An assembly structure of flat speaker including at least two speaker units and one connecting structure is provided. Each speaker unit includes a first electrode, a vibrating film, and a second electrode. The connecting structure includes two conductive layers, and a first insulating layer. A first conductive layer is connected the first electrode through a contact area, and each has a first length and a third length parallel to the contact area. A second conductive layer is connected the second electrode through a contact area, and each has a second length and a fourth, a fifth length parallel to the contact area. The third length is less than or equal to a sum of the first lengths of the speaker units. A sum of the third, the fourth, and the fifth length is less than or equal to a sum of the first and second lengths.
