The vibration system 1 includes a diaphragm 10 and a voice coil 11 for driving the diaphragm 10 to vibrate.
The sounder 100 further comprises two first pads 5 embedded in the frame 3 and two first pins 7 respectively assembled with the first pads 5, and the first pads 5 and the first pins 7 are used for electrically connecting the voice coil 11 with an external circuit.
The sounder 100 further includes two second pads 6 embedded in the frame 3 and spaced from the first pads 5, and second pins 8 assembled with the second pads 6. The two second pads 6 are electrically connected or disconnected, and the on/off state of the two second pads 6 can be detected by inputting a detected electric signal on the second pin 8, so that sounders from different suppliers can be distinguished. For example, the detected electrical signal is input through the second pin 8, and when the two second pads are electrically conducted with each other, the electrical signal displayed by the detecting instrument is 1; when the two second pads 6 are in the off state, the electrical signal displayed by the detection instrument is 0, and through the displayed different electrical signals, a user can distinguish the sounders from different suppliers during client assembly. In the present embodiment, the two second pads 6 are disposed at intervals, and are electrically connected to each other through a conductive member, such as an electric wire. The conductive member can also be embedded in the basin stand 3.
