Description

Technical Field

[0002] Bone conduction is a method of sound conduction, which converts sound into mechanical vibrations of different frequencies, transmits the vibration waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, auditory nerve, and auditory center, and finally obtains sound information through the perception of the cerebral cortex.

[0003] Unlike air conduction, which transmits sound through air vibration, traditional bone conduction devices transmit sound mainly through squeezing contact with the user's body surface, such as by wearing components pressed against the temples, forehead, etc. Contact with the body surface will cause the following problems: First, long-term use of the surface of the bone conduction device, especially the place in contact with the body surface, will have a large number of bacteria, which will cause hygiene and health problems; second, the contact part is integrated with the device and cannot be replaced; third, it cannot be shared by multiple users or reused, that is, the utilization rate between different users is low.

[0004] In addition, most existing bone conduction devices transmit sound by vibrating on the body surface, which will cause the air around the device to vibrate and cause sound leakage. The sound leakage will affect the sound quality actually received by the user and is not conducive to protecting the user's privacy. Summary of the invention

These drawings and text descriptions are not intended to limit the scope of the present invention in any way, but to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein, for example, can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0048] The following specific embodiments are used to describe in detail the technical solutions of the present invention and how the technical solutions of the present application solve the above-mentioned technical problems. The following 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 be described below in conjunction with the accompanying drawings.

[0049] In the prior art, bone conduction devices are usually worn behind the ears, temples, forehead, etc., and pressed against the body surface to transmit vibrations to the skin tissue, muscle tissue, bones, and finally the auditory system. However, this wearing method is not convenient for users to fix the position of the bone conduction sound-generating device when using it. In addition, in order to ensure a certain sound quality, the bone conduction device and the fitting part need to be tightly pressed and fitted, which brings a certain sense of oppression to users when using it.

[0050] The contact between bone conduction devices and the body surface will also cause the following problems: first, long-term use of the surface of the bone conduction device, especially the place where it contacts the body surface, will be filled with a large number of bacteria, which will lead to hygiene and health problems; second, the contact part is integrated with the device and cannot be replaced; third, it cannot be shared by multiple users or reused, that is, the utilization rate between different users is low.

[0051] In addition, most existing bone conduction devices transmit sound by vibrating on the body surface, which will cause the air around the device to vibrate and cause sound leakage. The sound leakage will affect the sound quality actually received by the user and is not conducive to protecting the user's privacy.

[0052] In addition, the bone conduction sound-generating devices in the prior art also have defects such as a narrow frequency range, which leads to poor sound quality. Although the sound quality can be improved by setting up multiple bone conduction sound-generating devices, the number, volume and weight of the required devices will be greatly increased, which will further lead to inconvenience and oppression when wearing. In addition, especially when the bone conduction device is worn behind the user's ears, temples, forehead and other parts, it will also be limited by the use of space, that is, the sound quality cannot be improved by increasing the number of devices.

[0053] Based on the above technical problems, this embodiment provides a bone conduction-based clamping device, including a handle, a clamping structure arranged on one side of the handle, and a sound processor arranged inside the handle. The clamping structure clamps food, and the user puts the food into the mouth. The vibration signal generated by the sound processor is transmitted to the food through the clamping structure and then to the auditory system through the oral tissue or teeth of the user, thereby avoiding the pressure of squeezing and wearing. Putting it into the mouth can also reduce sound leakage, improve sound quality and protect privacy. In addition, the clamping structure can also be used to replace food, ensuring hygiene and health, and can improve the utilization rate of the device, and can also realize multi-user sharing, achieving energy-saving and environmental protection effects.

[0054] Figure 1 Schematic diagram of the structure of the bone conduction-based clamping device provided by an embodiment of the present invention. Figure 1 As shown, the bone conduction-based clamping device of this embodiment includes: a handle 1, at least one clamping structure 12 arranged on one side of the handle 1, and a sound processor arranged inside the handle. The sound processor includes: at least one controller 2 and at least one sounding member 5.

[0055] The controller 2 can be used to control the clamping structure 12 to clamp the food 7. When the food 7 enters the user's mouth, or the user holds or bites the food 7, the controller 2 detects this state and then drives the sound-generating component 5 to generate a vibration signal. The vibration signal can be transmitted to the clamping structure 12 through the handle 1 connected to the sound-generating component, and then transmitted to the food 7, and finally transmitted to the user's auditory system through the inside of the mouth or tooth contact.

[0056] The food 7 includes candies, chocolates, teething sticks, meat jerky and the like, and may also be medicines, and the food 7 may also be composed of two or more different edibles.

