Description

SOUND PRODUCING DEVICE AND CLEANING DEVICE REFERENCE TO RELATED APPLICATION [0001] The priority application of the present disclosure is Chinese Patent Application No. 202322306718.0, filed in China on August 25, 2023, which application is hereby incorporated by reference in its entirety. TECHNICAL FIELD [0002] The present disclosure relates to the field of smart home technology, particularly to a sound-producing device and a cleaning device. STATE OF THE ART [0003] With the continuous development of smart home technologies, cleaning robots are increasingly used in daily cleaning work, and the intelligence of cleaning robots is also constantly developing, which brings many conveniences to life. The control modes of the cleaning robot can be classified into manual button control, remote control, voice control and the like. Generally, the cleaning robot is further provided with a sound generating device for generating sound for information interaction. In particular, during voice control and remote control, the sound generating device operates in voice interaction and produces the control results as feedback — by generating sound. [0004] Generally, a sound generating device includes a speaker and a housing. The speaker is fitted in the housing, and together the speaker and the housing define a sound chamber in a sealed manner so that the sound generated by the sound generating device is more powerful, thereby improving the sound generating performance. On the other hand, to enable communication between the speaker and the main controller of the cleaning robot N 25 — In order to control the sound content of the speaker, a through hole is provided in the housing, and an electrical connection wire passes through the 3 hole in the housing, which in turn is connected to the main conductor outside the housing +. In order to enable the electrical connection wire to be fixed, the inner diameter of the through hole - is generally larger than the outer diameter of the electrical connection wire. The gap between the through hole and the electrical connection wire produces poor sealing of the speaker sound chamber, and 2 30 — sound leakage causes distortion of the speaker sound. 3 SUMMARY OF THE INVENTION [0005] To this end, the present disclosure provides a sound generating device and a cleaning device. [0006] One aspect of the present disclosure provides a sound generating device. The sound generating device comprises: [0007] a housing (100), wherein the housing (100) comprises a lead hole (110) and an interior space communicating with the lead hole (110); [0008] a sound generating means (200), wherein the sound generating means (200) is disposed in an interior space; [0009] an electrical connection line (300), wherein the electrical connection line (300) is electrically connected to the sound generating means (200), the electrical connection line (300) passes through the line hole (110), and the relative position between the electrical connection line (300) and the line hole (110) includes a sealing position; and [0010] a sound-blocking means (400), wherein when the electrical connection wire (300) is arranged in a sealing position relative to the electrical wire hole (110), the sound-blocking means (400) is arranged between the electrical connection wire (300) and the wire hole (110) to seal the gap between the electrical connection wire (300) and the wire hole (110). [0011] The sound-blocking means (400) is fixedly attached to the outer wall of the electrical connection line (300). When the electrical connection line (300) moves toward the sealing position relative to the wire hole (110), the sound-blocking means (400) is configured to extend into the wire hole (110) from the outside of the wire hole (110) and slide relative to the inner wall of the wire hole (110) so as to abut against the inner wall of the wire hole (110) to seal the gap between the electrical connection line (300) and the wire hole (110) when the electrical connection line (300) and the wire hole (110) are in the sealing position. The sound blocking means (400) comprises a contacting area and a guide area, and the guide area is located at an end of the contacting area that is remote from the sound generating means (200). The radial cross-sectional area of the guide region tends to decrease towards a direction further away from the contacting region. O 25 — [0014] As the electrical connection wire (300) moves toward a sealing position relative to the wire N hole (110), the sound-blocking means (400) is configured to extend into the wire hole (110) S through the guide area and slide relative to the inner wall of the wire hole (110) so that when the electrical connection wire (300) and the wire hole (110) are in the sealing position, the contacting area is in contact with the inner wall of the wire hole (110) to seal the gap between the electrical connection wire (300) and the wire hole (110). E [0015] The sound-blocking means (400) is fixedly attac
