Bone conduction-based sound-generating lollipops, processing methods, and systems

Abstract

This invention provides a bone conduction-based sound-generating lollipop, a processing method, and a system. The bone conduction-based sound-generating lollipop includes a shell, a trigger, a controller, and a sound-generating component. The sound-generating component, controller, and trigger are integrated into an encapsulated cavity formed by the shell, eliminating the need for separate encapsulation of the sound-generating component. When the support portion of the shell enters the human mouth, the trigger sends an activation command to the controller, which drives the sound-generating component to vibrate. The vibration signal is transmitted to the human auditory system via bone conduction through the support portion of the shell and the edible material attached to the support portion, through the oral tissue or teeth. Compared to existing bone conduction-based sound-generating lollipops, the elimination or reduction of the encapsulated shell of the traditional sound-generating structure simplifies the structure of the bone conduction sound-generating component, increases its integration, achieves miniaturization of the bone conduction-based sound-generating lollipop, and reduces sound quality loss, thereby improving sound quality.

Description

Technical Field

[0001] This application relates to the field of bone conduction technology, and more particularly to a lollipop based on bone conduction sound generation, a processing method, and a system. Background Technology

[0002] As people's living standards improve, a new type of candy, different from traditional candy, has gradually emerged—the talking lollipop. Talking lollipops typically use a stick-shaped handle that makes a sound instead of the original lollipop stem. The candy is directly attached to one end of the handle, while the sound-producing part is located at the other end.

[0003] Traditional talking lollipops use ordinary loudspeakers, and the sound they play can be heard by the user and everyone around them, which can easily disturb those around them and is not conducive to protecting the user's privacy. As a result, the corresponding products are of low quality and have a poor user experience.

[0004] Applying existing bone conduction sound technology directly to sound-generating lollipops presents significant drawbacks. Existing bone conduction vibration components suffer from narrow frequency ranges, high distortion, significant low- and high-frequency attenuation, and high power consumption. Traditional air-transmitting loudspeakers address these issues by adding multiple loudspeakers with different frequency characteristics to create a spatial surround sound network, improving sound quality through multiple loudspeakers providing stereo surround sound. However, applying the same method to bone conduction lollipops is severely constrained by the size of the lollipop and the limited installation space. Increasing the number of bone conduction components significantly increases the size and weight of the lollipop, potentially making it inedible. This inability to ingest sound leads to severe sound leakage from the bone conduction device, negating the purpose of using bone conduction for sound generation and ultimately resulting in poor sound quality in bone conduction sound-generating lollipops.

[0059] The controller receives an activation command via the trigger, or determines whether the lollipop has entered the mouth of the object to be transmitted sound or has come into contact with the teeth via the trigger.

[0060] When the controller determines that it has received the activation command, or when the trigger determines that the lollipop has entered the mouth or teeth of the object to be transmitted sound, it drives the sound-generating component to generate a vibration signal, so as to transmit the vibration signal to the auditory system of the object to be transmitted sound through the at least one support and the lollipop.

[0065] Optionally, when the controller detects, based on the pressure sensor, that the number of times the teeth in the human oral cavity touch the lollipop within a preset interval range has reached a preset number, it adopts an operation mode corresponding to the preset number of times to operate the sound source.

[0066] Optionally, the operating mode includes one or more of the following:

[0067] Fast forward, rewind, skip to the next audio program, skip to the previous audio program, lower preset volume, and raise preset volume.

[0068] In one possible design, the controller reduces the volume of the sound source when the pressure sensor detects that the pressure change range of touching the lollipop exceeds a preset threshold range.

[0069] In one possible design, any of the above-described bone conduction-based lollipop processing methods:

[0070] When the controller determines that the lollipop has entered the human mouth, it uses a timer to record the time the lollipop has been in the mouth.

[0071] The controller determines the degree of melting of the lollipop based on the time recorded by the timer in the mouth, and adjusts the volume of the sound source accordingly based on the degree of melting.

[0072] The present invention provides a bone conduction-based sound-generating lollipop, processing method, and system. The bone conduction-based sound-generating lollipop includes a shell, a trigger, a controller, and a sound-generating component. The sound-generating component, controller, and trigger are integrated into an encapsulated cavity formed by the shell, eliminating the need for separate encapsulation of the sound-generating component.

The vibration signal is transmitted to the human auditory system via bone conduction through the support portion of the shell and the edible material attached to the support portion, through the oral tissue or teeth. Compared with existing bone conduction sound-generating lollipops, the elimination or reduction of the encapsulated shell of the traditional sound-generating structure makes the structure of the bone conduction sound-generating component simple and highly integrated, achieving miniaturization of the bone conduction-based sound-generating lollipop and reducing sound quality loss, thereby improving sound quality.

These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0083] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0084] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0085] The technical solutions of the present invention and how they solve the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0086] Existing bone conduction-based lollipops suffer from limitations due to the narrow frequency range, high distortion, significant attenuation at low and high frequencies, and high power consumption of existing bone conduction vibration-generating components. Furthermore, the existing components are individually packaged with an encapsulation shell, and the lollipop itself also has an outer shell. This increases the vibration transmission path, causing some frequencies to be lost due to the encapsulation shell, resulting in a decrease in sound quality. While existing bone conduction-based lollipops can improve sound quality by using multiple bone conduction devices, this significantly increases the number, size, and weight of the equipment. The increased size makes it difficult for users to put the lollipop in their mouths, leading to severe sound leakage, which not only affects sound quality but also compromises user privacy.

