C\u00edvka mus\u00ed b\u00fdt pevn\u011b uchycena a spr\u00e1vn\u011b vycentrovan\u00e1 v magnetick\u00e9m poli. Membr\u00e1na by m\u011bla b\u00fdt pevn\u011b spojena s c\u00edvkou, aby se zajistilo efektivn\u00ed p\u0159enos vibrac\u00ed. Pro lep\u0161\u00ed zvukov\u00e9 vlastnosti je vhodn\u00e9 pou\u017e\u00edt tlumen\u00ed, kter\u00e9 minimalizuje ne\u017e\u00e1douc\u00ed rezonance.

Po dokon\u010den\u00ed konstrukce je nutn\u00e9 spr\u00e1vn\u011b zapojit m\u011bni\u010d do zesilova\u010de.

Po testov\u00e1n\u00ed je nutn\u00e9 kalibrovat a optimalizovat m\u011bni\u010d pro dosa\u017een\u00ed nejlep\u0161\u00edho zvuku. To zahrnuje nastaven\u00ed rezonan\u010dn\u00ed frekvence a optimalizaci citlivosti.
