2 x CQRobot Miniature Loudspeaker
Perfect for users creating sound projects with Arduino boards and require a small, efficient speaker solution.
Ideal for makers involved in DIY electronics projects needing an easy-to-integrate audio output option.
Excellent for educators seeking to incorporate sound features in student projects involving basic electronics and programming.
Not suitable for applications requiring high sound output as it's limited to 3 watts and small scale.
The CQRobot Speaker 3 Watt 4 Ohm is a small speaker suitable for various electronic projects. It comes with two speakers in the box and has a JST-PH2.0 interface. The product is plug and play for some systems while it requires stripping the wires and twisting them together to function for others. A customer cut off the plugs of the speaker and attached them to terminal blocks with no problem. Others wanted to use an alligator clip directly on the line, and a customer was not impressed with the volume. The speaker does not connect to the GPIO on a Raspberry Pi, but it can connect to an audio amplifier or a replacement speaker. The built-in new small speakers of the "jst-ph 2.0-n" model has improved sound quality and volume. The speakers worked as expected, are loud, and come with no grills to protect fingers. It's also small enough to fit into a 1/14 scale Tamiya RC Truck.
