The terms "up", "down", "left", "right", "front", "back", "bottom" and the like indicate the orientation or position based on the orientation or position shown in the drawings, and are only for convenience of description, and cannot be understood as a limitation on the technical solutions.

[0032] It should be noted that the existing wall-mounted Bluetooth sound structure is connected directly with the wall socket through an external power adapter. Although this method can ensure continuous power supply, it has obvious defects: (1) the power cord is exposed on the wall, causing visual pollution and damaging the overall aesthetics of the indoor decoration; (2) the cable is exposed for a long time and is easily affected by environmental temperature and humidity, accelerating the aging of the insulation layer; (3) dust accumulation at the interface leads to poor contact.

[0033] Chinese Patent No. CN207251887U discloses a wall-mounted Bluetooth sound structure, which adopts a separate power supply structure. The first mobile power supply for supplying power to the Bluetooth sound box is built into the decorative body, and the power cord of the Bluetooth sound box extending outward is detachably connected with the first mobile power supply.

[0034] Although this scheme solves the problem of cable exposure to a certain extent, the decorative body and the sound box are only physically connected by the power plug. Under the action of gravity, the weight of the decorative body continuously acts on the plug-in part of the power cord, causing stress concentration of the metal contact and accelerating the fatigue failure of the contact. In a dynamic use scenario (such as slight collision during cleaning and maintenance), the plug-in part is worn out due to the shaking of the decorative body. The power cord is easily deformed in a stretched state for a long time, leading to increased impedance and power loss.

[0035] As shown in Figures 1-8 , the present embodiment provides a sound with a separate mobile power supply. The sound box body 10 and the decorative body 20 are physically and electrically connected through a double-channel connection architecture. Specifically, the mechanical connection channel is composed of a first locking unit 11 on the sound box body 10 and a second locking unit 21 on the decorative body 20. After the first locking unit 11 and the second locking unit 21 are locked, a rigid support is formed. The electrical connection channel is composed of a first electrical contact 12 on the sound box and a second electrical contact 22 on the decorative body 20. After the first electrical contact 12 and the second electrical contact 22 are in contact, low-impedance conduction is achieved. The mechanical connection channel and the electrical connection channel are separated in space, so that the force generated by the weight of the decorative body 20 is completely borne by the mechanical connection, avoiding the problem of mechanical load borne by the power cord in traditional plug-in connection. Moreover, the decorative body 20 can be independently detached, supporting multiple mobile power supplies 24 for rotation.

[0036] Specifically, the sound with a separate mobile power supply includes a sound box body 10 and a decorative body 20 with a built-in mobile power supply 24. The sound box body 10 and the decorative body 20 are detachably connected through a connecting piece. The connecting piece includes a first locking unit 11 and a first electrical contact 12 separately provided on the sound box body 10, and a second locking unit 21 adapted to the first locking unit 11 and a second electrical contact 22 adapted to the first electrical contact 12 provided on the decorative body 20.