[0057] In a possible embodiment, the food 7 includes an outer layer and an inner layer, and the outer layer covers the outer side of the inner layer. The inner layer can be a liquid material, such as liquid syrup or other liquid edibles, and the outer layer can be a rigid material or a hard gelatin material, which is suitable for contacting with teeth to transmit vibration signals and prevent the liquid inner layer from flowing out. The liquid material of the inner layer includes a solution, a suspension and an emulsion.

[0058] Optionally, the food 7 is a rigid material or a colloid material with high hardness, which is suitable for conducting vibration signals. The colloid material refers to a semi-solid gel material that can maintain a certain shape, such as agar.

[0059] Optionally, food 7 represents an object that can enter the oral cavity, ear canal or nasal cavity, and the material of food 7 is healthy material that can ensure the health of the user.

[0060] In this embodiment, by replacing the food 7, it is possible to ensure that the food 7 that the user contacts is clean and hygienic, and after the food 7 is used, the handle 1 can also clamp other forms of food 7 through the clamping structure 12, thereby improving the utilization rate of the handle 1, and the food 7 can be made into various shapes, such as various shapes of lollipops, or various shapes of medicines, so that the user can have a variety of choices and choose according to their own interests or purposes. For example, if a child does not want to take medicine, then this cartoon-shaped medicine can be used to attract the child to take medicine. For another example, if the food 7 is a lollipop of different shapes, the user can choose different shapes according to his or her preferences, thereby improving the user experience. And by replacing the food 7 through the clamping structure 12, one handle 1 can also be used by multiple users in turn, thereby improving the utilization rate of the clamping device of this embodiment among different users.

[0061] It should be noted that the user mentioned in this embodiment can be a human or other animals with an oral cavity, such as a puppy or a kitten. This embodiment does not limit the user. In this embodiment and subsequent examples, the bone conduction sound entertainment device is mainly used on humans as an example for detailed description.

[0062] This embodiment provides a bone conduction-based clamping device, including a handle, a clamping structure arranged on one side of the handle, and a sound processor arranged inside the handle. The clamping structure clamps food, and the user puts the food into the mouth. The vibration signal generated by the sound processor is transmitted to the food through the clamping structure and then to the auditory system through the oral tissue or teeth of the user, thereby avoiding the pressure of squeezing and wearing. Putting it into the mouth can also reduce sound leakage, improve sound quality and protect privacy. The clamping structure can also be used to replace food, ensuring hygiene and health, and can improve the utilization rate of the device, and can also realize multi-user sharing, achieving energy-saving and environmental protection effects.

[0063] Figure 2 The structure diagram of the bone-transmitted clamping device provided by one embodiment of the present invention is shown in FIG. Figure 2As shown, in this embodiment, the handle 1 includes a main body 120 and at least one clamping structure 12 connected to the main body 120, and the clamping structure 12 can be detachably connected to the food 7 to fix the food 7. The sound-generating member 5 and the controller 2 are arranged in the main body 120 and connected by a wire. The sound-generating member 5 includes at least one power receiving element 3 and at least one vibration element 4. The vibration element 4 is mechanically connected to the clamping structure 12 of the handle 1, and the control system 2 is electrically connected to the power receiving element 3 and transmits an electrical signal containing sound information to at least one power receiving element 3. The power receiving element 3 is excited by the electrical signal and drives the vibration element 4 to generate a vibration signal. The vibration signal is transmitted to the food 7 via the clamping structure 12 of the handle 1, and the vibration signal is suitable for being transmitted to the auditory system by bone conduction. After the clamping structure 12 is connected to the food 7, when the food 7 contacts the mouth, the vibration signal is transmitted to the auditory system by bone conduction via the handle 1 and the food 7. When the handle 1 directly contacts the mouth, the vibration signal can also be transmitted to the auditory system by bone conduction via the handle 1.

[0064] In this embodiment, the clamping structure 12 includes: at least one clamping nut 121a and at least one clamping claw 121b. Figure 2 As shown, the connection end 71 of the food 7 is inserted into the accommodating space formed by the clamping grasping 121b, the outer side surface of the clamping grasping 121b may have an external thread, and the clamping nut 121a may have a corresponding internal thread, and the clamping nut 121a and the clamping grasping 121b are connected by threads.

[0065] Optionally, the clamping nut 121a and the clamping grip 121b may also be connected by interference fit, or may be connected by a plug-in structure clamping or other methods without providing threads.

