmitted to the glycosome through the vibration coupling optimization structure, and is finally perceived by the user through the bone conduction path of teeth-skull-temporal bone.

[0019] The technical effects achieved by this solution include: improved vibration transmission efficiency, rational utilization of power supply energy, precise button control response, and stable bone conduction sound generation.

[0020] Traditional technical solutions have the following technical problems: existing vibration transmission structures lack adaptability design, vibration is easily affected by installation gaps, and transmission stability is poor.

[0021] Based on this, the vibration coupling optimization structure includes an elastic contact layer and a vibration transmission seat. The elastic contact layer is fixed to the end of the vibration component facing the candy, and the vibration transmission seat is sleeved on the outside of the vibration component and fixedly connected to the inner wall of the rod. The elastic contact layer is fitted and fixed to the bottom of the candy, and a preset gap is reserved between the inner wall of the vibration transmission seat and the outer wall of the vibration component. The technical solution of this scheme is described as follows: The elastic contact layer adopts a sheet-like structure, the size of which matches the vibration output end face of the vibration component. It is fixed to the end of the vibration component facing the candy by adhesive bonding, ensuring that the vibration generated by the vibration component can be completely transmitted to the elastic contact layer. The material of the elastic contact layer is selected to be both elastic and vibration-conducting, which can adapt to deformation under different biting forces of the user, always maintaining close contact with the bottom of the candy, and avoiding interruption or attenuation of vibration transmission due to changes in biting force. The vibration transmission seat is an annular sleeve structure, the inner diameter of which is slightly larger than the outer diameter of the vibration component. After being sleeved on the outside of the vibration component, it is fixed to the inner wall of the rod by a snap-fit ​​connection, realizing the radial positioning of the vibration component. The pre-set gap between the vibration transmission seat and the outer wall of the vibration component provides axial vibration space for the vibration component, preventing rigid collisions between the vibration component and the vibration transmission seat during vibration and reducing vibration energy loss. Simultaneously, the vibration transmission seat restricts the radial displacement of the vibration component, preventing changes in the vibration transmission path due to positional shifts during transportation or use. The elastic contact layer, in conjunction with the vibration transmission seat, forms a vibration transmission structure that allows for free axial vibration and stable radial positioning, ensuring both effective vibration energy transmission and improved vibration transmission stability.

[0022] The technical effects achieved by this solution include: enhanced vibration transmission stability, reduced interference from external factors on vibration transmission, and guaranteed consistency of bone conduction sound generation.

[0023] Traditional technical solutions have the following technical problems: existing power supply systems adopt a fixed output mode, which cannot adjust the power distribution according to the working status of components, resulting in low energy utilization.

[0024] Based on this, the dynamic load distribution power supply system includes a load detection unit and a distribution control unit. The load detection unit is electrically connected to the customized multi-functional voice chip and the vibration component, respectively. The distribution control unit is integrated inside the customized multi-functional voice chip. The load detection unit collects real-time load information from the customized multi-functional voice chip and the vibration component and transmits it to the distribution control unit. The distribution control unit adjusts the output power distribution ratio of the power supply unit according to the real-time load information. The technical solution is described as follows: The load detection unit consists of a current sensor and a voltage sensor. The current sensor is connected in series in the power supply circuit of the customized multi-functional voice chip and the vibration component to collect the operating current data in the circuit in real time. The voltage sensor is connected in parallel at the power supply terminals of the customized multi-functional voice chip and the vibration component to collect the operating voltage data at both ends in real time. The current and voltage data together constitute real-time load information, which is transmitted to the distribution control unit in real time through a signal transmission line. The distribution control unit is integrated inside the customized multi-functional voice chip, requiring no additional installation space. Its core function is to calculate the optimal power distribution ratio using a dynamic load distribution coefficient formula, which is: ; This formula, derived from the theory of dynamic load balancing and energy recovery technology, is used to quantify the power allocation coefficient of the power supply unit for different components. The power dynamic load distribution coefficient is dimensionless and directly determines the distribution ratio of power supply between the customized multi-functional voice chip and the vibration component. The load distribution coordination coefficient is dimensionless and reflects the degree of fit between power distribution and vibration coupling efficiency. It is determined through experimental calibration. Vibration coupling efficiency is the energy transfer efficiency of the vibration coupling optimized structure. It is dimensionless and its value is calculated by the vibration coupling efficiency formula. It reflects the impact of the working state of the vibration component on the power supply demand. The load switching duty cycle is dimensionless and refers to the proportion of time during which the power supply is switched per unit time. It is used to adapt to the dynamic changes in the operating state of components. The vibration energy recovery ratio is dimensionless and reflects the proportion of energy that is converted into electrical energy and recovered during the vibration process of the vibrating component. Energy recovery is achieved based on the principle of electromagnetic induction. This is a dimensionless ratio of standby power consumption. Dimensionless, it is obtained by comparing the actual standby power consumption with the baseline standby power consumption, reflecting the energy consumption characteristics of the customized multi-functional voice chip in its non-operating state. In the formula derivation, vibration coupling efficiency is considered first. The fundamental impact on power distribution, through Establish a positive correlation between the two; secondly, introduce the load switching duty cycle. Compared with vibration energy recovery ratio The product term reflects the regulatory effect of dynamic load changes and energy recovery on power distribution, through... This allows for dynamic adjustment of the basic allocation ratio; finally, subtract... This item compensates for the impact of the standby power consumption of the customized multi-functional voice chip on power allocation, ensuring that power allocation meets the working requirements of the vibration components without causing energy waste in standby mode. All parameters are dimensionless, ensuring that the formula has homogeneous dimensions, and the calculation results objectively reflect the optimal power allocation ratio. The allocation control unit calculates the power allocation ratio based on this formula. The value sends a power adjustment command to the power supply unit. When the vibration component is in a high-load sound-emitting state, As the value increases, the power supply unit increases its power output to the vibration component; when the customized multi-functional voice chip is in a low-load standby state, As the value decreases, the power supply unit reduces its overall output power and prioritizes ensuring the basic operating needs of the chip, thus achieving on-demand energy allocation.