[0087] Based on the above-mentioned technical problems, this embodiment provides an integrated bone conduction sound-generating lollipop. By utilizing an integrated bone conduction sound-generating device, not only can the original volume of the lollipop be maintained to a certain extent, but the sound quality can also be effectively improved. That is, it is convenient for users to put on the lollipop while also effectively improving the sound quality.

[0088] Figure 1 This is a schematic diagram of a lollipop based on bone conduction sound generation, provided as an embodiment of the present invention. Figure 1As shown, the bone conduction-based sound-generating lollipop of this embodiment includes a shell 1 and a sound-generating component 5, a controller 2, and a trigger 21 disposed within the shell 1. The shell 1 includes at least one support portion 11 adapted to be placed into the mouth, and the support portion 11 is used to support the edible substance 7.

[0089] Optionally, the sound-generating component 5 includes at least one power receiving element 3 and at least one vibration element 4. The controller 2 is electrically connected to the power receiving element 3 via a wire. When the user issues an activation command through the trigger 21;

[0090] Alternatively, when trigger 21 detects that the lollipop has entered the user's mouth, controller 2 receives the activation command from trigger 21 and transmits an electrical signal containing sound information to at least one powered element 3. The powered element 3, excited by the electrical signal, generates a changing magnetic field, causing vibrating element 4 to produce a vibration signal. This vibration signal is transmitted through the outer shell 1 to the edible object 7, and is suitable for transmission to the auditory system via bone conduction. When the edible object 7 or support 11 comes into contact with the human mouth or teeth, the vibration signal is transmitted through the outer shell 1 and the edible object 7 to the muscle tissue or teeth and bones of the human mouth, and then to the human auditory system. That is, the vibration signal is transmitted to the auditory system via bone conduction. The vibration signal can also be directly transmitted to the auditory system through the outer shell 1 via bone conduction.

[0091] It should be noted that the user mentioned in this embodiment can be a human or other animals with a mouth, such as a dog or a cat. This embodiment does not limit the user. In this embodiment and subsequent examples, the application of the bone conduction sound lollipop to a human is mainly used as an example for detailed explanation.

[0092] Figure 2 A schematic diagram of a lollipop based on bone conduction sound generation, provided for another embodiment of the present invention. (See diagram below.) Figure 2 As shown, in this embodiment, the outer casing 1 further includes a handle-shaped portion 12, and the support portion 11 is connected to the handle-shaped portion 12. Optionally, the handle-shaped portion includes a connecting section 121, a system section 122, and a sound-leakage prevention structure or material 121a attached to the inner wall of the connecting section 121. One end of the connecting section 121 is connected to the support portion 11, and the other end is connected to the system section 122. The controller 2 is placed within the system section. The controller 2 is connected to the power receiving element 3 in the sound-generating component 5 within the support portion 11 via a wire passing through the connecting section 121, thereby enabling the controller 2 to transmit electrical signals to the power receiving element 3.

[0093] This distributed layout can further reduce the volume of the support part 11, or allow more space in the support part 11 to increase the number of power receiving elements and vibrating elements, thereby increasing the frequency range of the vibration frequency characteristics and improving sound quality. The anti-leakage structure or anti-leakage material 121a can prevent vibration from being transmitted to the handle-shaped part when the support part vibrates, thus preventing sound leakage and improving the sound quality of the bone conduction lollipop. This also protects the user's privacy and avoids interference with the surrounding environment.

[0094] It should be noted that the difference between the sound-generating component 5 in this embodiment and the sound-generating structure in a traditional bone conduction sound-generating device is that the traditional sound-generating structure has an independent outer shell that encapsulates the sound-generating structure. Existing technologies for improving the sound quality of bone conduction sound-generating devices involve increasing the number of sound-generating structures in different frequency domains. However, traditional sound-generating structures are all individually encapsulated, which geometrically increases the volume and weight occupied by the outer shell, and the production cost also increases accordingly. Furthermore, the encapsulated outer shell increases the transmission distance of vibration, causing the vibration signal to attenuate, resulting in sound quality loss.

[0095] Optionally, the sound-generating component 5 described in the above embodiments includes related actuators capable of generating vibrations. Through creative exploration in practice, the inventors of this application have discovered that the sound-generating structure 5 can be packaged by integrating multiple vibration actuators together, or by relying on the outer shell 1 of a lollipop based on bone conduction sound generation. That is, the sound-generating component 5 is embedded in the cavity 13 formed by the outer shell 1, or the outer shell 1 encloses the sound-generating component 5. The packaging of the sound-generating component 5 can also be shared with the controller 2, i.e., the sound-generating component 5 is integrated with the controller 2. Alternatively, the packaging of the sound-generating component 5 can be integrated with the controller 2 and the outer shell 1 into a single package, such as... Figure 1 As shown, the three components are integrated into the cavity 13 formed by the outer shell.

[0096] The bone conduction-based sound-generating lollipop provided in this embodiment includes a shell, a trigger, a controller, and a sound-generating component. The sound-generating component, controller, and trigger are integrated into the encapsulated cavity formed by the shell, eliminating the need for separate encapsulation of the sound-generating component. When the support portion of the shell enters the human mouth, the trigger sends an activation command to the controller, which drives the sound-generating component to vibrate. The vibration signal is transmitted to the human auditory system via bone conduction through the support portion of the shell and the edible material attached to the support portion, through the oral tissue or teeth. Compared to existing bone conduction sound-generating lollipops, the elimination or reduction of the encapsulated shell of the traditional sound-generating structure makes the structure of the bone conduction sound-generating component simple and highly integrated, achieving miniaturization of the bone conduction-based sound-generating lollipop and reducing sound quality loss, thereby improving sound quality.