[0066] When the clamping nut 121a is not connected to the clamping claw 121b, the clamping claw 121b is in a natural state, and the accommodation space formed by the clamping claw 121b is the largest, which can allow the connection end 71 to pass through; when the clamping nut 121a is connected to the clamping claw 121b, the clamping claw 121b elastically deforms to reduce the accommodation space, thereby clamping the connection end 71. When the food 7 needs to be removed, the clamping nut 121a can be separated from the clamping claw 121b, and the connection end 71 can be smoothly removed from the fixing device.

[0067] It should be noted that the difference between the sound-emitting component 5 of this embodiment and the sound-emitting component in the traditional bone conduction sound-emitting device is that the traditional sound-emitting component has an independent shell that encapsulates the sound-emitting component. The existing technical means to improve the sound quality of the bone conduction sound-emitting device is to increase the number of sound-emitting components in different frequency domains, but the traditional sound-emitting components are individually encapsulated, which increases the volume and weight occupied by the shell geometrically, and the production cost also increases accordingly. In addition, the encapsulated shell increases the transmission distance of the vibration, causing the vibration signal to attenuate, which causes the sound quality to be lost.

[0068] The inventors of the present application have found through creative exploration in practice that the packaging of the sound-generating component 5 can be a package in which multiple vibration actuators are integrated together, that is, multiple power receiving elements 3 and multiple vibration elements 4 are integrated together, or the packaging can be realized by relying on the handle 1 of the clamping device based on bone conduction, that is, the sound-generating component 5 is embedded in the cavity 13 formed by the handle 1, or the handle 1 wraps the sound-generating component 5; the packaging of the sound-generating component 5 can also be shared with the controller 2, such as Figure 2 As shown, the sound-generating component 5 is integrated with the controller 2; the sound-generating component 5 can also be packaged as a whole with the controller 2 and the handle 1, such as Figure 2 As shown, the three are integrated into the cavity 13 formed by the outer shell of the handle 1.

[0069] Optionally, the bone conduction-based clamping device of this embodiment may further include a power supply component, such as Figure 2 The power supply 8 is used to supply power to the controller and the sound-generating component. The power supply component may be a replaceable dry cell or button cell, a rechargeable battery, or a super capacitor, or a device that can convert mechanical energy into electrical energy through movements such as shaking, such as a structure in a mechanical watch that converts mechanical energy into electrical energy through shaking of the arm and the action of gravity. It may also be a device that converts bite mechanical energy into electrical energy by causing a pressure difference to form at different parts of a semiconductor material through biting, or it may be a solar cell.

[0070] Optionally, the bone conduction-based clamping device of this embodiment may further include a switch element 81 mounted on the handle 1, and the user may input a switch signal through the switch element 81 and transmit the signal to the controller 2. The switch element 81 may be implemented as a button switch, or a toggle switch, or a sensor, such as a photosensitive sensor, a temperature sensor, a humidity sensor, a voice-controlled sensor, a capacitive sensor, or a combination of at least two of them. Specifically, when the user holds the handle 1 in his hand, the temperature sensor detects that the temperature of the handle 1 has risen, which can be considered to have triggered an opening instruction. The controller 2 sends an electrical signal to one or more sound-emitting components 5 in response to the opening signal sent by the switch element 81.

[0071] Optionally, the bone conduction-based clamping device of this embodiment also includes a communication interface 82, which is used to receive sound information sent by an external device in a wired and / or wireless manner. The control system can convert the sound information sent by the external device into a corresponding electrical signal and transmit it to the corresponding sound-emitting component 5, thereby driving the sound-emitting component 5 to vibrate.

[0072] Among them, the communication interface 82 includes USB interface, eSATA interface, SD card interface, Micro SD card interface, audio input interface, video input interface, Wi-Fi interface, Bluetooth interface, metal electrodes, microphones and other interfaces suitable for receiving electrical signals, radio waves, magnetic signals, optical signals and the like containing sound information; the communication interface 82 may include one of the above interfaces, or it may be a combination of multiple interfaces.

[0073] Optionally, the controller 2 can also match the corresponding sound source, such as a specific ringtone, according to the food type given by the food selection button set on the handle; or through the sensor set on the clamping device, such as a pressure sensor, the material of the food can be judged according to the clamping force given by the sensor. For example, there is a corresponding relationship between the hardness or weight of the food and the clamping force, and different sound sources can be matched according to different materials. It can be understood that the method for determining the food type is not limited to the above method, and the present invention does not limit the method for determining the food type. Those skilled in the art can select a specific solution to implement it according to actual conditions.

