Speakers parameters index
Today ,we still talk about whats speaker parameters will directly impact the sounds quality.
Yesterday, we have talk about Power, and what power is better for a Bluetooth speaker.Today we will talk about and frequency range and frequency response!
(1)frequency range: is refers to audio system replay minimum effective playback frequency and highest effective playback frequency range .
(2) Frequency response: is refer to the phenomenon that speaker happen sound pressure with frequency changes and occurre to increases or attenuation, and phase with frequency changes , when a constant voltage output audio signal connected with system .this sound pressure and phase relate to frequency changes (changes volume) called frequency response, units DB (Db) Frequency characteristics of sound systems indicate: ordinate of the decibel scale represent power and a logarithmic scale represent frequency response .
High frequency terminal point and low frequency terminal point is the frequency response of the device;When sound power lower than normal power 3dB, this power point called the high frequency terminal and low frequency terminal.The DB is more smaller ,frequency response curve is more flat and distortion is more smaller, the speaker will more higher performance. For example: a frequency response of a speaker for the 60Hz~18kHz +/3dB. This sometimes does not distinguish between the two concepts, called frequency response.enough frequency response of 20~20000Hz is enough. Less than 20Hz voice, cannot be heard but one of the other senses can feeling, can feel bass, and therefore to play a variety of instruments and language in order to perfect signal amplifier to achieve the target of high fidelity, harmonic tones to be replayed.
Tomorrow,i will talk about that Db and degree of distortion, they are counterproductive, so we must control well their's relationship, otherwise will poor the speaker timbre and HI-FI.
