  • Patent number: 6636612
    Abstract: The invention provides a speaker having a number of features that cooperate to provide a small speaker 10 having a high sound pressure level output capability (volume), a wide frequency range, in particular from below 200 Hz to 20,000 Hz, low distortion, and that is magnetically shielded. The speaker 10 is suitable for mounting in, for example, a television where spaces are confined and stray magnetic fields are undesirable, yet high output is desirable and a wide frequency range is desirable to avoid the need for separate middle frequency (midrange) and high frequency (tweeter) speakers.