[0074] This embodiment provides a bone conduction-based clamping device, including a handle, a clamping structure arranged on one side of the handle, and a sound processor arranged inside the handle. The clamping structure clamps food, and the user puts the food into the mouth. The vibration signal generated by the sound processor is transmitted to the food through the clamping structure and then to the auditory system through the oral tissue or teeth of the user, thereby avoiding the pressure of squeezing and wearing. Putting it into the mouth can also reduce sound leakage, improve sound quality and protect privacy. The clamping structure can also be used to replace food, ensuring hygiene and health, and can improve the utilization rate of the device, and can also realize multi-user sharing, achieving energy-saving and environmental protection effects.

[0075] Figure 3 This is a schematic diagram of the structure of a bone conduction-based clamping device provided by another embodiment of the present invention. Figure 3 As shown, the bone conduction-based clamping device of this embodiment includes: a handle 1, at least one clamping structure 12 arranged on one side of the handle 1, and a sound processor arranged inside the handle. The sound processor includes: at least one controller 2 and at least one sounding member 5.

[0076] In this embodiment, the handle 1 includes: at least one head 11, at least one connecting section 14 and a tail end 15. The sound-generating component 5 is encapsulated in the cavity of the head 11 and connected to the head 11. When the sound-generating component 5 vibrates, the vibration signal is transmitted to the head 11, and then transmitted to the clamping structure 12 and the food 7 by the head 11. The two ends of the connecting section 14 are respectively connected to the head 11 and the tail end 15. The connecting section 14 can be made into different lengths or a structure with adjustable length. Those skilled in the art can determine the length and specific shape of the connecting section 14 according to actual conditions, and this embodiment does not limit it. The connecting section 14 can also include vibration isolation materials to prevent the vibration from being transmitted to the tail end 11 to affect the grip, and can reduce sound leakage.

[0077] In this embodiment, the clamping structure 12 is an elastic clamping structure 122, which is made of elastic material, such as rubber, silicone and other materials, and has a fixing hole corresponding to the shape of the connecting end 71 of the food 7. Taking the connecting end 71 as a cylindrical body as an example, the fixing hole can be a circular hole. When the fixing hole is in a natural state, the inner diameter is smaller than the diameter of the connecting end 71. The end of the fixing hole away from the head 11 can have a rounded or chamfered corner to facilitate the connecting end 71 to enter the fixing hole. Since the elastic clamping structure 122 is elastic, the connecting end 71 can smoothly enter the fixing hole, the inner diameter of the fixing hole becomes larger, and pressure is applied to the connecting end 71, so that the connecting end 71 is fixed in the fixing hole. When the food 7 needs to be removed, the user uses a larger pulling force to overcome the friction of the inner wall of the fixing hole on the connecting end 71, and the connecting end 71 can be pulled out of the fixing hole. Optionally, the head 11 and the elastic clamping structure 122 can be integrated, which can improve the overall strength of the bone conduction sound-generating device.

[0078] The implementation methods of other structures of this embodiment are Figure 2 The embodiments shown are similar and will not be described again here.

[0079] Optionally, the controller 2 can also determine the type of user corresponding to the oral cavity according to the size of the teeth in the oral cavity obtained at the entrance, and determine the sound source that matches the type of the user, as well as the size of the playback volume. Specifically, a micro camera is provided in the head 11. When the user opens his mouth, the micro camera collects a picture of the teeth in the user's oral cavity. The controller 2 analyzes the size of the teeth in the collected picture (including: tooth shape and / or appearance characteristics), and can match it according to the user type pre-stored in the controller 2. The type of user can be determined. For example, if it is the size of a child's teeth, music suitable for children can be selected, and because children have sensitive hearing, it is necessary to select the volume of the music accordingly and adjust it to an appropriate volume. Then, when the controller 2 detects that the clamping structure puts food into the user's mouth, it can drive the sound structure 5 to generate a corresponding vibration signal according to the previously determined sound source and the corresponding playback volume.

[0080] Furthermore, in a possible implementation, when the user has finished eating the food, or there is no food in the clamping structure, the user directly puts the clamping structure into the mouth, or bites the clamping structure. At this time, the controller detects that there is no food in the clamping structure through a sensor such as a pressure sensor, but detects that the user is using the clamping device or has put it in the mouth through another sensor or switch element. Then the controller 2 stops driving the sound-making component 5 to make a sound, and starts a timer or a timing program in the controller 2 to record the time length for which the user puts all or part of the clamping structure in the mouth. When the time length is greater than a preset time length threshold, for example 20 seconds, it is determined that the user wishes to continue using the bone conduction-based clamping structure to listen to the sound source information, and the controller re-drives the sound-making component 5 to generate a vibration signal; if the time length is less than or equal to the preset time length threshold, it is considered that the user does not want to continue using it, and the controller 2 no longer re-drives the sound-making component 5 to work.

