Analog dynamics – parameters of flows
All speaker systems analogue describes manufacturers use two basic quantitative parameters: power, expanding trade with countries in watts (W) and resistance is determined in ohms (?). These settings do not say, however, anything about the frequency response dynamics, but it makes a huge difference to sound quality. The General rule is that the larger the diameters of the speakers have an analog (or rather, their membrane), the better transmission of low frequencies (including low frequencies). Therefore, small speakers are analog, for example, 15 mm MG15 or 28-mm YD30 best suited for the task of the alarm in the mid / high frequencies (above a few hundred Hertz), but if you are looking for the dynamics of a small radio or MP3 player to the Arduino – select a slightly larger size YD78 or YD50.
Speaker system for playing analog audio signals
For simple applications, which reproduces the individual tones or a series of them, suit small analog speakers with a membrane made of a film. In such cases, the most important will be the selection of appropriate power dynamics, and therefore the size (diameter and overall thickness). Speakers such as 8-ohmic YD36 power of 0.5 W and a diameter of 36 mm surprisingly well in the creation of simple scratches of various intensity and frequency, although they are often used in small radio or toys where they are able to reproduce music or speech. Perfect also in combination with sound module (for example, player WAV/MP3) for Arduino, and in collaboration with minikomputerami like the Raspberry Pi. Remember to check the maximum power that can ensure the output of the module, if necessary, to pick up the appropriate amplifier.
Speakers that rozkręcą every party
For applications requiring more power, we recommend large speakers, an analog A-165 brand BLOW. In our store you will find two versions with a power of 200 W and ensure the max. output 4? and 8?. Model a-165 has a very wide throttle range, from low frequencies (45 Hz) to high frequencies (6 kHz) that allows you to use it to play music, even without an extra subwoofer. Very interesting solution are also miniature speaker system analog Adafruit Bone Conductor Source that transmit sound directly to the surface where you will be placed. Thus, the table, wardrobe or household items can become sources surprisingly sonorous and well sounding sound. With this small matrix password "jukebox" takes on an entirely literal meaning!
