Are you sure the diaphrams are bad? Most of the time air horns stop working or sound wierd because the air compressor is failing or has stopped pumping. Most compressors that do not have separate tanks suffer from lack of oiling. You can try oiling the compressor or just replace it........they are usually less than $70.