[0081] Optionally, in a possible implementation, the tail end 15 further includes an indicator light 83 for indicating the working state of the bone conduction-based clamping device. The working state of the bone conduction-based clamping device may include the working state of the sound-generating component, the power state of the power source 8, the indication state of whether the food is ingested, etc. The indicator light may also be provided at the connecting section 14 or the head 11 for the convenience of the user to observe.

[0082] This embodiment provides a bone conduction-based clamping device, including a handle, a clamping structure arranged on one side of the handle, and a sound processor arranged inside the handle. The clamping structure clamps food, and the user puts the food into the mouth. The vibration signal generated by the sound processor is transmitted to the food through the clamping structure and then to the auditory system through the oral tissue or teeth of the user, thereby avoiding the pressure of squeezing and wearing. Putting it into the mouth can also reduce sound leakage, improve sound quality and protect privacy. The clamping structure can also be used to replace food, ensuring hygiene and health, and can improve the utilization rate of the device, and can also realize multi-user sharing, achieving energy-saving and environmental protection effects.

[0083] Figure 4 This is a schematic diagram of the structure of a bone conduction-based clamping device provided by another embodiment of the present invention. Figure 4 As shown, the bone conduction-based clamping device of this embodiment includes: a handle 1, at least one clamping structure 12 arranged on one side of the handle 1, and a sound processor arranged inside the handle. The sound processor includes: at least one controller 2 and at least one sounding member 5.

[0084] like Figure 4As shown, in this embodiment, the clamping structure 12 includes at least one clamping arm 123 and at least one elastic member (not shown in the figure), and the clamping arm is rotatably connected to the head 11; and when there are more than one clamping arm 123, each clamping arm 123 can rotate relatively, and each clamping arm 123 can be connected to the head 11 through a separate rotating shaft, or can be connected to the head 11 through the same rotating shaft.

[0085] In this embodiment, the controller 2 may also include a memory, and the sound source information may be pre-stored in the memory. The controller 2 converts the pre-stored sound source information into a corresponding electrical signal and transmits it to the corresponding sound-generating member 5. The memory may be any device suitable for storing information and facilitating the control system to obtain information, including a semiconductor memory, a magnetic surface memory, etc. The elastic member may connect multiple clamp arms 123, or multiple groups of elastic members may be provided, each of which is connected to a portion of the clamp arms 123, each elastic member is connected to at least one clamp arm 123, and the elastic member may be a tension spring, a torsion spring, or other forms of elastic connectors. When the clamp arm 123 is in the clamping position, the opening formed by the clamping end of the clamp arm is smaller, thereby clamping the connecting end 71 of the food 7; when the user presses the pressing end of the clamp arm, so that the clamp arm 123 is in the release position, the opening formed by the clamping end of the clamp arm becomes larger, so that the connecting end 71 of the food 7 can pass through. Due to the action of the elastic element, the clamp arm 123 is in a clamping state when there is no external force pressing the pressing end.

[0086] Optionally, the controller 2 may also control the release or clamping state of the clamping arm by controlling the rotation axis of the clamping arm.

[0087] Optionally, in this embodiment, the controller 2 may further include a microphone 21 for collecting the user's voice input. The controller 2 may store the input voice in a memory to facilitate the user's personalized customization needs. For example, parents may enter a blessing message, and when the child takes the clamping device, the blessing message will be automatically played.

[0088] Optionally, the controller 2 may further include an identification chip for establishing a communication connection with an external device and performing verification interaction processing with the external device.

[0089] In this example, when the user enters a place with the purchased lollipop, a communication connection can be established with an external device, i.e., a verification device for entering the place, through the identification chip set in the lollipop, and then the electronic ticket in the identification chip is verified using RFID (Radio Frequency Identification) technology or other methods, so that the user does not need to hold a ticket separately, thereby effectively improving the usage rate of the lollipop, that is, it can not only be used to taste and listen to the sound data required by the user, but also can be used as a credential for entry and exit.

[0090] This embodiment provides a bone conduction-based clamping device, including a handle, a clamping structure arranged on one side of the handle, and a sound processor arranged inside the handle. The clamping structure clamps food, and the user puts the food into the mouth. The vibration signal generated by the sound processor is transmitted to the food through the clamping structure and then to the auditory system through the oral tissue or teeth of the user, thereby avoiding the pressure of squeezing and wearing. Putting it into the mouth can also reduce sound leakage, improve sound quality and protect privacy. The clamping structure can also be used to replace food, ensuring hygiene and health, and can improve the utilization rate of the device, and can also realize multi-user sharing, achieving energy-saving and environmental protection effects.

