Abstract: An electroacoustic transducer having an alternative finger structure is provided. The number of fingers of a cell of length A is divisible by four. The electrode fingers of the cell are divided into four groups. The distance (Δ2) between the second group and the third group is less than the distance (Δ1) between the first group and the second group and less than the distance (Δ3) between the third group and the fourth group.
