[0024] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a handle assembly 100, mainly used in electric toothbrush handles. The handle assembly 100 includes a handle barrel 110, a barrel cap 120, and a speaker 130.

[0025] The handle cylinder 110 has a receiving cavity 111 with an opening 112 at one end. The cylinder cover 120 passes through the opening 112 and is disposed in the receiving cavity 111. The cylinder cover 120 has a placement groove 121 at one end facing the receiving cavity 111. The bottom wall of the placement groove 121 has a plurality of through holes 1211 arranged in an array. The speaker 130 is disposed in the placement groove 121.

[0026] The handle assembly 100 provided in the embodiments of this application has a handle cylinder 110 with a receiving cavity 111 having an opening 112 at one end. A cylinder cover 120 is disposed within the receiving cavity 111 through the opening 112. By forming a placement groove 121 on the side of the cylinder cover 120 facing the receiving cavity 111 and placing a speaker 130 within the placement groove 121, the speaker 130 is stably mounted on the cylinder cover 120, effectively improving the installation stability of the speaker 130 and thus ensuring the stability of the speaker 130's music playback function. Simultaneously, by forming a plurality of through holes 1211 arranged in an array on the bottom wall of the placement groove 121, the sound generated by the speaker 130 is evenly diffused to the outside of the handle assembly 100 through the multiple through holes 1211, which helps to improve the clarity of the sound and thus enhance the user experience.

[0027] like Figure 1 As shown, in one embodiment of this application, the bottom wall of the placement groove 121 is provided with a clearance groove 1212, the clearance groove 1212 is located in the inner circumferential direction of the placement groove 121, and the clearance groove 1212 is connected to the placement groove 121 and the through hole 1211 respectively.

[0028] In this embodiment, by creating an inner circumferential clearance groove 1212 on the bottom wall of the placement groove 121, and having the clearance groove 1212 connected to both the placement groove 121 and the through hole 1211, the contact area between the bottom wall of the placement groove 121 and the speaker 130 is effectively reduced. This reduces the obstruction of the bottom wall of the placement groove 121 to the sound emitted by the speaker 130, allowing the sound generated by the speaker 130 to first converge in the clearance groove 1212, and then be evenly diffused to the outside through the clearance groove 1212 and multiple through holes 1211, thereby further improving the clarity of the sound and enhancing the user experience.

[0029] In the above embodiments of this application, the handle assembly 100 further includes a first adhesive layer, which is located on the outer periphery of the clearance groove 1212 and is bonded to the bottom wall of the speaker 130 and the placement groove 121, respectively.

[0030] In this embodiment, by providing a first adhesive layer on the outer periphery of the clearance groove 1212, which is respectively bonded to the bottom wall of the speaker 130 and the placement groove 121, the speaker 130 is stably placed in the placement groove 121 through the first adhesive layer, ensuring the installation stability of the speaker 130. On the other hand, the first adhesive layer being located on the outer periphery of the clearance groove 1212 also avoids obstructing the sound emitted by the speaker 130, thereby helping to ensure the clarity of the sound.

[0031] like Figure 1 and Figure 2As shown in the above embodiments of this application, the handle assembly 100 further includes a buffer damping layer 140, which is disposed on the side of the speaker 130 near the bottom wall of the placement groove 121 and located on the outer periphery of the clearance groove 1212. The first adhesive layer is bonded to the buffer damping layer 140 and the bottom wall of the placement groove 121 respectively.

[0032] In this embodiment, a buffer damping layer 140 is provided on the outer periphery of the clearance groove 1212 on the side of the speaker 130 near the bottom wall of the placement groove 121. This buffer damping layer 140 absorbs the impact of sound waves from the speaker 130 on the cover 120, preventing low-frequency signals generated by the vibration of the cover 120 from interfering with the normal sound output of the speaker 130, thereby improving the purity and clarity of the sound quality. Simultaneously, the location of the buffer damping layer 140 on the outer periphery of the clearance groove 1212 also prevents it from obstructing the sound emitted by the speaker 130, thus ensuring sound clarity.

[0033] In the above embodiments of this application, the handle assembly 100 further includes a second adhesive layer, which is located on the outer periphery of the clearance groove 1212 and is bonded to the speaker 130 and the buffer damping layer 140 respectively.

[0034] In this embodiment, the second adhesive layer is bonded to both the speaker 130 and the damping layer 140, while the first adhesive layer is bonded to both the damping layer 140 and the bottom wall of the placement groove 121, so that the speaker 130 and the damping layer 140 are stably disposed as a whole within the placement groove 121. Simultaneously, the fact that the second adhesive layer is located on the outer periphery of the clearance groove 1212 also prevents it from obstructing the sound emitted by the speaker 130, thus ensuring sound clarity.

[0035] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the handle assembly 100 further includes a dustproof layer 150, which is disposed in the clearance groove 1212 and covers the plurality of through holes 1211.

[0036] In this embodiment, a dustproof layer 150 covering multiple through holes 1211 is provided in the air-proof groove 1212 to prevent external dust from entering the air-proof groove 1212 and the placement groove 121 through the through holes 1211, thereby affecting the sound quality purity and clarity of the speaker 130.

[0037] In any of the above embodiments of this application, the side wall of the placement groove 121 is provided with a limiting buckle, which is used to restrict the speaker 130 from leaving the placement groove 121, so as to further improve the installation stability of the speaker 130.

[0038] like Figure 2 As shown, in any of the above embodiments of this application, the handle assembly 100 further includes a mounting bracket 160, which is disposed in the receiving cavity 111 and located at one end of the cylinder cover 120 facing the receiving cavity 111. A limiting protrusion is provided at one end of the mounting bracket 160 near the cylinder cover 120. The limiting protrusion is used to restrict the speaker 130 from disengaging from the placement slot 121, so as to further improve the installation stability of the speaker 130.

[0039] This application also provides an electric toothbrush handle, including the handle assembly 100 described in the above embodiments.

[0040] The electric toothbrush handle has the handle assembly 100 of any of the above embodiments, and therefore has all the beneficial effects of the handle assembly 100, which will not be described in detail here.

[0041] This application also provides an electric toothbrush, including the electric toothbrush handle described in the above embodiments.

[0042] The electric toothbrush has the electric toothbrush handle of the above embodiments, and therefore has all the beneficial effects of an electric toothbrush handle, which will not be described in detail here.

[0043] In summary, this application proposes a handle assembly 100, which includes a handle cylinder 110, a cylinder cover 120, and a speaker 130. The handle cylinder 110 has a receiving cavity 111 with an opening 112 at one end, and the cylinder cover 120 is disposed within the receiving cavity 111 through the opening 112. By creating a placement groove 121 on the side of the cylinder cover 120 facing the receiving cavity 111 and placing the speaker 130 within the placement groove 121, the speaker 130 is stably mounted on the cylinder cover 120, effectively improving the installation stability of the speaker 130 and thus ensuring the stability of the speaker 130's music playback function. Simultaneously, by creating multiple through holes 1211 arranged in an array on the bottom wall of the placement groove 121, the sound generated by the speaker 130 is evenly diffused to the outside of the handle assembly 100 through the multiple through holes 1211, which helps to improve sound clarity and thus enhance the user experience.