[0091] The inventor of the present invention has also made an integrated improvement to the bone conduction sound-generating component 5, by increasing the number of power receiving elements and vibration elements in the bone conduction sound-generating component, so that the frequency response range of the bone conduction sound-generating component can be expanded, thereby improving the sound quality of the bone conduction sound-generating component. Specifically, the packaging form of the sound-generating component 5 can be a plurality of vibration actuators integrated together to achieve packaging by relying on the handle 1. Through this integrated method, it is possible to eliminate the independent packaging shell of the traditional bone conduction sound-generating component, reduce the volume and weight of the clamping device, avoid increasing the sound quality by adding sound-generating component elements, and achieve a substantial reduction in the production cost of the bone conduction device. Eliminating the independent packaging shell of the sound-generating component can also reduce the sound quality loss caused by the shell.

[0092] The sound-generating component 5 in the above-mentioned embodiment of the present invention can be implemented in many ways. The structure of the sound-generating component 5 is described in detail below.

[0093] Figures 5a to 5e Schematic diagram of the structures of various sound-generating components of the bone conduction-based clamping device provided in various embodiments of the present invention. Figures 5a to 5e A schematic diagram of the structure of various sound-generating components of a bone-conducting clamping device provided in an embodiment of the present invention;

[0094] like Figure 5a As shown, in an optional embodiment, the sound-generating component 5 includes at least one power receiving element and at least one vibration element. Figure 5a The power receiving element is the first coil 31, and the vibration element is the magnet 41, but the specific forms of the power receiving element and the vibration element are not limited thereto.

[0095] It should be noted that the magnet 41 of the present embodiment may also be a magnet composed of a coil, or a magnet composed of a coil and a magnet. Similarly, the first coil 31 may also be a magnet composed of a coil and / or a magnet. In the present application, a magnet refers to a component that can generate a magnetic field or a structural module that can generate a magnetic field. The magnets and coils mentioned in the following embodiments may have similar implementations, which are explained here and will not be repeated below. The present invention does not limit the specific form of the magnet, and all components that can generate a magnetic field fall within the scope of the magnet described in the present invention.

[0096] The first coil 31 and the magnet 41 form a group of transducer units 51, and the transducer units 51 generate vibration signals according to the electrical signals sent by the controller 2. When the power receiving element and the vibration element are both certain elements, the frequency response characteristics of the transducer unit 51 are determined accordingly, and the sound-emitting component 5 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 acts magnetically with the magnet 41, so that the magnet 41 applies pressure to the head 11 through a mechanical connection, causing the head 11 to deform. The strength of the magnetic field is adjusted by the electrical signal, and the deformation amount is changed accordingly, so that the head 11 vibrates together with the magnet 41, thereby realizing the conversion of the electrical signal sent by the controller 2 into a vibration signal carrying sound information, that is, realizing vibration sounding.

[0097] Optionally, the transducer unit 51 may also include at least one elastic structure or elastic element 6 connected to the head 11 to transmit the vibration signal generated by the vibration element to the head 11. The elastic element or elastic structure 6 includes a spring, a rubber block, 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.

[0098] Figure 5b to Figure 5e They are schematic diagrams of the structures of the second to fifth transducer units of this embodiment. Figure 5b to Figure 5eAs shown, in another optional embodiment, the sound-generating member 5 includes at least two power receiving elements and / or at least two vibration elements, whereby the power receiving elements and the vibration elements form at least two groups of transducer units, and each transducer unit is used to generate a corresponding vibration signal in response to the electrical signal sent by the controller 2. When the transducer unit includes at least two power receiving elements and the power receiving element is a first coil, the multiple first coils can be arranged coaxially, arranged side by side, or arranged in other ways. In each transducer unit, if there are multiple groups of vibration groups formed by magnets and coils, each vibration group can have different frequency response characteristics. Further optionally, each group of transducer units can have the same frequency response characteristics or different frequency response characteristics. When multiple transducer units have more than two frequency response characteristics, the control system can drive different transducer units to work with different frequency response curves, thereby selecting one or more groups of transducer units with specific frequency response characteristics to vibrate according to specific circumstances, which can significantly improve the sound quality.