[0097] Figure 3 This is a schematic diagram of a lollipop based on bone conduction sound generation, provided as another embodiment of the present invention. Figure 3 As shown, in this embodiment, the edible substance 7 includes foods such as candy, chocolate, teething sticks, and dried meat, or it can be medicine. Furthermore, the edible substance 7 can be composed of two or more different edible substances.

[0098] Optionally, the edible material 7 can be a rigid material or a gelatinous material with high hardness, suitable for transmitting vibration signals. A gelatinous material refers to a semi-solid gel material that can maintain a certain shape, such as agar.

[0099] In one possible implementation, the edible ingredient 7 may have a liquid filling, specifically, such as Figure 3 As shown, the edible material 7 includes an outer layer 71 and an inner layer 72, with the outer layer 71 covering the outer side of the inner layer 72. The inner layer 72 can be a liquid material, such as liquid syrup or other liquid edible materials, while the outer layer 71 can be a rigid material or a hard gel material, suitable for contacting teeth to transmit vibration signals and preventing the liquid inner layer 72 from flowing out. The liquid material of the inner layer 72 includes solutions, suspensions, and emulsions.

[0100] Optionally, the bone conduction-based sound-emitting lollipop can have a predetermined sound-emitting time, such as 10 minutes. The amount of edible substance 7 is sufficient to maintain the predetermined sound-emitting time, so that the edible substance 7 is not completely consumed when the sound information is played. This allows users to enjoy the deliciousness of the food and experience the beauty of the music while using the bone conduction-based sound-emitting lollipop, enhancing the user's pleasure and user experience.

[0101] In addition, in this embodiment, the trigger 21 (not shown in the figure) may also include a sensor. The sensor can generate a corresponding trigger signal, i.e., an activation command, by detecting the usage environment of the lollipop based on bone conduction sound generation. The controller 2 can then drive the sound-generating component to vibrate according to the activation command.

[0102] Optionally, the sensor may include one or more of the following: pressure sensor, light sensor, temperature sensor, humidity sensor, and capacitive sensor.

[0103] In one possible design, when the sensor is a pressure sensor, when the user puts the lollipop in their mouth and bites it with their teeth, the edible object 7 will transmit pressure to the outer shell 1, thereby causing the pressure sensor attached to the outer shell 1 to detect the stress change and generate an electrical signal, which is the start command.

[0104] Optionally, the user can tap the lollipop shell 1 or the edible part 7 a preset number of times within a preset time interval using their teeth. At this time, the pressure sensor detects the user's actions and converts the touches into electrical signals, which are then transmitted to the controller 2. The controller 2, based on preset mode determination conditions, enters the corresponding operating mode to operate the sound source. For example, if the user continuously bites and taps the edible part 7 with their teeth within 2 seconds, and the pressure sensor detects two pressure changes, the controller 2 will automatically play the next song.

[0105] It is understood that the above-mentioned operation modes include: fast forward, rewind, skip to the next audio program, skip to the previous audio program, decrease preset volume, and increase preset volume. Those skilled in the art can set the operation modes and their corresponding triggering conditions according to specific circumstances. For similar operations, this invention will not elaborate further; that is, this invention does not specifically limit the scope of the operation modes.

[0106] Optionally, users can also change the corresponding operation mode by varying the pressure applied when touching the lollipop. When the pressure change detected by the pressure sensor is greater than or less than a preset threshold range, the controller 2 adopts the corresponding operation mode to operate the sound source according to the preset pressure threshold. For example, when the user is almost finished eating the edible item 7, the bone conduction vibration will transmit more vibration energy due to the reduced conduction distance, causing the user to perceive a louder volume. At this time, the user can bite down hard on the support part 11 of the bone conduction lollipop. The pressure sensor detects that the pressure value is greater than the preset pressure threshold and transmits this signal to the controller 2. The controller recognizes the user's preset intention and reduces the volume of the sound source, that is, it controls the vibration intensity of the generating component 5 to reduce the volume.

[0107] In another possible design, when the sensor is a light sensor, the user puts the lollipop in their mouth, the light sensor detects a change in the surrounding brightness, generates an electrical signal, i.e., an activation command, and the controller 2 takes corresponding actions on the sound source according to the activation command.

[0108] In another possible design, the sensor includes one or more of the following combinations: temperature sensor, humidity sensor, and capacitance sensor. Because the temperature of the oral cavity is higher than that of the external environment, and the humidity of the oral cavity is also different from that of the outside world, and the bodily fluids in the skin of the oral cavity will also cause changes in capacitance, these characteristics of the oral cavity can be used to detect whether the bone conduction lollipop is being used by the user, thereby realizing the function of automatic opening and improving the user experience.

[0109] It is understandable that those skilled in the art can also combine the above sensors to increase the complexity of the judgment, thereby improving the accuracy of judging the user's intention when using a lollipop based on bone conduction sound.

[0110] Furthermore, based on the above embodiments, in another embodiment of the present invention, the lollipop based on bone conduction sound generation may also include a timer. When a user places the lollipop in their mouth or bites it, the sensor detects the user's action. The controller 2, recognizing the user's use of the lollipop through the sensor, instructs the timer to start timing. Since the edible substance 7 melts continuously over time in the mouth, the controller 2 can predict the degree of melting of the lollipop based on the time recorded by the timer, thereby adjusting the volume of the sound source accordingly. This enables the lollipop to automatically adjust its volume, improving the user experience and enhancing the product's perceived quality.

[0111] In another embodiment of the present invention, the controller 2 may further include a memory, in which sound information can be pre-stored. The controller 2 converts the pre-stored sound information into corresponding electrical signals and transmits them to the corresponding sound-generating component 5. The memory can be any device suitable for storing information and facilitating the control system to obtain information, including semiconductor memory, magnetic surface memory, etc.

