[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0055] The applicant discovered that existing electric toothbrushes have a first space between the battery and the Type-C connector at the rear. This space accommodates the wires to prevent them from being pinched by the Type-C connector and the battery. Placing a single speaker in this first space fully utilizes this space. A second space is provided between the battery and the drive unit to prevent vibrations generated by the drive unit from being directly transmitted to the battery, thereby ensuring a stable electrical connection between the battery and the various electrical components.

[0056] In view of this, the present invention proposes an electric toothbrush 10 that can realize a dual-speaker arrangement without increasing the overall space volume of the toothbrush, thereby optimizing the space layout of the toothbrush. Figures 1 to 7 The electric toothbrush 10 according to an embodiment of the present invention is introduced. Specifically, the electric toothbrush 10 includes a housing 100 , a bracket 200 , a battery 300 , a driving unit 400 , a first speaker 500 , and a second speaker 600 .

[0057] Reference Figure 1 and Figure 7 First, let's introduce the housing 100. The housing 100 defines a receiving cavity 110, which is used to accommodate various functional components. Next, let's introduce the bracket 200. The bracket 200 is used to carry components such as the battery 300 and the drive unit 400. To facilitate the description and understanding of the assembly arrangement between the bracket 200 and the housing 100, a first direction X is defined. Figure 2With reference to the orientation in FIG, the first direction X points to the left-right direction. The bracket 200 can extend through the accommodating cavity 110 along the first direction X and be removably connected to the housing 100. It will be appreciated that the battery 300 can power the various functional components of the electric toothbrush 10. The battery 300 can be located within the accommodating cavity 110 and supported by the bracket 200.

[0058] Reference Figure 1 and Figure 2 The driving unit 400 is used to drive the brush head 900 to move to achieve oral cleaning. The driving unit 400 can be arranged in the accommodating cavity 110 and supported by the bracket 200. The driving unit 400 and the battery 300 are arranged opposite and spaced apart along the first direction X, which can prevent the vibration of the driving unit 400 from being directly transmitted to the battery 300, thereby ensuring the stability of the electrical connection between the battery 300 and other components. Figure 2 With reference to the orientation in FIG, the driving unit 400 can be disposed on the left side of the accommodating cavity 110 , and the battery 300 can be disposed on the right side of the accommodating cavity 110 .

[0059] Reference Figure 2 and Figure 3 The specific arrangement of the first speaker 500 is described below. The first speaker 500 can be located on the side of the battery 300 that is away from the driving unit 400 along the first direction X. It can be understood that the end of the electric toothbrush 10 that is away from the brush head 900 along the first direction X can be provided with a Type-C structure, and the first speaker 500 can be located in the space between the battery 300 and the Type-C structure.

[0060] Reference Figure 2 and Figure 3 The following describes the specific arrangement of the second speaker 600. The second speaker 600 can be located on the side of the battery 300 near the driving unit 400 along the first direction X, and is located between the battery 300 and the driving unit 400. In other words, the second speaker 600 can fully utilize the space between the battery 300 and the driving unit 400, optimizing the spatial layout within the toothbrush.

[0061] In the technical solution of the present utility model, the electric toothbrush 10 includes a housing 100, a bracket 200, a battery 300, a driving unit 400, a first speaker 500, and a second speaker 600. The housing 100 defines a accommodating chamber 110. The bracket 200 extends through the accommodating chamber 110 along a first direction X and is detachably connected to the housing 100. The battery 300 is disposed in the accommodating chamber 110 and supported by the bracket 200. The driving unit 400 is disposed in the accommodating chamber 110 and supported by the bracket 200. The driving unit 400 and the battery 300 are arranged opposite each other and spaced apart along the first direction X. In existing electric toothbrushes, the two speakers are arranged adjacent to each other, which increases the overall volume of the toothbrush and the processing cost. In this solution, the first speaker 500 is disposed on the side of the battery 300 along the first direction X that is away from the driving unit 400, and the second speaker 600 is disposed on the side of the battery 300 along the first direction X that is closer to the driving unit 400, and the second speaker 600 is located between the battery 300 and the driving unit 400. This solution fully utilizes the space between the drive unit 400 and the battery 300, achieving a dual-speaker arrangement without increasing the overall volume of the toothbrush, ensuring stereo sound and reducing manufacturing costs. Furthermore, because the first speaker 500 and the second speaker 600 are located on either side of the battery 300 along the first direction X, the distance between the first speaker 500 and the second speaker 600 and the human ear is greater than in a solution with two speakers arranged adjacent to each other. This further enhances the stereo sound effect and improves the user experience.

[0062] Reference Figures 3 to 5 , the specific layout position of the first speaker 500 is introduced below. In some embodiments, the electric toothbrush 10 includes a first barrel 700, and the first barrel 700 has a first cavity 710 and a first opening 720 that are mutually conductive. Along the direction perpendicular to the first direction X, the shell 100 can cover the first opening 720 to form a partially enclosed first sound cavity 120, and the first speaker 500 can be arranged in the first sound cavity 120 to achieve sound. Compared with the solution of adding other components to cover the first opening, this solution uses the shell 100 to cover the first opening 720, which can further optimize the internal structure of the toothbrush, increase the volume of the first sound cavity 120, and improve the sound effect.

