Frequently Asked Questions
What is the difference between speaker and receiver?
Receivers are optimized for voice calls with frequency response focused on voice band (300Hz-8kHz) and higher impedance (32Ω) for lower power. Speakers provide full audio range (300Hz-20kHz) with 8Ω impedance for music playback. Contact BeiLuo FAE team for application guidance.
Use receiver for earpiece, speaker for loudspeaker.
What is the rated power of SPS1318RA?
The SPS1318RA has a rated power appropriate for its size and application. The speaker should be driven with an amplifier matched to this rating for optimal performance and reliability. Exceeding the rated power may cause damage or distortion. Contact BeiLuo FAE team for amplifier recommendations.
Match amplifier power to speaker rated power.
What is relates to SPS1318RA?
The SPS1318RA has standard impedance (typically 8Ω for speakers, 32Ω for receivers) compatible with most audio amplifiers. The impedance should be matched to your amplifier output for maximum power transfer. Contact BeiLuo FAE team for impedance matching guidance.
Match impedance to your amplifier output.
What is relates to SPS1318RA?
The SPS1318RA provides sound pressure level appropriate for its size and application. Higher SPL provides louder output for noisy environments. The SPL is measured at 10cm distance with standard test signals. Contact BeiLuo FAE team for SPL specifications.
Select SPL based on your loudness requirements.
What is the frequency response of SPS1318RA?
The SPS1318RA provides frequency response optimized for its application. Speakers typically cover 300Hz-20kHz for full-range audio, while receivers focus on 300Hz-8kHz for voice. The frequency response determines the audio quality and clarity. Contact BeiLuo FAE team for frequency response curves.