[0112] Optionally, the controller 2 may also include an identification chip for establishing a communication connection with an external device and performing verification interaction processing with the external device.

[0113] In this example, when a user enters a place with a purchased lollipop, a communication connection can be established between the identification chip embedded in the lollipop and an external device, namely the entry verification device. Then, the electronic ticket in the identification chip is verified using Radio Frequency Identification (RFID) technology or other methods, so that the user no longer needs to carry a separate ticket, thereby effectively increasing the utilization rate of the lollipop. It can not only be used to enjoy the lollipop while listening to the sound data they need, but also as an entry and exit credential.

[0114] Optionally, the controller 2 may also include a data input interface for receiving sound information sent by external devices in a wired and / or wireless manner. The control system can convert the sound information sent by the external devices into corresponding electrical signals and transmit them to the corresponding sound-generating component 5 to drive the sound-generating component 5 to vibrate.

[0115] The data input interface includes interfaces such as USB interface, eSATA interface, SD card interface, Micro SD card interface, audio input interface, video input interface, Wi-Fi interface, Bluetooth interface, metal electrodes, and microphone, which are suitable for receiving electrical signals, radio waves, magnetic signals, optical signals, etc. containing sound information; the data input interface may include one of the above interfaces or a combination of multiple interfaces.

[0116] That is, the controller 2 can convert the sound information stored in the memory or the sound information obtained from the data input interface into corresponding electrical signals to drive the sound-generating component 5.

[0117] It should be noted that the receiving element 3 can drive the vibrating element 4 to vibrate in various ways. During the process of converting the electrical signal sent by the controller 2 into a vibration signal, the energy between the receiving element 3 and the vibrating element 4 can be of various forms, including magnetic field energy, thermal energy, mechanical energy, etc. The receiving element 3 and the vibrating element 4 can be various components that can work together to convert electrical signals containing sound information into corresponding vibration signals.

[0118] Furthermore, the sound-generating component 5 in the above embodiments of the present invention can be implemented in various ways. The structure of the sound-generating component 5 will be described in detail below.

[0119] Figures 4a-4e These are schematic diagrams illustrating various implementations of the transducer unit in the sound-generating component according to different embodiments of the present invention. For example... Figure 4a As shown, in one optional embodiment, the sound-generating component 5 includes at least one power receiving element and at least one vibrating element. Figure 4a The receiving element is the first coil 31, and the vibrating element is the magnet 41, but the specific forms of the receiving element and the vibrating element are not limited to these.

[0120] It should be noted that the magnet 41 in this embodiment can also be a magnet composed of a coil, or a magnet composed of both a coil and a magnet. Similarly, the first coil 31 can also be a magnet composed of a coil and / or a magnet. In this application, a magnet refers to a component or structural module capable of generating a magnetic field. The magnets and coils mentioned in the following embodiments can have similar implementations, which will not be repeated here. This invention does not limit the specific form of the magnet; any component capable of generating a magnetic field falls within the scope of the magnets described in this invention.

[0121] The first coil 31 and the magnet 41 form a transducer unit 51. The transducer unit 51 generates a vibration signal according to the electrical signal sent by the controller 2 (not shown in the figure). When both the energized element and the vibrating element are defined, the frequency response characteristics of the transducer unit 51 are determined, and the sound-generating component has a fixed frequency response curve. In this embodiment, the function of the transducer unit 51 is to convert electrical energy into a magnetic field through the first coil 31. The energized first coil 31 generates a magnetic field, which interacts with the magnet 41, causing the magnet 41 to apply pressure to the support 11 through a mechanical connection, causing the support 11 to deform. The strength of the magnetic field is adjusted by an electrical signal, which changes the deformation accordingly, causing the support 11 and the magnet 41 to vibrate together. This realizes the conversion of the electrical signal sent by the controller 2 into a vibration signal carrying sound information, thus achieving vibration and sound generation.

[0122] Optionally, the transducer unit 51 may also include at least one elastic structure or elastic element 6 connected to the support part 11 to transmit the vibration signal generated by the vibration element to the support part 11. The elastic element or elastic structure 6 includes springs, rubber blocks, etc. The frequency response characteristics of the corresponding transducer unit 51 can be adjusted by adjusting the specific form, structure, material and other parameters of the elastic element or elastic structure 6.

[0123] Figures 4b to 4e These are schematic diagrams of the second to fifth types of transducer units in this embodiment. Figures 4b to 4e As shown, in another optional embodiment, the sound-generating component 5 includes at least two powered elements and / or at least two vibrating elements, thereby forming at least two sets of transducer units. Each transducer unit generates a corresponding vibration signal in response to an electrical signal sent by the controller 2 (not shown). When the transducer unit includes at least two powered elements and the powered elements are first coils, multiple first coils can be arranged coaxially, side-by-side, or in other ways. In each transducer unit, if there are multiple sets of vibrating groups formed by magnets and coils, each vibrating group can have different frequency response characteristics. Further optionally, each set of transducer units can have the same frequency response characteristics or different frequency response characteristics. When multiple transducer units have two or more frequency response characteristics, the control system can drive different transducer units to work with different frequency response curves. Therefore, one or more sets of transducer units with specific frequency response characteristics can be selected to vibrate according to specific circumstances, which can significantly improve sound quality.

