The invention discloses a portable electronic device capable of weighing, comprising an upper shell, a lower shell, a display, a mainboard and a weighing transducer, wherein the mainboard and the weighing transducer are arranged on the lower shell, the display is fixed on the upper shell, the upper shell as a weighing scale is arranged on the weighing transducer, and in the weighing state, the upper shell contacts the weighing transducer and applies gravity on the weighing transducer. An electronic device is integrated on the portable electronic device, and thus, the portable electronic devicehas the advantages of small size, convenience for weighing and no influence on original functions.
Description
technical field [0001] The invention relates to the technical field of electronic devices, in particular to a weighing portable electronic device. Background technique [0002] Weighing device is a common product in life production. At present, there are some portable electronic scales that can be carried with you. These electronic scales generally include keyboards, displays, main boards, weighing pans and load cells. The main boards include amplification and filtering circuits, analog / digital (A / D) converters and central processing units. After the object to be weighed is placed on the weighing pan, force is applied to the load cell, and the load cell converts the gravity into an analog signal of voltage or current, which is converted into a digital signal by the A / D converter after being processed by the amplification and filter circuit. The digital signal is calculated and processed by the central processor, and the peripheral functions and various interface circuits a...
