Patent number: 11417928Abstract: A battery holding mechanism is adapted to selectively accommodate a first battery having a larger outer diameter, or two second batteries each having a smaller outer diameter. The battery holding mechanism includes a battery holder and a resilient positioning member. The battery holder defines therein an installation space configured to permit only the first battery or only the second batteries to be installed. When the first battery is installed, the first battery is positioned by the resilient positioning member. When the second batteries are installed, the second batteries are positioned by the resilient positioning member in a juxtaposed manner.Type: GrantFiled: June 8, 2020Date of Patent: August 16, 2022Assignee: MIPRO ELECTRONICS CO., LTD.Inventor: Sue Cheng

Patent number: 8428290Abstract: An input-panel-equipped portable speaker device includes a cabinet shell body configured to enclose an accommodation chamber in a longitudinal direction, and having left and right mounting walls opposite to each other in a transverse direction. The left mounting wall has an inner peripheral region defining a fitting opening. The right mounting wall has a positioning groove. An input panel is connected with an amplifier circuit board, and is disposed to cover the fitting opening. When a right board edge of the circuit board is brought to be fitted in the positioning groove, an outer peripheral region of the panel is brought to abut against the inner peripheral region so as to enable an air-tight engagement therebetween.Type: GrantFiled: June 16, 2011Date of Patent: April 23, 2013Assignee: Mipro Electronics Co., Ltd.Inventor: Sue Cheng