[0124] like Figure 4b As shown, in one optional embodiment, the number of power receiving elements and vibration elements are the same, and the power receiving elements and vibration elements correspond one-to-one. Each power receiving element is electrically connected to the control system 2 and drives a corresponding vibration element to vibrate, thereby forming multiple sets of transducer units. Figure 4bThe bone conduction-based sound-generating lollipop shown includes two receiving elements and two vibrating elements, forming two sets of transducer units, namely transducer unit 521 and transducer unit 522. The frequency response characteristics of these multiple sets of transducer units can differ. The controller 2 can drive one or more sets of transducer units with corresponding frequency response characteristics to vibrate according to the frequency band characteristics of the sound information. Specifically, the controller 2 sends corresponding electrical signals to the set of transducer units whose resonant peak frequency matches the frequency band characteristics of the sound information most closely. Figure 4b In this device, the receiving elements are the first coil 321 and the first coil 322, and the vibrating elements are the magnet 421 and the magnet 422, but the specific forms of the receiving elements and the vibrating elements are not limited to these.

[0125] In another alternative implementation, such as Figure 4c As shown, the sound-generating component includes at least two vibrating elements and forms at least two sets of transducer units, and the at least two sets of transducer units share a common power receiving element, that is, at least one power receiving element is capable of driving two or more different vibrating elements. Figure 4c In this design, the receiving element is the first coil, and the vibrating element is a magnet. Of course, the receiving element and the vibrating element can also be other components. For example... Figure 4c As shown, the sound-generating component includes a first coil 331 and two magnets 431 and 432. The two magnets 431 and 432 are respectively positioned on both sides of the first coil 331, and both magnets 431 and 432 are within the effective range of the magnetic field generated by the first coil 331. That is, the first coil 331 can drive both magnets 431 and 432, thus forming two sets of transducer units, namely transducer unit 531 and transducer unit 532. Of course, the two magnets 431 and 432 can also be positioned on the same side of the first coil 331. The weight, size, material, and magnetic gap between the two magnets 431 and 432 and the first coil 331 can be different, thus giving the two sets of transducer units 531 and 532 different frequency response characteristics. When the controller 2 sends an electrical signal to the first coil 331, the two magnets 431 and 432 are driven to vibrate. Thus, the vibration signal output by the bone conduction-based sound-generating lollipop is the superposition of the two sets of transducer units 531 and 532. This can improve the sound quality of the bone conduction-based sound-generating lollipop and reduce the overall size of the sound-generating component. Figure 4c The two sets of transducer units 531 and 532 can form a transducer unit pair. Those skilled in the art can set one or more such transducer units in the sound-generating component according to actual needs. Figure 4c The transducer pair shown.

[0126] In another alternative implementation, such as Figure 4d and Figure 4eAs shown, the sound-generating component includes at least two powered elements forming at least two sets of transducer units, and the at least two sets of transducer units share a common vibrating element, that is, at least one vibrating element can be driven to vibrate by at least two powered elements respectively, thereby reducing the overall volume of the sound-generating component. Figure 4d In this configuration, the receiving element is the first coil, and the vibrating element is a magnet. Figure 4e In this design, the receiving element is a piezoelectric element, and the vibrating element is a diaphragm. Understandably, the receiving element and the vibrating element can also be other types of components.

[0127] Further optional, such as Figure 4d As shown, the sound-generating component includes two first coils 341 and 342 and a magnet 44. The magnet 44 is within the effective range of the magnetic fields generated by the two first coils 341 and 342, meaning that the magnet 44 can be driven by both the first coils 341 and 342, thus forming two sets of transducer units, namely transducer unit 541 and transducer unit 542. It is understood that those skilled in the art can set more power-receiving elements to share a single vibrating element to form multiple sets of transducer units. The two first coils 341 and 342 can be located on the same side of the magnet 44, or they can be located at opposite ends of the magnet 44. Optionally, the magnet 44 and the two first coils 341 and 342 can be arranged coaxially to facilitate balanced driving of the magnet 44. The number of turns, material, and magnetic gap between the two first coils 341 and 342 and the magnet 44 can be different, thus giving the two sets of transducer units 541 and 542 different frequency response characteristics. The controller 2 can send an electrical signal to one of the first coils to drive the magnet to vibrate based on the frequency band characteristics of the sound information. Specifically, controller 2 sends corresponding electrical signals to the transducer units whose frequency of resonance peak matches the frequency band characteristics of the sound information the most. Controller 2 can also send electrical signals to both first coils 341 and 342, causing magnet 44 to be driven by the superimposed alternating magnetic field generated by the two first coils 341 and 342, which can increase the amplitude of magnet 44 and thus increase the volume. Figure 4d The two sets of transducer units 541 and 542 can form a transducer unit pair. Those skilled in the art can set one or more such transducer units in the sound-generating component according to actual needs. Figure 4d The transducer pair shown.

[0128] Further optional, such as Figure 4eAs shown, the sound-generating component includes two diaphragms 451 and 452 and six piezoelectric elements 351, 352, 353, 354, 355, and 356. Three piezoelectric elements 351-353 are mechanically connected to different positions on diaphragm 451, and the other three piezoelectric elements 354-356 are mechanically connected to different positions on diaphragm 452; that is, the three piezoelectric elements share one diaphragm. Thus, the sound-generating component forms six sets of transducer units, namely transducer units 551-556. The diaphragm is connected to the housing 1. When the piezoelectric elements are excited by an electrical signal, they undergo mechanical deformation, causing the diaphragm to vibrate. The diaphragm then transmits the vibration signal to the housing 1. By changing the type of piezoelectric element, the connection position between the piezoelectric element and the diaphragm, and the size and material of the diaphragm, the frequency response characteristics of each set of transducer units can be adjusted. Figure 4e The frequency response characteristics of the six transducer units 551-556 in the sound source can be completely different, which can further broaden the frequency response range of the sound-generating component.