[0025] The technical effects achieved by this solution include: improved power supply efficiency, extended battery life, and stable operation of all components.

[0026] Traditional technical solutions have the following technical problems: existing button controls lack clear coding rules, which can easily lead to false triggering or response delays, resulting in a poor user experience.

[0027] Based on this, the timing-coordinated coding control logic presets encoding rules corresponding to three operation commands. The first operation command is double-clicking the button component, corresponding to power-on and music playback encoding; the second operation command is single-clicking the button component, corresponding to music pause encoding; and the third operation command is long-pressing the button component, corresponding to power-off encoding. The button component collects the operation action and converts it into an electrical signal, which is transmitted to the customized multi-functional voice chip. The customized multi-functional voice chip encodes and recognizes the electrical signal and executes the corresponding control action. The technical solution of this scheme is described as follows: The timing-coordinated coding control logic is built into the control program of the customized multi-functional voice chip. It sets exclusive encoding sequences for the three button operations: double-click, single-click, and long-press. The encoding sequences are composed of combinations of high and low levels of different durations, and the three encoding sequences have significant differences in characteristics to avoid recognition confusion. The button component adopts a mechanical trigger structure and has an internal pressure sensor. When the user performs a button operation, the pressure sensor senses the pressure change and converts it into a corresponding electrical signal. The duration of the electrical signal and the number of pressure changes correspond one-to-one with the button operation type. To ensure the synergy between encoding recognition and vibration response, this logic quantifies the synergistic effect using a time-vibration synergistic encoding coefficient formula, which is as follows: ; This formula, derived from temporal coding theory and a physical response synergy model, is used to quantify the degree of synergy between key coding and vibration response. These are time-series-vibration co-coding coefficients, dimensionless. The closer the value is to 1, the better the synergy between encoding recognition and vibration response; The time-series coding cooperative gain is dimensionless and is used to adjust the sensitivity of the coding cooperative coefficients through experimental calibration. The power dynamic load allocation coefficient is dimensionless, representing the quantified value of power allocation in a dynamic load allocation power supply system, reflecting the supporting role of the power supply status in the coding response. The dimensionless width of the encoded pulse is obtained by the ratio of the actual encoded pulse width to the standard pulse width, reflecting the time characteristics of the encoded signal. This is a dimensionless timing coefficient for key presses, quantifying the timing characteristics of double-click, single-click, and long-press operations. Different operations correspond to fixed values. The value is used to distinguish the impact of operation type on collaboration; The dimensionless ratio of vibration response delay is obtained by comparing the actual vibration response delay with the reference delay, reflecting the response speed of the vibration component to the encoded command. In the formula derivation, the numerator part... The denominator comprehensively reflects the promoting effect of power supply status, coding characteristics, and operation type on coordination. This reflects the impact of vibration response delay and power distribution constraints on coordination; the ratio of the two is... Under the adjustment, the precise quantification of the timing-vibration coordination effect is achieved. All parameters are dimensionless, ensuring that the formula dimensions are homogeneous and the calculation results objectively reflect the coordination state. When the user performs a button operation, the button component converts the operation into an electrical signal and transmits it to a customized multi-functional voice chip. The chip first encodes and recognizes the electrical signal through timing-vibration coordination coding control logic to determine the operation command type, and simultaneously calculates the timing-vibration coordination coding coefficient. ,like If the value meets the preset threshold, the chip sends a power adjustment command to the dynamic load distribution power supply system and outputs a drive signal to the vibration component to ensure the coordination between code recognition and vibration response; if If the value does not meet the threshold, the chip re-identifies the encoded signal to avoid false triggering. The technical effects achieved by this solution include: accurate button operation recognition, timely response, reduced false triggering, and improved user operation convenience.

