1. • Acoustic coupler

2. Acoustic coupler

3. A transducer unit incorporating an acoustic coupler

4. In an exemplary embodiment, the electrically-isolating acoustic coupler (16) comprises film bulk acoustic resonators (FBARs).

5. It consists of a keyboard, an acoustic coupler and a printer or electronic screen or both.

6. The modem also has a data connector, telephone connections, acoustic-coupler connection and standarized miniature telephone jack

7. The modem also has a data connector, telephone connections, acoustic-coupler connection and standarized miniature telephone jack.

8. As an example, it was a Deaf man named Robert Weitbrecht who invented the acoustic coupler that enables us to access the telephone system.

9. And then he would download test versions to a borrowed Apple II over a phone line using an acoustic coupler, and then we would test.

10. The Hacker Bible is a compendium of documents and stories from the hacker scene, for example the instruction guide to the acoustic coupler named “Data-loo”(Germ.:Datenklo).

11. Conductors for acoustic signals in the form of an acoustic coupler, including such coupler with tubes for providing an acoustic connection between a signal-processing unit and acoustic output

12. Modems generally remained at 300 and 1200 bit/s into the mid-1980s, although over this period the acoustic coupler disappeared seemingly overnight as Smartmodem-compatible modems flooded into the market.

13. The modem is used for asynchronous data transmission between automatic data processing equipment via telephone lines in full duplex and acoustic-coupler mode at a speed of # or # bits per second

14. The modem is used for asynchronous data transmission between automatic data processing equipment via telephone lines in full duplex and acoustic-coupler mode at a speed of 300 or 1 200 bits per second.

15. The decision is often referred to as "any lawful device", allowing later innovations like answering machines, fax machines, and modems (which initially used the same type of manual acoustic coupler as the Carterfone) to proliferate.

16. With the Smartmodem, the computer could dial the phone directly by sending the modem a command. This eliminated the need for an associated phone to dial with, and in turn, the need for an acoustic coupler.
