The power receiving element in FIG. 7a is a voice coil 31, and the vibrating element is a magnet 41, but the specific forms of the power receiving element and the vibrating element are not limited to this.

It should be noted that the magnet 41 in this embodiment may also be a magnet composed of a coil, or a magnet composed of a coil and a magnet. Similarly, the voice coil 31 may also be a magnet composed of coils and/or magnets. In this application, a magnet refers to a component that can generate a magnetic field or a structural module that can generate a magnetic field.

The present invention does not limit the specific form of the magnet, and all components capable of generating a magnetic field fall within the scope of the magnet described in the present invention.

The voice coil 31 and the magnet 41 form a set of transducer units 51, and the transducer units 51 generate vibration signals according to the electrical signals sent by the wires 21. When the power receiving element and the vibrating element are both determined elements, the frequency response characteristic of the transducer unit 51 is determined accordingly, and the sounding module has a fixed frequency response curve. In this embodiment, the function of the transducer unit 51 is to convert electrical energy through the voice coil 31 into a magnetic field.

Figures 7b to 7e are respectively structural schematic diagrams of the second to fifth types of transducer units in this embodiment. As shown in Figs. 7b to 7e, in another alternative embodiment, the bone conduction sound emitting structure 5 includes at least two power receiving elements and/or at least two vibrating elements, whereby the power receiving element and the vibrating element At least two sets of transducer units are formed, and each transducer unit is used to generate a corresponding vibration signal in response to an electrical signal sent by an external device 8 (not shown in the figure). When the transducer unit includes at least two power receiving elements and the power receiving element is a voice coil, the multiple voice coils may be arranged coaxially, side by side, or arranged in other ways. In each transducer unit, if there are vibration groups formed by multiple sets of magnets and coils, each vibration group can have different frequency response characteristics. Further optionally, each group of transducer units may have the same frequency response characteristic, or may have 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, so that a group or group with specific frequency response characteristics can be selected according to specific conditions. The vibration of multiple sets of transducer units can significantly improve the sound quality.

As shown in Figure 7b, in an alternative embodiment, the number of power receiving elements and vibrating elements are the same, and the power receiving elements correspond to the vibrating elements one-to-one. Each power receiving element is connected to an external device through a wire 21 and a connector 2 8 Electrically connect and drive a corresponding vibration element to vibrate, thereby forming multiple groups of transducer units. The lollipop based on bone conduction sound shown in Figure 7b includes two power receiving elements and two vibrating elements to form two sets of transducer units, namely transducer unit 521 and transducer unit 522. The frequencies of the multiple sets of transducer units The response characteristics can be different. The external device 8 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 frequency of the resonance peak of the external device 8 and the frequency band characteristics of the sound information One and several groups of transducer units with the highest matching degree send corresponding electrical signals. In FIG. 7b, the power receiving elements are voice coil 321 and voice coil 322, and the vibrating elements are magnet 421 and magnet 422, but the specific forms of power receiving elements and vibrating elements are not limited to this.

In another alternative embodiment, as shown in FIG. 7c, the bone conduction sound emitting structure includes at least two vibrating elements and forms at least two sets of transducer units, and the at least two sets 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. In Figure 7c, the power receiving element is a voice coil, and the vibrating element is a magnet. Of course, the power receiving element and the vibrating element may also be other elements. As shown in FIG. 7c, the sound generating component includes a voice coil 331 and two magnets 431 and 432. The two magnets 431 and 432 are respectively arranged on both sides of the voice coil 331, and the two magnets 431 and 432 are both located in the voice coil 331. Within the effective range of the magnetic field, that is, the voice coil 331 can drive both the magnet 431 and the magnet 432, thereby forming two sets 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 voice coil 331. The two magnets 431 and 432 have different parameters such as weight, size, material, and magnetic air gap between the two magnets 431 and 432 and the voice coil 331. Therefore, the two sets of transducer units 531 and 532 have different frequency response characteristics. When the external device 8 sends an electrical signal to the voice coil 331 through the connector 2 and the wire 21, the two magnets 431 and 432 are driven to vibrate, so the vibration signals output by the lollipop based on bone conduction sound are two sets of transducer units The superimposed effects of 531 and 532 can improve the sound quality of lollipops based on bone conduction sound and reduce the overall volume of sound-producing parts. The two sets of transducer units 531, 532 in FIG. 7c can be formed as a pair of transducer units, and those skilled in the art can set one or more transducer units as shown in Fig. 7c in the bone conduction sound generating structure according to actual needs. right.