[0063] Reference Figures 3 to 5, the specific layout position of the second speaker 600 is introduced below. In some embodiments, the electric toothbrush 10 includes a second barrel 800, and the structure of the second barrel 800 can be the same as that of the first barrel 700. The second barrel 800 has a second cavity 810 and a second opening that are mutually conductive. Along the direction perpendicular to the first direction X, the shell 100 can cover the second opening to form a partially enclosed second sound cavity 130, and the second speaker 600 can be arranged in the second sound cavity 130 to achieve sound. Compared with the solution of adding other components to cover the second opening, this solution uses the shell 100 to cover the second opening, which can further optimize the internal structure of the toothbrush, increase the volume of the second sound cavity 130, and improve the sound effect.

[0064] Reference Figures 3 to 6 In some embodiments, the bracket 200 includes a first base 210, which can connect the first cylinder 700 and the housing 100. The specific structure of the first base 210 is described below. The first base 210 includes a first through hole 220 that is connected to the first opening 720. The housing 100 can cover the first through hole 220 to form the first sound cavity 120. In this solution, the first base 210 can support the first cylinder 700, which can improve the stability of the assembly connection of the first cylinder 700. Moreover, because the first through hole 220 of the first base 210 is connected to the first opening 720, the volume of the first sound cavity 120 can be increased, thereby improving the sound effect.

[0065] Reference Figures 3 to 6 In some embodiments, the bracket 200 includes a second base 230, which can connect the second cylinder 800 and the housing 100. The specific structure of the second base 230 is described below. The second base 230 includes a second through hole 240 that is connected to the second opening. The housing 100 can cover the second through hole 240 to form the second sound cavity 130. In this solution, the second base 230 can support the second cylinder 800, which can improve the stability of the assembly connection of the second cylinder 800. Moreover, because the second through hole 240 of the second base 230 is connected to the second opening, the volume of the second sound cavity 130 can be increased, thereby improving the sound effect.

[0066] Reference Figure 5 The following describes the specific connection arrangements between the first speaker 500, the first barrel 700, and the first base 210. In some embodiments, a first support portion 711 is provided within the first cavity 710 of the first barrel 700. The first support portion 711 is configured to support the first speaker 500. The first support portion 711 may include a plurality of support ribs, each of which may be arranged crosswise, and the first speaker 500 may be placed on the support ribs.

[0067] Reference Figure 3The first speaker 500 can at least partially penetrate the first cavity 710 and abut against the first support portion 711. The specific penetration depth of the first speaker 500 can be determined according to actual conditions. Figure 6 A first recessed platform 211 can be provided on the side of the first base 210 facing the first cylinder 700, and the side of the first speaker 500 facing away from the first support portion 711 can abut against the first recessed platform 211. In this solution, the first speaker 500 passes through the first cavity 710, meaning that the first cylinder 700 can suppress significant movement of the first speaker 500 in a direction perpendicular to its insertion direction. Furthermore, because the first recessed platform 211 can abut against the first speaker 500, this solution can effectively improve the stability of the assembly connection of the first speaker 500.

[0068] Reference Figure 5 The following describes the specific connection arrangements between the second speaker 600, the second barrel 800, and the second base 230. In some embodiments, a second support portion is provided within the second cavity 810 of the second barrel 800, and is used to support the second speaker 600. The second support portion may include a plurality of support ribs, each of which may be arranged crosswise, and the second speaker 600 may be placed on the support ribs.

[0069] Reference Figure 3 The second speaker 600 can at least partially penetrate the second cavity 810 and abut against the second support portion.

Figure 6 A second recessed platform 231 can be provided on the side of the second base 230 facing the second barrel 800, and the side of the second speaker 600 facing away from the second support portion can abut against the second recessed platform 231. In this solution, the second speaker 600 passes through the second cavity 810, meaning that the second barrel 800 can suppress significant movement of the second speaker 600 in a direction perpendicular to its insertion direction. Furthermore, because the second recessed platform 231 can abut against the second speaker 600, this solution can effectively improve the stability of the assembly connection of the second speaker 600.

[0070] Reference Figure 3 In some embodiments, the electric toothbrush 10 includes a first foam 510, one side of which can be connected to the first speaker 500 and the other side of which can be connected to the first barrel 700. In this embodiment, the first foam 510 is disposed between the first speaker 500 and the first barrel 700, which can effectively suppress resonance between the first speaker 500 and the housing 100 when sound is emitted.

[0071] Reference Figure 3The electric toothbrush 10 includes a second foam 610. The configuration of the second foam 610 can be similar to that of the first foam 510. Specifically, one side of the second foam 610 can be connected to the second speaker 600, and the other side can be connected to the second barrel 800. In this embodiment, the second foam 610 is disposed between the second speaker 600 and the second barrel 800, effectively suppressing resonance between the second speaker 600 and the housing 100 when sound is emitted.

[0072] Reference Figure 3 and Figure 4 In some embodiments, the housing 100 includes a first sound outlet 121 that is in communication with the first sound cavity 120. The first sound outlet 121 can be single or multiple. Some embodiments of the present application are described by taking multiple first sound outlets 121 as an example. It should be noted that a first waterproof membrane 122 can be provided between the first sound outlet 121 and the first sound cavity 120. Furthermore, the first waterproof membrane 122 can be a breathable membrane. The first waterproof membrane 122 of this solution can effectively prevent water from entering the first sound cavity 120, ensuring that the first speaker 500 can continuously and stably produce sound.

[0073] Reference Figure 3 and Figure 4 In some embodiments, the housing 100 includes a second sound hole 131 that is in communication with the second sound cavity 130.
