ade tak sape2 yang expert pasal piezo transducer ni? aku tgk mcm menarik je piezo ni kalau wat electronic drum..aku dah try research tapi tak berapa paham..yang aku paham die tukar tenaga kinetik ke tenaga elektrik..
ade sape2 penah gune piezo ni utk wat electronic drum tak?

aku tgk mamat ni wat cam cool je tapi aku tak paham pasal circuit2 tu |

piezo yg aku tau sejenis material yg leh induced electric bile stress dikenakan.. kalau kau dalam bidang material science, kau leh wat dgn doping material lain ke other material ntuk polarizekan electric dipole moment.. ade gak piezo yg bile kenakan electric dia berubah bentuk..
kat drum pad etc, bile kau ketuk at certain point, vibration kat skin akan transfer ker tempat yg kau lekatkan piezo material tu.. dari situ piezo tu akan kena stress(yg guna kat drum mmg sensitive sebb aku guna electronic skin gak) so change in electric dipole moment, so mangnetic fluk pun berubah then current induced(faraday's law)..
since resistor involve dalam circuit tu, aku rasa la(aku bukan bidang electronic) tu ntuk filter.. sebb piezo ni sensitive thus create what we called in optic as quasimonochromatic(aku tak tau kalau dalam signal electronic dia panggil ape.. tapi same la).. nak buang noise tu kau perlukan low pass filter.. so aku suspect resistor tu provide that.. and bila ade filter, sinusoidal wave ni akan drift.. i mean ade delay kat situ.. and aku rasa should had capacitor on that circuit tpi takde.. diode ntuk bridge kot.. arghhhh aku pening!!
berbalik pada piezo, ntuk more generalize, bukan tenaga kinetik but potential energy yg involve..
tu je la yg aku tau.. tu pun ntah betul ke idak sebb aku bukan dak material.. tpi ade le kejap blaja material science(satu sem)

Buat dulu bro,tiru je.bab theory understanding itu kemudian hari boleh address.
macam saya la,rosak kan 5 amp baru dapat baiki 1 amp..haha..gurau je.

amacam boleh by julai buat dan post kat sini.??

Aku x bace abis lagi link yg dpostkan itu, tp aku penah tgk, orang pakai piezo sensor kat drum elektronik tu pakai siren elektronik i.e. piezo buzzer. (siren yg ade kat kad2 harijadi or hari raya yang bukak jer kuar bunyi-bunyian tu)..
mungkin ianya boleh dicuba, sebab sefaham aku, piezo sensor ni utk sensor tekanan yg dikenakan kpdnya..and die akan convert tekanan tu kepada tenaga elektrik. cuba gugel DIY Electronic drum, sure jumpe org pakai piezo buzer ni as a piezo sensor. macam speaker, kite boleh gak pakai speaker ni as microphone, so aku rase kite boleh apply bende yg same dlm piezo ni..
*mebi silap...tp boleh cube since piezo buzzer tu murah jer kan..hehe

try google...
dulu aku penah tengok, orang buat custom electronic drum pad..
ada yang penah tunjuk internal pad drumpad tu, which is memang pakai piezzo..

| setelah aku mengharu birukan otak..pasal piezo tu tade masalah,yg masalah circuit tu..yg mana nak bagi ade bunyi symbal snare sume tula..solution paling senang bli drum module..lepas tu sambungkan je kat piezo tu..masalahnye aku tade duit nak bli drum module haha..mane nak cari drum module yang murah2 ye..piezo aku dah siap2kan.. |

kalau ko terer, cuba ko carik midi controller keys (usb) yang murah2... lepas tu ko connectkan piezo pad untuk gantikan key. contohnya note C = snare...
lepas tu terus connect to PC via USB tanpa guna module...
pastu tu share ye..
rasaya nya aku penah tengok modification ni somewhere kat internet...
