I need to deliver about 40 watts to a piezo tweeter at 30 khz. The tweeter is an CTS ksn1016A and is rated at 45 watts and is good for 40 khz. The amp is an LM7828 rated at 40 watts into 8 ohms. The problem is the tweeter has an capacitive reactance of 84 ohms at 30khz. The impedance mismatch is.

MD1712 is a two-channel, five-level, high voltage and high speed transmitter driver IC. It is designed for medical ultrasound imaging applications, but can also be used for metal flaw detection, Non-Destructive Testing (NDT), and for driving piezoelectric transducers. We evaluate the speaker-to-speaker ultrasonic covert channel. In particular, we evaluate the acoustic response of passive speakers, headphones, and earphones to the near-ultrasonic range, when transformed into microphones (recall that such speakers are not designed to function as input devices).

What is the difference between the New Acouspade and the Acousopade Classic?

The main difference is that the new Acouspade has a Bluetooth connection and motion detection option. Both speakers can be connected to an audio device through 2 RCA connectors. Both speakers have the same power output (SPL). The directionality is also very similar. Due to different shapes the sound field distributions are slightly different. The new Acouspade is more suitable for short distance listening (1-3m). The Classic Acouspade, more for long distance listening (3-5m). The Classic is slightly more focused due to its circular shape.

Sound quality and low frequency response of the Acouspade speakers?

In case you are looking for HI-Fi directional sound, ultrasound-based directional speakers, like the Acouspade are not a good choice. These kind of speakers can create an extremely narrow beam of sound, however the sound quality – although very solid – can not be compared to the sound quality of regular speakers or headphones. Especially the low frequency reproduction is a weak spot.

What is the reach the Acouspade speakers?

The sound reaches up to 50m and is still well audible, however, for optimal performance regarding directionality, we recommend a distance between 1 and 5 meters from the listeners head.

How big is the listening area?

Ultrasonic Speaker Driver Wireless

The radiation angle of the Acouspade speakers is about 10 degrees. With this information you can calculate the sound covered area in different distances. At a typical mounting distance of 2-3m the audio footprint is about 1m2 (one square meter).