[0099] like Figure 5b As shown, in an optional embodiment, the number of power receiving elements and vibration elements is the same, the power receiving elements correspond to the vibration elements one by one, each power receiving element is electrically connected to the control system 2 and drives a corresponding vibration element to vibrate, thereby forming multiple groups of transducer units. Figure 5b The lollipop based on bone conduction sound generation shown includes two power receiving elements and two vibration elements, forming two groups of transducer units, namely transducer unit 521 and transducer unit 522. The frequency response characteristics of multiple groups of transducer units can be different. The controller 2 can drive one or several groups of transducer units corresponding to the frequency response characteristics to vibrate according to the frequency band characteristics of the sound information. Specifically, the controller 2 sends corresponding electrical signals to one or several groups of transducer units whose frequency of the resonance peak matches the frequency band characteristics of the sound information the most. Figure 5b In the embodiment, the power receiving elements are the first coil 321 and the first coil 322, and the vibration elements are the magnet 421 and the magnet 422, but the specific forms of the power receiving elements and the vibration elements are not limited thereto.

[0100] In another optional embodiment, if Figure 5c As shown, the sound-generating component includes at least two vibration elements and forms at least two groups of transducer units, and at least two groups of transducer units have a common power receiving element, that is, at least one power receiving element can drive more than two different vibration elements. Figure 5c In the embodiment, the power receiving element is the first coil and the vibration element is the magnet. Of course, the power receiving element and the vibration element may also be other elements. Figure 5cAs shown, the sound-generating component includes a first coil 33 and two magnets 431 and 432. The two magnets 431 and 432 are respectively arranged on both sides of the first coil 33, and the two magnets 431 and 432 are both within the effective action range of the magnetic field generated by the first coil 33, that is, the first coil 33 can drive both the magnet 431 and the magnet 432, thereby forming two groups of transducer units, namely, the transducer unit 531 and the transducer unit 532. Of course, the two magnets 431 and 432 can also be arranged on the same side of the first coil 33. The weight, size, material, and magnetic air gap between the two magnets 431 and 432 and the first coil 33 can be different, thereby, the two groups of transducer units 531 and 532 have different frequency response characteristics. When the controller 2 sends an electrical signal to the first coil 33, the two magnets 431 and 432 are driven to vibrate, so that the vibration signal output by the lollipop based on bone conduction sound is the superposition effect of the two groups of transducer units 531 and 532, thereby improving the sound quality of the lollipop based on bone conduction sound and reducing the overall volume of the sound module. Figure 5c The two groups of transducer units 531 and 532 in the figure can form a transducer unit pair. Those skilled in the art can set one or more transducer units in the sound-generating component according to actual needs. Figure 5c The pair of transducer units shown in .

[0101] In another optional embodiment, if Figure 5d and Figure 5e As shown, the sound module includes at least two power receiving elements and forms at least two groups of transducer units, and at least two groups of transducer units have a common vibration element, that is, at least one vibration element can be driven to vibrate by at least two power receiving elements respectively, thereby reducing the overall volume of the sound module. Figure 5d In the embodiment, the power receiving element is the first coil and the vibrating element is the magnet. Figure 5e In the embodiment, the power receiving element is a piezoelectric sheet and the vibration element is a diaphragm. It can be understood that the power receiving element and the vibration element can also be other elements.

[0102] Further optionally, if Figure 5dAs shown, the sound-generating member includes two first coils 341, 342 and a magnet 44, and the magnet 44 is within the effective range of the magnetic field generated by the two first coils 341, 342, that is, the magnet 44 can be driven by both the first coil 341 and the first coil 342, thereby forming two groups of transducer units, namely, transducer unit 541 and transducer unit 542. It can be understood that those skilled in the art can set more power receiving elements to share a vibration element to form multiple groups of transducer units. The two first coils 341, 342 can be arranged on the same side of the magnet 44, or can be arranged at both ends of the magnet 44 respectively. Optionally, the magnet 44 and the two first coils 341, 342 are coaxially arranged to facilitate balanced driving of the magnet 44. The number of turns, materials and magnetic air gaps of the two first coils 341, 342 and the magnet 44 can be different, thereby, the two groups of transducer units 541, 542 have different frequency response characteristics. The controller 2 can send an electrical signal to one of the first coils to drive the magnet to vibrate according to the frequency band characteristics of the sound information. Specifically, the controller 2 sends a corresponding electrical signal to a group of transducer units whose frequency of the resonance peak matches the frequency band characteristics of the sound information the most. The controller 2 can also send electrical signals to both first coils 341 and 342, so that the magnet 44 is driven by the superimposed alternating magnetic field generated by the two first coils 341 and 342, which can increase the amplitude of the magnet 44 and thus increase the volume. Figure 5d The two groups of transducer units 541 and 542 in the figure can form a transducer unit pair. Those skilled in the art can set one or more transducer units in the sound-generating component according to actual needs. Figure 5d The pair of transducer units shown in .

