Headphone Calculator

Rob Robinette

Mayelana nalolu hlelo lokusebenza

Le wokubala unemisebenzi emibili primary: page The 'Yokulalela Umsindo Resistor Network Calculator kuyokusiza ukucacisa elikhulu resistor amagugu for a ngehedfoni ukuba isikhulumi interface okuzokwenza elekthroniki ukufanisa headphones akho ukuba msindo isikhulumi usebenzisa inethiwekhi resistor. The ngehedfoni page 'Power Calculator' ngeke ukubala amandla ngehedfoni, zamanje kanye voltages. Inethiwekhi resistor esetshenziswa lolu hlelo a simple ezimbili resistor L-pad attenuator futhi ngokuvamile Kunconywa ngehedfoni-to-isikhulumi-amp resistor network interface.

Indlela Yokulalela Resistor Network Calculator Imiyalelo

1. Faka impedance yakho Isilinganiso Yokulalela Umsindo sika, Amplifier yakho Speaker Umthwalo Isilinganiso (ngokuvamile 4 noma 8 Ohms) kanye Amp sika lokukhipha impedance.

2. Chofoza inkinobho 'Calculate'. Noma nini a value lishintshwa inkinobho 'Calculate' kumele sichofozwa futhi.

Layisha Effective Somlomo umthwalo amplifier yakho 'ebona.' Umgomo ukufanisa lokhu amplifier yakho isikhulumi umthwalo Isilinganiso (ngokuvamile 8 Ohms).

Attenuation kuyinto ukuncipha decibel angu inethiwekhi resistor inikeza.

EFF Ucingo impedance iyona Ngempumelelo Indlela Yokulalela Umsindo impedance.

3. Ngokuba engeziwe Izibalo Network faka ngehedfoni yakho sensitivity in dB / MW and amplifier lalilinganiselwa voltage bese uqhafaza 'Calculate'.

Amplifier Power yiyona okuphumayo amp in Watts zibe Umthwalo Ngempumelelo Somlomo.

Amplifier yamanje inani amp in Amps zibe Umthwalo Ngempumelelo Somlomo.

Amplifier somsindo izinga dB lapho eliqhutshwa engena Umthwalo Ngempumelelo Somlomo.

Indlela Yokulalela Power yiyona milliwatts ababhekene headphones.

Indlela Yokulalela yamanje yiyona milliamps ababhekene headphones.

Indlela Yokulalela Loud iyona somsindo of the headphones in dB SPL (emnike Pressure Sound Level).

R2 dissipation amandla in milliwatts esetshenziswa up by resistor R2.

R3 dissipation amandla in milliwatts esetshenziswa up by resistor R3.

R2 Voltage Drop kuyinto drop in voltage yonkana resistor R2.

R3 + HP Voltage Drop kuyinto drop in voltage yonkana resistor R3 kanye headphones.

Indlela Yokulalela Power Calculator Iziqondiso

1. Faka amagugu in yellow kuhlanganise Indlela Yokulalela Umsindo yakho impedance Isilinganiso kanye Isilinganiso Ukuzwela in dB / MW (emnike milliwatt per). Uma umakhi wakho ngehedfoni libala Isilinganiselwa sensitivity in dB / V (emnike volt angu per) ukhetha dB / V ibhokisi lokuhlola. Ukuze abale amandla adingekayo ukuze kuzuzwe value somsindo faka somsindo wayefisa dB. Ukubala elikhulu kangakanani-amplifier ngeke ukushayela headphones akho ukungena amplifier sika Vrms isilinganiso.

2. Chofoza inkinobho 'Calculate'. Noma nini a value lishintshwa inkinobho 'Calculate' kumele sichofozwa futhi.

Indlela Yokulalela Ukuzwela ilingana lokho wangena ebhokisini yellow - uma ufaka sensitivity in dB / MW (lokumaka kungalawulwa) kuyothiwa aguqulwa ukuzwela in dB / V. Uma ufaka dB / V futhi uhlole ibhokisi ke kuyoba aguqulwe ukuze dB / MW.

Power @ 1Vrms amandla in milliwatts egijima ngokusebenzisa headphones uma 1 volt angu (root-kusho-square okulinganiselwa) signal audio uzibiza.

Current @ 1Vrms kuyinto zamanje milliamps egijima ngokusebenzisa headphones lapho signal a 1 volt angu audio sisetshenziswa.

Yini Edingekayo Wokufinyelela a somsindo Level

Faka Target yakho somsindo Level in dBSPL (emnike Sound Pressure Level) bese uchofoza inkinobho yimuphi 'Calculate'.

Power ezidingekayo yiyona amplifier amandla okukhipha in milliwatts adingekayo ukuze uthole headphones yakho Target somsindo Level.

Voltage ezidingekayo yiyona amplifier okukhipha voltage in volts adingekayo ukuze uthole headphones yakho Target somsindo Level.

Okudingekayo lokhona amplifier okukhipha yamanje milliamps adingekayo ukuze uthole headphones yakho Target somsindo Level.

Yeka Loud Ingabe i Amplifier Drive Headphones Your

Faka amplifier yakho Vrms okuphumayo rating in volts bese uchofoza inkinobho yimuphi 'Calculate'.

Indlela Yokulalela somsindo sikhulu kangakanani headphones akho izodlala dBSPL (emnike Pressure Sound Level).

Amplifier Power yiyona amplifier amandla okukhipha in milliwatts.

Amplifier yamanje inani amplifier yamanje milliamps.