[0028] Traditional technical solutions have the following technical problems: the vibration coupling efficiency lacks quantitative calculation basis, making it impossible to accurately optimize structural parameters and affecting the vibration transmission effect.

[0029] Based on this, the vibration coupling efficiency of the vibration coupling optimization structure is calculated using the vibration coupling efficiency formula, which is: ; in The vibration mode coupling coefficient is... For the dimensionless ratio of meshing pressure, This is a dimensionless ratio of power supply capacity. The dimensionless ratio of the vibration frequencies of the vibrating components. This represents the damping coefficient of the elastic contact layer. The technical solution is described below: This formula is derived through a cross-disciplinary integration of mechanical vibration coupling theory and bone conduction acoustics principles. Its core purpose is to accurately quantify the energy utilization efficiency of the vibration coupling optimization structure during vibration transmission, providing a clear quantitative basis for structural parameter optimization. As a vibration mode coupling coefficient, it is dimensionless, and its value reflects the degree of fit between the vibration mode of the vibration component and the vibration receiving mode of the glycosome. The better the modal fit, the better the fit. The closer the value is to 1, the more accurate it is to determine the parameter. This parameter was calibrated through coupling experiments between vibrating components of different structural sizes and the glycosome. The dimensionless ratio of occlusal pressure is calculated by comparing the occlusal pressure exerted by the user's teeth on the sugar body during actual use with the preset benchmark occlusal pressure. The cubic relationship is used because occlusal pressure has a threshold effect on vibration transmission. When the actual occlusal pressure is lower than the benchmark pressure, the vibration transmission efficiency will drop sharply. The cubic form can amplify this threshold characteristic, making the formula more accurately reflect the influence of occlusal pressure. The dimensionless ratio of power supply is determined by the ratio of the actual power output from the power supply unit to the vibration component to the rated power of the vibration component. This parameter directly reflects the supporting effect of the power supply energy on the vibration intensity of the vibration component. The closer the actual power is to the rated power, the stronger the vibration intensity of the component. The closer the value is to 1, the more stable the vibration intensity of the vibration component and the higher the vibration transmission efficiency. The dimensionless ratio of the vibration frequency of the vibration component is the ratio of the actual operating vibration frequency of the vibration component to the resonant frequency of the bone conduction adapter. Bone conduction has the highest vibration reception efficiency within a specific frequency range. This parameter is used to ensure that the operating frequency of the vibration component is always within the bone conduction adapter range, thereby improving the effectiveness of vibration transmission. The damping coefficient of the elastic contact layer is dimensionless and used to quantify the energy loss of the elastic contact layer during vibration transmission. A smaller damping coefficient indicates less energy loss and higher vibration transmission efficiency. This parameter is directly related to the material hardness and thickness of the elastic contact layer. In the formula derivation, the core factors affecting vibration coupling efficiency are first analyzed, identifying the interlocking pressure, power supply, vibration frequency, and damping characteristics as key variables. Secondly, based on the mechanical vibration energy transmission formula, the variables are transformed into dimensionless ratios to avoid dimensional coupling conflicts. Then, through the numerator... This comprehensively reflects the promoting effect of meshing pressure, power supply, and vibration frequency on coupling efficiency. (The denominator is missing from the original text.) This demonstrates the suppressive effect of damping coefficient and frequency characteristics on coupling efficiency; finally, the vibration mode coupling coefficient is introduced. The overall ratio is corrected to ensure that the formula calculation results accurately reflect the actual vibration coupling efficiency. All parameters are dimensionless, strictly adhering to the principle of dimensional homogeneity; the dimensions on both sides of the equation are completely identical, the dimensions of the addition and subtraction terms are the same, and the combination of dimensions of the multiplication and division terms conforms to the laws of physics. Using this formula, the calculated... By adjusting parameters such as the material damping coefficient of the elastic contact layer and the vibration frequency of the vibration component, the vibration coupling efficiency can be precisely optimized.

[0030] The technical effects achieved by this solution include: the vibration coupling efficiency can be accurately quantified, providing data support for structural parameter optimization and improving the controllability of vibration transmission.

