Method and system for pairing true wireless stereo Bluetooth headset with Bluetooth playing equipment

The invention is applicable to the field of headsets, and provides a method and system for pairing a TWS Bluetooth headset with Bluetooth playing equipment. The method comprises the following steps that: when a cap of a headset charging box is opened, a cap opening detection switch detects that the cap of the headset charging box is opened, and sends a detection result to a controller of the headset charging box; the controller controls a first headset and a second headset to establish a temporary connection; the first headset and the second headset are controlled to find a headset with highest RSSI (Received Signal Strength Indicator) signal strength, and the first headset and the second headset establish the connection when the first headset and the second headset find the headset with the highest RSSI signal strength and receive a temporary connection request sent by the headset with the highest RSSI signal strength; and the first headset or the second headset as a main headset actively sends pairing request information to the Bluetooth playing equipment to request pairing. Through adoption of the method and system, the operation of pressing a product pairing key can be omitted,and mis-operation in the use process can be prevented. The method and system have better experience, and are very convenient.

Firing method for glazed ceramic teapot

The invention provides a firing method for a glazed ceramic teapot, an adopted supporting base and a manufacturing method of the adopted supporting base. The firing method for the glazed ceramic teapot includes the steps that after a teapot body is soaked in glaze water, the teapot body is reversely buckled on the supporting base, after the supporting base and the inner edge of a pot opening of the teapot body are bonded together through an adhesive, firing is carried out, and the supporting base is knocked after firing is completed, so that the supporting base falls off. The supporting base comprises a round base body, an annular supporting table is arranged close to the edge of the top of the base body, and a hole is formed in the base body. The teapot soaked in the glaze water is reversely buckled on the supporting base, then firing is carried out, the supporting base is knocked off after firing is completed, therefore, the phenomenon that the glaze water flows downwards when the teapot is fired to be accumulated into blocks on the bottom edge of the teapot can be avoided, the teapot with the bottom edge provided with a complete glaze surface can be obtained, the glaze surface of the teapot is complete, the overall ornamental value of the teapot is improved, the operation of grinding the bottom edge of the teapot is omitted, the manufacturing procedures of the teapot are reduced, and the cost is reduced.
