Abstract: A method, a system, and a device for transmitting data through an earphone and a computer storage medium are provided. A first data type of to-be-transmitted data is acquired, a second data type set for an FIR filter coefficient is acquired, and a sum of the number of decimal places indicated by the first data type and the number of decimal places indicated by the second data type is determined. A data type which indicates a number of decimal places that is at least two orders more than the sum is determined among preset data types as a third data type of an FIR filtering result, and FIR filtering is performed on the to-be-transmitted data to obtain a target filtering result and transmit the target filtering result.