In another alternative embodiment, as shown in Figures 7d and 7e, the bone conduction sound emitting structure includes at least two power receiving elements and forms at least two sets of transducer units, and the at least two sets of transducer units have a common One vibrating element, that is, at least one vibrating element can be driven by at least two power receiving elements to vibrate, thereby reducing the overall volume of the sound generating module. In Figure 7d, the power receiving element is a voice coil, and the vibrating element is a magnet. In Fig. 7e, the power receiving element is a piezoelectric piece, and the vibrating element is a vibrating plate. It can be understood that the power receiving element and the vibrating element may also be other elements.

Further optionally, as shown in FIG. 4d, the sound generating component includes two voice coils 341, 342 and a magnet 44, and the magnet 44 is within the effective range of the magnetic fields generated by the two voice coils 341, 342, that is, the magnet 44 can The voice coil 341 can also be driven by the voice coil 342, thereby forming two sets of transducer units, namely the transducer unit 541 and the transducer unit 542. It is understandable that those skilled in the art can set more power receiving elements to share one vibrating element to form multiple groups of transducer units. The two voice coils 341 and 342 may be arranged on the same side of the magnet 44 or may be arranged on both ends of the magnet 44 respectively. Optionally, the magnet 44 and the two voice coils 341 and 342 are coaxially arranged to facilitate balanced driving of the magnet 44. The number of turns of the two voice coils 341, 342, the material, and the magnetic air gap with the magnet 44 may be different. Therefore, the two sets of transducer units 541, 542 have different frequency response characteristics. The external device 8 can send an electrical signal to one of the voice coils to drive the magnet to vibrate according to the frequency band characteristics of the sound information. Specifically, the external device 8 sends corresponding electrical signals to a group of transducer units that have the highest matching degree between the frequency of the resonance peak and the frequency band characteristics of the sound information through the connector 2 and the wire 21. The external device 8 can also send electrical signals to the two voice coils 341, 342 through the connector 2 and the wire 21, so that the magnet 44 is driven by the superimposed alternating magnetic field generated by the two voice coils 341, 342, which can increase the amplitude of the magnet 44 Thereby increasing the volume. The two sets of transducer units 541, 542 in Fig. 4d can be formed as a pair of transducer units. Those skilled in the art can set one or more transducer units as shown in Fig. 7d in the bone conduction sound generating structure according to actual needs. right.

Further optionally, as shown in FIG. 7e, the bone conduction sound generating structure includes two vibrating plates 451, 452 and six piezoelectric plates 351, 352, 353, 354, 355, 356, of which three piezoelectric plates 351-353 It is mechanically connected to different positions on the vibrating plate 451, and the other three piezoelectric plates 354-356 are mechanically connected to different positions on the other vibrating plate 452, that is, the three piezoelectric plates share one vibrating plate. Thus, the sounding module forms six groups of transducer units, namely transducer units 551-556. The vibrating plate is connected to the housing 1, and the piezoelectric sheet is excited by the electrical signal to produce mechanical deformation to drive the vibrating plate to generate a vibration signal, and the vibrating plate conducts the vibration signal to the head 11 of the housing 1. By changing the model of the piezoelectric sheet, the connection position of the piezoelectric sheet and the vibrating plate, and the size and material of the vibrating plate, the frequency response characteristics of each group of transducer units can be adjusted. The six groups of transducer units 551-556 in Figure 7e The frequency response characteristics of can be completely different, which can further broaden the frequency response range of the sound module.

It can be understood that the number of the aforementioned piezoelectric sheets is not limited to three, that is, the number of piezoelectric sheets can be at least one, and the position of the piezoelectric sheets is not limited in this application. Those skilled in the art can set the pressure according to the specific situation. The number of electric plates and the position of each piezoelectric plate on the vibrating plate.

In addition, the entertainment device based on bone conduction sound in any one of the above embodiments may further include a switch element, and the user can input a switch signal or a volume adjustment signal through the switch element, and transmit this signal to the external device and the bone conduction sound structure, The implementation of the switch element can be a button switch, or a toggle switch, or a volume regulator, or a sensor, for example, including a light sensor, a temperature sensor, a humidity sensor, a voice control sensor, a capacitance sensor, or at least two of them combination. Specifically, when the user puts the accessible part of the head 11 into the mouth, the photosensitive sensor detects that there is no light around it, which can be considered as triggering the instruction to open. Of course, in order to prevent misjudgment when holding the device in the hand, Temperature and humidity sensors can also be added, because the oral cavity temperature is higher than the body surface temperature, and the oral cavity is moist, the combination of the three can accurately determine the user's switching needs, thereby realizing automatic switching. The external device and the bone conduction sound generating structure send electrical signals to the corresponding one or more groups of transducer units in response to the turn-on signal sent by the switch.
