This paper describes investigation of measuring methods of small size loudspeaker units for mobile equipment. Although conventional measurements utilize the standard enclosure or baffle specified in IEC 60268-5, these acoustical loads are not suitable for this perpose because they are too large to simulate housings of ordinary mobile equipment, for example mobile telephone sets. This paper presents two sorts of acoustical loads. One is a medium sized enclosure with satisfactory data repeatability. The other is a tube load with satisfactory small acoustical diffraction. |