[0129] It is understood that the number of piezoelectric elements is not limited to three; that is, at least one piezoelectric element can be used. This application does not limit the position of the piezoelectric elements. Those skilled in the art can set the number of piezoelectric elements and the position of each piezoelectric element on the diaphragm according to the specific circumstances.

[0130] Furthermore, any of the bone conduction-based sound-emitting lollipops described above may also include a switching element. The user can input a switching signal through this element, which is then transmitted to the controller. The switching element can be implemented as a push-button switch, a toggle switch, or a sensor, such as a photosensor, temperature sensor, humidity sensor, voice sensor, capacitive sensor, or a combination of at least two of these. Specifically, when the user places the functional, ingestible portion of the device into their mouth, the photosensor detects the absence of ambient light, which is interpreted as triggering an on / off command. To prevent misjudgment when the device is held in the hand, temperature and humidity sensors can be added, as the oral cavity temperature is higher than the body surface temperature and the mouth is moist. The combination of these three factors allows for accurate determination of the user's on / off needs, thus achieving automatic on / off. The controller responds to the on / off signal sent by the switch by sending electrical signals to one or more corresponding transducer units.

[0131] Optionally, the bone conduction-based sound-generating lollipop of this embodiment may also include a power supply component, such as... Figure 2 and Figure 3The power supply 8 in the middle is used to power the controller and the sound-generating structure. The power supply component can be a replaceable dry cell battery or button cell battery, a rechargeable battery, or a supercapacitor, or a device that can convert mechanical energy into electrical energy through shaking or other movements, such as the structure in a mechanical watch that converts mechanical energy into electrical energy through the action of shaking the arm and gravity. It can also be a device that converts the mechanical energy of biting into electrical energy by creating a pressure difference in different parts of the semiconductor material through biting. It can also be a solar cell.

[0132] Optionally, the bone conduction-based sound-generating lollipop of this embodiment may also include at least one indicator light to indicate the working status of the bone conduction sound-generating device. For example, when the controller drives the sound-generating structure to generate a vibration signal, the indicator light illuminates, indicating that the sound-generating device is working normally. The working status of the bone conduction sound-generating device may include the working status of the sound-generating structure, the working status of the functional structure, and the power supply status. The indicator light can be placed in a non-accessible part of the bone conduction sound-generating device for easy observation of its operation, while also serving a decorative purpose and enhancing the user experience.

[0133] Optionally, the bone conduction sound-generating lollipop of this embodiment may further include at least one light-emitting device. When the sound-generating structure vibrates to transmit music signals, the controller changes the color or brightness of the light emitted by the light-emitting device according to the frequency changes of the sound source, or a combination of both—that is, changing both the brightness and the color of the light. The light-emitting device may also directly change the color or brightness of the light, or a combination of both, according to the intensity of the vibration of the sound-generating structure. This can enhance the cool appearance of the bone conduction sound-generating device and improve the user experience. Specifically, the light-emitting device may also flash according to a predetermined program. The light-emitting device can be installed in either the accessible or inaccessible part of the bone conduction sound-generating device. The light-emitting device can be a light-emitting appliance or light-emitting material suitable for installation on the bone conduction sound-generating device. Adding a light-emitting device can enhance the fun of the bone conduction sound-generating device.

[0134] It should also be noted that the outer shell 1 may be made of a material suitable for conducting vibration, or at least the portion of the outer shell 1 between the head 11 and the transducer unit and the head 11 should be made of a material suitable for conducting vibration signals, so as to reduce the attenuation of the vibration signal generated by the transducer unit during the transmission process.

[0135] The head 11 is shaped to fit into the mouth, such as a sphere, ellipsoid, or plate. The head 11 and other parts of the outer shell 1 that may be placed in the mouth should be made of non-toxic materials to avoid harming the user's health. Preferably, the entire outer shell 1 is made of non-toxic materials. The outer shell 1 may include one head 11 or multiple heads 11, which can contact different locations in the mouth to transmit vibration signals.

[0136] like Figure 2 and Figure 3 As shown, the outer casing 1 may further include a handle-like portion 12 connected to the head 11. A transducer unit can be disposed on the head 11 to reduce the attenuation of the vibration signal during transmission. A controller 2 can be disposed on the handle-like portion 12, which reduces the volume of the head 11, making it easier to place the head 11 into the mouth and improving safety during use. The handle-like portion 12 can be shaped to be easily gripped by the user, enhancing user comfort during use.

[0137] Furthermore, one or more hollow chambers 13 can be formed inside the outer shell 1, and the transducer unit and control system 2 can be disposed within the hollow chambers 13. When the lollipop based on bone conduction sound generation includes multiple sets of transducer units, the outer shell 1 can form multiple chambers 13, and different transducer units can be disposed within different chambers 13. For example... Figure 2 and Figure 3 As shown, the transducer unit and controller 2 can also be disposed in different chambers 13. The controller 2 can also be entirely encapsulated in the housing 1, for example, by injection molding to form the housing 1 outside the control system 2, so that the controller 2 is wrapped in the material of the housing 1 without forming a hollow chamber.

