ABSTRACT:
The invention relates to an improved piezoelectric loudspeaker for high frequency, more commonly known as a tweeter. The invention embraces a technological improvement which permits the size of the tweeter to be substantially reduced while maintaining or even improving its performance when compared to other tweeters. In the device, a diaphragm is placed at least partially inside a coil so that the size of the tweeter can be reduced. The coil activates a piezoelectric element which drives the diaphragm causing it to vibrate and produce sound.