[0031] Traditional technical solutions have the following technical problems: they lack status indication functions, and users cannot intuitively understand the working status of the equipment.

[0032] Based on this, an indicator light is also provided inside the device. The indicator light is electrically connected to the power supply unit and the customized multi-functional voice chip, respectively. The customized multi-functional voice chip outputs a drive signal to the indicator light, and the indicator light indicates its status according to the drive signal. The technical solution is described as follows: The indicator light adopts a surface-mount structure and is installed on the device near the button assembly for easy observation by the user. Its operating voltage is compatible with the output voltage of the power supply unit, eliminating the need for an additional voltage conversion module. The two pins of the indicator light are connected to the positive terminal of the power supply unit and the indicator light drive pin of the customized multi-functional voice chip via wires, forming a complete power supply circuit. The customized multi-functional voice chip generates different drive signals according to the device's operating status. When the device is in the power-on playback state, the chip outputs a continuous high-level drive signal, providing stable power to the indicator light, which remains constantly lit. When the device is in the paused state, the chip outputs an intermittent high-level drive signal, and the indicator light flashes at a fixed frequency. When the device is in the power-off state, the chip outputs a low-level drive signal, and the indicator light turns off. The generation of drive signals and the chip's encoding and recognition of button operations are carried out synchronously, ensuring that the indicator light status matches the device's working status in real time. This allows users to intuitively determine whether the device is currently in working status and the type of working status by observing the on / off state of the indicator lights.

[0033] The technical effects achieved by this solution include: visualizing equipment status, allowing users to monitor equipment operation in real time and improving the user experience.

[0034] Traditional technical solutions have the following technical problems: insufficient stability of the power supply unit, which is prone to voltage fluctuations or damage to components due to reverse connection.

[0035] Based on this, the power supply unit includes two LR44 button batteries connected in series and two capacitors connected in series. The two LR44 button batteries provide the power supply voltage, and the two capacitors are connected in parallel with the two LR44 button batteries. The power supply unit is connected to the power pin of the customized multi-functional voice chip through a power management line, and a reverse connection protection element is provided on the power management line. The technical solution is described as follows: The two LR44 button batteries are connected in series and fixed inside the rod body by a battery holder. The output voltage after series connection can meet the working voltage requirements of the customized multi-functional voice chip and vibration components, ensuring that each component receives a stable basic power supply. The two capacitors are connected in series, and the total capacitance of the capacitors after series connection matches the output characteristics of the power supply unit. Their two ends are connected in parallel with the positive and negative terminals of the two series button batteries, respectively, forming a filter circuit. Capacitors have charging and discharging characteristics. When the battery output voltage fluctuates, the capacitor can store electrical energy by charging or release electrical energy by discharging, quickly compensating for voltage fluctuations and keeping the output voltage of the power supply unit stable. This reduces the impact of voltage fluctuations on the operational stability of the customized multi-functional voice chip and vibration components. The power management circuit uses copper wires, with one end connected to the output terminal of the battery holder and the other end connected to the power pin of the customized multi-functional voice chip. A reverse connection protection element is connected in series on the circuit. This element is a unidirectional conductive device, allowing current to flow only from the positive terminal of the battery to the power pin of the chip. When the battery is installed in reverse, the reverse connection protection element is cut off, and the current cannot form a loop, thus preventing reverse current from flowing into the chip and vibration components and causing damage to the components. This ensures the safe and stable operation of the power supply system and the entire device.

[0036] The technical benefits achieved by this solution include: stable power supply voltage, improved component safety, and extended equipment lifespan.

[0037] Traditional technical solutions have the following technical problems: unreasonable chip packaging and pin configuration, which affect installation compatibility and signal transmission stability.