[0138] The bone conduction-based sound-generating lollipop provided in this embodiment includes a shell, a trigger, a controller, and a sound-generating component. The sound-generating component, controller, and trigger are integrated into the encapsulated cavity formed by the shell, eliminating the need for separate encapsulation of the sound-generating component. When the support portion of the shell enters the human mouth, the trigger sends an opening command to the controller, which drives the sound-generating component to vibrate. The vibration signal is transmitted to the human auditory system via bone conduction through the support portion of the shell and the edible material attached to the support portion, through the human oral tissue or teeth. Compared with existing bone conduction-based sound-generating lollipops, the elimination or reduction of the encapsulated shell of the traditional sound-generating structure makes the structure of the bone conduction sound-generating component simple and highly integrated, achieving miniaturization of the bone conduction-based sound-generating lollipop and reducing the sound quality loss of the device, thereby improving the sound quality.

[0139] Figure 5 This is a schematic diagram of a lollipop system based on bone conduction sound generation, provided as an embodiment of the present invention. Figure 5As shown, the bone conduction sound-generating lollipop system provided in this embodiment includes a bone conduction sound-generating lollipop 5_1 and a housing 5_2. The housing 5_2 loads and displays multiple sound-generating lollipops 5_1. A transmission device 5_3 is also provided inside the housing 5_2. The transmission device 5_3 is used to transmit the bone conduction sound-generating lollipop 5_1 from the housing 5_2 to the outlet 5_4 of the housing after the user purchases it. A control device is also provided in the housing 5_2. After receiving the user's purchase instruction, the control device sends a transmission instruction to the transmission device 5_3 to transmit the corresponding bone conduction sound-generating lollipop from the housing.

[0140] Optionally, the housing may have touch buttons or a touch screen such as an LCD screen or an LED screen. Users can press the button or touch the screen to select the type and quantity of bone conduction sound-emitting lollipops they wish to purchase. The control system will then send control signals to the transmission device according to these instructions.

[0141] Optionally, in another implementation, the user can scan a QR code using a smart terminal such as a mobile phone to enter the corresponding purchase page, select the bone conduction lollipop they want to buy, and make an online payment. Then, the control system sends a control signal to the transmission device based on the received purchase instruction.

[0142] Alternatively, users can also make the above purchases through a designated app.

[0143] In one possible implementation, users can also select or customize the bone conduction-based sound lollipop by burning personalized sound source data on the purchase page, including: songs from the song library provided by the service provider, sound data burned by the user, etc.

[0144] The acquisition of user-recorded audio data can be done by the user using a smart terminal, such as a mobile phone's recording function, or by using a recording device such as a microphone set in the housing. The user issues a recording command by clicking a button or tapping the screen, and then the control device receives the user's personalized recording from the microphone and stores the recording data in the memory of the lollipop based on bone conduction sound generation via wired / wireless means.

[0145] In this embodiment, the type and model of the lollipop purchased, or the sound source data stored in the lollipop based on bone conduction sound generation, can also be randomly assigned by the system. This makes the purchasing process more interesting, enhances the user experience, forms a model that combines purchasing and entertainment, increases the fun of purchasing, promotes user purchases, and thus increases the sales of lollipops based on bone conduction sound generation.

[0146] The bone conduction sound-generating lollipop system provided in this embodiment integrates bone conduction sound-generating lollipops into a human-computer interactive system. This allows for personalized sound source customization during the sales process, increasing the fun of the sales process, improving the user experience, and boosting sales of bone conduction sound-generating lollipops.

[0147] In addition to recording audio data, other information, such as electronic tickets, can also be recorded. When a user enters a location with the purchased lollipop, the identification chip embedded in the lollipop can establish a communication connection with an external device—the entry verification device. Then, RFID or other methods are used to verify the electronic ticket in the identification chip. This eliminates the need for a separate physical ticket, effectively increasing the lollipop's usage rate. It can be used not only to enjoy the lollipop while listening to the desired audio data but also as an entry pass.

[0148] Figure 6 This is a schematic diagram of a lollipop system based on bone conduction sound generation, provided as another embodiment of the present invention. Figure 6 As shown, the bone conduction-based sound-emitting lollipop system provided in this embodiment includes a bone conduction-based sound-emitting lollipop 6_1 and a housing 6_2. The housing 6_2 has a glass observation window on top and a joystick (shooting device) 6_6 below the observation window. Multiple sound-emitting lollipops 6_1 are displayed in multiple rows in the housing 6_2. A transmission device 6_3 is also provided inside the housing 6_2. The transmission device 6_3 is used to transmit the bone conduction-based sound-emitting lollipop 6_1 from the display shelf to the outlet 6_4 of the housing 6_2 after the user uses the joystick (shooting device) 6_6 to shoot it down. The control device sends a transmission command to the transmission device 6_3 after detecting that the sound-emitting lollipop 6_1 has fallen from the display shelf into the transmission device 6_3, thus transmitting the corresponding bone conduction-based sound-emitting lollipop out of the housing. In addition, a touch screen LCD screen 6_7, an earphone jack, a microphone 6_5, and a coin-operated change slot 6_8 are installed below the glass observation window.

[0149] Optionally, the housing may have touch buttons or a touch screen such as an LCD screen 6_7, allowing the user to press a button or touch the screen to control the shooting device 6_6 to shoot the desired bone conduction-based lollipop 6_1.

[0150] Optionally, after the user knocks down the bone conduction-based sound lollipop 6_1, the LCD screen 6_7 can display personalized settings prompts. The user can then record personalized voice using the microphone 6_5, or directly select music from the music library via the LCD screen 6_7, and transmit the music to the memory of the bone conduction-based sound lollipop 6_1 via the wired / wireless device of the bone conduction-based sound lollipop system.

[0151] Understandably, when using the device, users select products to purchase via the touchscreen, then use the microphone to record customized audio. They can plug in headphones to listen to the recorded audio, and once satisfied, complete the payment through the coin slot.

