The invention discloses a mini horn for a portable device. The mini horn comprises a shell, a circuit board, a vibration membrane and a protective shell. The shell is annular. The upper end of the shell is stuck inside the body case of the portable device and the lower end of the shell is provided with an opening. The circuit board is arranged at the opening. The vibration membrane is arranged in the middle of the shell and is loaded on a flange of the middle of the shell. The protective shell is arranged between the periphery of the vibration membrane and the inner side of the body case of the portable device. The protective shell is ladder-like. The upper end of the protective shell is stuck inside the body case of the portable device and the lower end of the protective shell leans on the periphery of the vibration membrane. The outer periphery of the vibration membrane is also provided with a first flange extending upwards and attaching to the inner side of the shell. The lower end of the protective shell is provided with a second flange extending upwards and leaning on the first flange. The mini horn for the portable device has a simple structure, and allows the portable device to play the sound. Due to the waterproof structure, the mini horn has a waterproof function and prevents water from getting in.
Description
technical field [0001] The invention relates to a miniature speaker for a portable device. Background technique [0002] With the continuous improvement of people's living standards, the application of smart portable devices is becoming more and more extensive.