[0038] Based on this, the customized multi-functional voice chip adopts an SOP8 package. The pins of the customized multi-functional voice chip include power pins, ground pins, key input pins, and vibration component drive pins. The power pin is electrically connected to the power supply unit, the ground pin is connected to the grounding line inside the device, the key input pin is electrically connected to the key assembly, and the vibration component drive pin is connected to the vibration component through the signal line. The technical solution is described as follows: The SOP8 package is a small-size surface-mount package. Its compact size, neat pin arrangement, and standard spacing allow it to fit within the limited installation space inside the device. It also facilitates surface-mount mounting on the PCB, improving the chip's mounting stability. Of the eight pins of the customized multi-functional voice chip, the power pin is specifically used to receive power from the power supply unit, providing operating power to the chip's internal circuitry. Its current carrying capacity matches the output current of the power supply unit, ensuring stable power input. The grounding pin is connected to the grounding line inside the rod body. The grounding line uses copper foil laid on the PCB board and connected to the outer shell of the rod body. This allows static electricity and noise signals generated during chip operation to be conducted to the ground, preventing noise signals from interfering with the normal operation of the chip and ensuring signal processing accuracy. The button input pin is specifically used to receive electrical signals transmitted by the button assembly. Its input impedance matches the output impedance of the button assembly, reducing attenuation and distortion during signal transmission and ensuring that the chip can accurately receive button operation signals. The vibration component drive pin is used to output drive signals to the vibration component. Its output power is adapted to the driving requirements of the vibration component, providing sufficient driving energy. At the same time, the frequency and waveform of the output signal can be dynamically adjusted according to the chip's control commands to achieve different vibration effects. Each pin has a clear and independent function, avoiding signal interference caused by functional overlap. The connection between the pins and external components is achieved through dedicated wires or PCB lines, with short and fixed connection paths, further improving the stability and reliability of signal transmission.

[0039] The technical benefits achieved by this solution include: strong chip installation compatibility, stable signal transmission, and ensuring the overall reliability of the equipment.

[0040] Traditional technical solutions have the following technical problems: improper selection of vibration components and contact layer materials, which affect the vibration transmission effect and safety of use.

[0041] Based on this, the vibration component is a miniature bone conduction speaker. The vibration output end of the miniature bone conduction speaker is fixedly connected to the elastic contact layer of the vibration coupling optimization structure. The elastic contact layer is made of food-grade silicone material, and the vibration conduction base is made of rigid plastic material. The technical solution is described as follows: The miniature bone conduction speaker is a vibration-generating element specifically designed for small portable devices. It is compact, lightweight, and can fit within the internal installation space of the speaker. It also features high vibration intensity and low energy loss. Its working principle is to drive a diaphragm to generate mechanical vibration through an internal electromagnetic coil. The vibration frequency of the diaphragm is synchronized with the audio signal frequency, enabling accurate reproduction of music and other audio content. The vibration output end of the miniature bone conduction speaker has a planar structure and is fixedly connected to one side of the elastic contact layer by adhesive bonding. The connection surfaces are completely fitted, ensuring that the vibration generated by the speaker can be completely transmitted to the elastic contact layer, avoiding vibration loss due to connection gaps. The elastic contact layer is made of food-grade silicone, which meets food contact safety standards, is non-toxic and odorless, and will not affect the user's health. It also possesses excellent elasticity and vibration transmission properties. Its elasticity allows it to adapt to deformation when the user bites, maintaining close contact with the candy, while its vibration transmission properties ensure efficient transfer of vibration energy. The vibration transmission base is made of rigid plastic, which has sufficient structural strength to withstand the vibration impact of the vibration assembly and the fixing stress during installation, preventing displacement of the vibration assembly due to structural deformation. Simultaneously, the low damping coefficient of rigid plastic minimizes vibration energy absorption and loss, ensuring normal vibration of the assembly. These three components work together to form a vibration transmission system of "vibration generation - efficient transmission - stable support," guaranteeing both effective vibration transmission and meeting food safety requirements.

[0042] The technical benefits achieved by this solution include: good vibration transmission, safe and reliable use, and compliance with the requirements for food contact materials.

The rod body is made of insulating material, and the surface of the rod body is textured. The technical solution of this method is described as follows: The tactile button features low operating force, sensitive response, and long service life. It has a metal spring inside. When the user presses the button, the metal spring deforms and conducts the circuit, generating an electrical signal. After releasing the button, the metal spring resets, and the circuit is broken, which can accurately capture the user's pressing operation. The pins of the tactile button are made of metal and are connected to the button input pins of the customized multi-functional voice chip via soldering. The solder joint is strong and stable with low resistance, which can reduce poor contact and signal attenuation during signal transmission, ensuring that the button operation signal can be transmitted to the chip quickly and accurately. The rod body is made of insulating material. This material is non-conductive, which can isolate the internal power supply unit, customized multi-functional voice chip, and other charged components from the outside, avoiding the risk of electric shock to the user during use. At the same time, this material has a certain mechanical strength, which can protect the internal components from external impacts. The surface of the stick has evenly distributed textures with alternating concave and convex structures, which increases the friction between the user's fingers and the stick's surface. Even when hands are sweaty or there is sugar residue, it can effectively prevent the stick from slipping out of the hand. At the same time, the texture structure is ergonomically designed, which can distribute finger pressure when holding the stick, improve grip comfort, and reduce fatigue caused by prolonged holding.

[0045] The technical benefits achieved by this solution include: stable button connection, comfortable and safe grip, and improved overall user experience.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
