1. Loaʻa i ka mea hoʻolele leo magnetic kahi electromagnet me kahi ʻiwi hao neʻe ma waena o nā pou ʻelua o ka magnet mau loa. Ke ʻole ke au i loko o ka wili o ka electromagnet, huki ʻia ke ʻiwi hao neʻe e ka huki pae pae o nā pou magnetic ʻelua o ka magnet mau loa a noho paʻa i ke kikowaena; Ke kahe ke au ma o ka wili, ua magnet ʻia ke ʻiwi hao neʻe a lilo i magnet bar. Me ka hoʻololi ʻana o ke kuhikuhi o ke au, loli pū ka polarity o ka magnet bar, i mea e wili ai ke ʻiwi hao neʻe a puni ka fulcrum, a hoʻouna ʻia ka haʻalulu o ke ʻiwi hao neʻe mai ka cantilever i ka diaphragm (cone pepa) e hoʻokuke i ka ea e haʻalulu wela.

2. Mea hoʻolele leo uila He mea hoʻolele leo ia e hoʻohana ana i ka ikaika uila i hoʻohui ʻia i ka papa capacitor. Ma ke ʻano o kona ʻano, ua kapa ʻia hoʻi he mea hoʻolele leo capacitor no ka mea ua kūʻē nā electrodes maikaʻi a me nā electrodes maikaʻi ʻole kekahi i kekahi. Hoʻohana ʻia ʻelua mau mea mānoanoa a paʻakikī e like me nā papa paʻa, hiki ke hoʻouna i ke kani ma o nā papa, a ua hana ʻia ka papa waena me nā mea lahilahi a māmā e like me nā diaphragms (e like me nā diaphragms alumini). E hoʻopaʻa a hoʻopaʻa a puni ka diaphragm a mālama i kahi mamao nui mai ke pou paʻa. ʻOiai ma kahi diaphragm nui, ʻaʻole ia e kuʻi me ke pou paʻa.
3. Nā mea ʻōlelo Piezoelectric ʻO kahi mea ʻōlelo e hoʻohana ana i ka hopena piezoelectric inverse o nā mea piezoelectric ua kapa ʻia he mea ʻōlelo piezoelectric. ʻO ka hanana i hoʻopili ʻia ai ka dielectric (e like me ka quartz, potassium sodium tartrate a me nā kristal ʻē aʻe) ma lalo o ka hana o ke kaomi, e hana ana i kahi ʻokoʻa hiki ma waena o nā wēlau ʻelua o ka ʻili, i kapa ʻia ʻo "ka hopena piezoelectric". ʻO kona hopena inverse, ʻo ia hoʻi, ka deformation elastic o ka dielectric i kau ʻia ma ke kahua uila, ua kapa ʻia ʻo "ka hopena piezoelectric inverse" a i ʻole "electrostriction".