[0103] Further optionally, if Figure 5e As shown, the sound-generating component includes two diaphragms 451, 452 and six piezoelectric sheets 351, 352, 353, 354, 355, 356, of which three piezoelectric sheets 351-353 are mechanically connected to different positions on the diaphragm 451, and the other three piezoelectric sheets 354-356 are mechanically connected to different positions on another diaphragm 452, that is, the three piezoelectric sheets share one diaphragm. Thus, the sound-generating component 5 forms six groups of transducer units, namely transducer units 551-556. The diaphragm is connected to the handle 1, and the piezoelectric sheet is stimulated by the electrical signal to generate mechanical deformation, which drives the diaphragm to generate a vibration signal, and the diaphragm transmits the vibration signal to the handle 1. The frequency response characteristics of each group of transducer units can be adjusted by changing the model of the piezoelectric sheet, the connection position between the piezoelectric sheet and the diaphragm, and the size and material of the diaphragm. Figure 5e The frequency response characteristics of the six groups of transducer units 551-556 can be completely different, thereby further broadening the frequency response range of the sound module.

[0104] It can be understood that the number of the above-mentioned piezoelectric sheets is not limited to three, that is, the piezoelectric sheet can be set to at least one, and the present application does not limit the position of the piezoelectric sheet. Technical personnel in this field can set the number of piezoelectric sheets and the position of each piezoelectric sheet on the diaphragm according to specific circumstances.

[0105] The above-mentioned embodiments cancel the separate packaging of the sound-emitting component, so that the design structure of the bone conduction sound-emitting component is simple and highly integrated, the audio frequency domain range of the bone conduction sound-emitting component is increased, and the problem of poor sound quality caused by the lack of bass and treble bands of traditional bone conduction sound is improved. The miniaturization of the bone conduction clamping device is achieved, and the sound quality loss of the equipment is reduced, thereby improving the sound quality.

[0106] Figure 6 A schematic flow chart of a bone conduction-based clamping method provided by an embodiment of the present invention is shown in FIG. Figure 6 As shown, the method includes:

[0107] S601: The controller determines whether the food held by the clamping structure is ready for consumption.

[0108] S602: When the controller determines the food entrance clamped by the clamping structure, it drives the sound-generating component to generate a vibration signal. When the food contacts the inside of the oral cavity and / or the teeth, the vibration signal is transmitted to the human auditory system through the food and / or the clamping structure.

[0109] In this embodiment, the method can be applied to the above Figure 1 In the bone conduction-based clamping device shown, its implementation principle and technical effect are similar and will not be described here.

[0110] Optionally, in order to enable the user to intelligently match different sounds when selecting different foods to hold, it can help users with functional vision impairments to identify foods.

[0111] Figure 7 FIG. 1 is a flow chart of a bone conduction-based clamping method provided by another embodiment of the present invention. Figure 7 As shown, the method includes:

[0112] S701: The controller determines the type of food, and determines a sound source that matches the type of food.

[0113] The controller can match the corresponding sound source, such as a specific ringtone, according to the food type given by the food selection button set on the handle. It can also judge the material of the food according to the gripping force given by the sensor. For example, there is a corresponding relationship between the hardness or weight of the food and the gripping force, and different sound sources can be matched according to different materials.

[0114] S702: The controller determines whether the food held by the holding structure is ready for consumption.

[0115] S703: When determining the food entrance clamped by the clamping structure, the controller drives the sound-generating component to generate a corresponding vibration signal according to the matched sound source.

[0116] S704: When food contacts the inside of the oral cavity and / or the teeth, the clamping device transmits the vibration signal to the human auditory system through the food and / or the clamping structure.

[0117] In this embodiment, the method can be applied to the above Figure 1 In the bone conduction-based clamping device shown, its implementation principle and technical effect are similar and will not be described here.

[0118] For the methods of the above embodiments, in order to intelligently match the identity type of the user, in a possible implementation manner, the controller can also determine the type of user corresponding to the oral cavity according to the size of the teeth in the oral cavity obtained at the entrance, and determine the sound source matching the user type and the size of the playback volume;

[0119] The driving of the sound-generating component to generate a vibration signal includes: driving the sound-generating component to generate a corresponding vibration signal according to the matched sound source and the size of the playback volume.

[0120] In another possible design, in order to automatically determine whether the clamped food has been eaten or when there is no food, it is intelligently determined whether the user still needs the clamping device to work, so as to improve the user experience. The above embodiment may also include that when the controller determines that the clamping structure does not clamp food and the clamping structure is fully or partially inlet, it stops driving the sound-generating member and determines the duration of the full or partial inlet of the clamping structure;

[0121] When the controller determines that the duration of the entrance is greater than a preset duration threshold, the controller re-drives the sound-generating component to generate a vibration signal.
