[0054] In some embodiments, a vent hole penetrating the inside and outside of the housing 1 is provided on the side of the housing 1 where the speaker 2 is mounted, and the paper tube of the speaker 2 at least covers the vent hole. The vent hole ensures the balance of sound pressure inside and outside the speaker 2 cavity, avoids sound backflow and attenuation, prevents the sound channel from being blocked, and enhances sound penetration. The vent hole improves the sound output quality of the speaker 2, prevents the sound from being muffled or unclear, and maintains the stability of the device's acoustic performance.

[0055] In some embodiments, a sealing ring is fitted at the connection between the connector 3 and the corresponding through hole and the connector 3. The sealing ring is fitted between the root of the connector 3 and the housing 1. After the connector 3 is inserted into the through hole, the sealing ring fits and fills the gap, preventing water and dust from entering. The connector 3 part achieves structural sealing and reinforcement, improves the environmental adaptability of the electrical interface area, and reduces short circuits and corrosion caused by water ingress into the connector 3.

[0056] In some embodiments, a sealing ring is fitted at the connection between the connector 4 and the corresponding through hole and the connector 4. As a combined communication and power supply interface, the connector 4 has higher sealing requirements. By designing the sealing ring, the long-term reliable operation of the connector 4 is ensured, the safety level of the connector 4 interface in high humidity and high dust environments is improved, and the overall protection level of the system is enhanced.