[0152] Optionally, after the bone conduction-based lollipop 6_1 is hit, it falls through a funnel onto a conveyor. A light sensor detects the product's passage and activates the delivery system. The product is then conveyed to a recording device, which uses NFC near-field communication to transmit data and record the user's audio into the product. After recording, the product is transported to a shipping device and dropped directly onto the shipping structure, allowing the user to take the product directly.

[0153] In this embodiment, the playback settings of the bone conduction sound-generating lollipop 6_1 are as follows: the recording is played first, followed by the music file. This fulfills the personalized customization requirement of putting the customized recording into the bone conduction sound-generating lollipop.

[0154] Figure 7 This is a schematic diagram of a lollipop system based on bone conduction sound generation, provided as another embodiment of the present invention. Figure 7 As shown, this embodiment describes a bone conduction-based lollipop device that allows users to select and personalize products using either a mobile phone or a touchscreen. The device includes: a bone conduction-based lollipop 7_1, a housing 7_2, an observation window, and a controller housed within the housing 7_2. The controller includes a user interaction system and a product delivery system. The controller's core circuitry includes an NB-IoT network interface and a network cable interface. The user interaction system includes: mobile phone operating software, a touchscreen operating system 7_7, a microphone 7_5, a directional speaker, and a barcode scanner 7_6. The product delivery system includes a storage device for the bone conduction-based lollipop 7_1, a sorting device, a conveying device, a programming device, a packaging device, and a shipping device.

[0155] On the left side, within the lower part of the observation window, products requiring charging are sorted and placed onto the charging station using a Type-C interface. Inside the outer casing 7_2, above the charging station within the observation window, a 3-axis robotic arm 7_3 is installed for product sorting. Outside the observation window, inside the outer casing 7_2, are the product packaging device, product shipping device, and core circuitry. The product programming device uses the Type-C interface of the product storage device. On the outside of the casing, to the right of the observation window, are a touchscreen, microphone, directional speaker, and barcode scanner.

[0156] Once the user selects a specific shape of the bone conduction sound-emitting lollipop 7_1 and completes the burning process, the robotic arm 7_3 directly removes the product based on its position in the storage device, places it on the product packaging device, and packages it using mechanical folding. The robotic arm of the product shipping device then delivers the packaged bone conduction sound-emitting lollipop 7_1 through the conveyor 7_4 out of the outer casing 7_2, presenting it to the user.

[0157] In use, the user first selects the shape of the bone conduction-based lollipop 7_1 and background music on the touchscreen 7_7. Then, the user uses the microphone 7_5 on the device to record customized audio and completes the mixing process via the touchscreen. Through the directional speaker, the user can preview the recording, music, and mixed audio. Once satisfied, the user scans the QR code 7_6 with their mobile phone to pay, and the touchscreen 7_7 notifies the device that payment has been made. The device connects to the internet via a network cable to confirm payment information.

[0158] Optionally, users can also complete the above operations via a smart terminal such as a mobile phone. The difference is that before use, the user needs to connect to the internet via the smart terminal, using methods such as Wi-Fi, Bluetooth, or 5G communication. Alternatively, the operation can be performed through dedicated software on the smart terminal. Then, the user uses the smart terminal's microphone to record customized audio and completes the mixing process through the smart terminal's interface. Using the smart terminal's player, the user can preview the recording, music, and mixed audio. Once satisfied, the user uses the smart terminal to make online payment and informs the device that payment has been made. The device connects to the internet via a network cable to confirm the payment information.

[0159] After confirmation, the burning device uses the TYPE-C interface to burn the generated mixed file into the bone conduction sound-generating lollipop 7_1. Once burning is complete, based on the position of the bone conduction sound-generating lollipop 7_1 in the storage device, the robotic arm directly removes the product and places it on the product packaging device. The product is then packaged using a mechanically folded cardboard box. Finally, the robotic arm of the product shipping device sends the packaged bone conduction sound-generating lollipop 7_1 out of the outer casing 7_2 through the transmission port 7_4, presenting it to the user, who can then directly take the product.

[0160] The bone conduction sound-generating lollipop systems described in the two embodiments above provide a human-computer interaction vending machine with personalized recording capabilities. By fully utilizing the memory of the bone conduction sound-generating lollipop to store sound sources and the ability to transmit data via an external interface, users can purchase bone conduction sound-generating lollipops in various interactive and fun ways, enriching the sales experience and increasing sales of bone conduction sound-generating lollipops.

[0161] Figure 8 This is a flowchart illustrating a method for processing lollipops based on bone conduction sound generation, as provided in one embodiment of the present invention. Figure 8 As shown, the method includes:

[0162] S101. The controller receives the start command through a trigger, or determines whether the lollipop has entered the mouth of the object to be transmitted sound or touched the teeth through a trigger.

[0163] S102. When the controller determines that it has received the opening command, or when the controller determines through the trigger that the lollipop has entered the oral cavity of the object to be transmitted sound or has touched the teeth, the controller drives the sound-generating component to generate a vibration signal, so as to transmit the vibration signal to the auditory system of the object to be transmitted sound through at least one support and the lollipop.

[0164] In this embodiment, the method can be applied to the above. Figure 1 The lollipop based on bone conduction sound generation shown is similar in principle and technical effect, and will not be elaborated here.

[0165] Optionally, in order to allow users to listen to music or stories while enjoying lollipops, and considering that the music or stories can be played continuously even when the lollipop is frequently in and out of the mouth, the present invention also provides the following preferred embodiment:

[0166] In one possible design, when the sensor includes a pressure sensor, the controller triggers the sound-generating component to generate a vibration signal based on the pressure change sensed by the pressure sensor when the lollipop is touched.
