  • Patent number: 10735851
    Abstract: An Acoustic meta material (AMM) device for passive amplification of sound is described. The AMM amplifier device employs a deep sub-wavelength resonator design with high refraction index, which uses resonant amplification of the bass sound. An array of sub wavelength, single frequency channels are used, each resonating and amplifying at a different frequency in the bass frequency range. This is accomplished by having many different channels, each with an opening extending in a same, common, or substantially common direction. Thus, sound emanating from a speaker in a first direction continues in this direction until reaching and entering the openings of the plurality of channels. The sound from the speaker is in all transmitted frequencies of, for example, a musical recording or the like. However, only a specific frequency and/or harmonics thereof are substantially propagated through each channel.

The resonance body includes a resonance film and a resonance film frame. The sound guiding portion includes a first sound guiding member, a second sound guiding member and a back frame unit. The speaker structure forms a sealed sound chamber by combining the speaker body, the resonance body and the at least one sound guiding portion. When the speaker body generates a front sound wave and a guiding sound wave, the front sound wave is transmitted within the sound chamber to the resonance film to enhance low frequency sound effect, and the guiding sound wave is transmitted within the resonance cavity and forms a back sound wave, thus reducing noise in the sound region and enabling better extension of the sound wave towards low frequency range.

  • Patent number: 9100753
    Abstract: An acoustic transducer includes a sound-producing member at least partially disposed within the first magnetic flux gap region between the magnetic poles. The sound-producing assemblage is magnetically excited through a magnetic circuit that passes from a location outside the magnetic flux gap region to inside the magnetic flux region through an air gap. The moving member is controllably movable under the influence of at least one varying magnetic field, and its movement is constrained by a unique combination of mechanical restraints and magnetic restraints imposed upon the moving member by the interaction of a plurality of magnetic fields.

  • Patent number: 9008343
    Abstract: An annular diaphragm compression driver for electro-acoustic conversion has an annular diaphragm, which bears a moving coil, and a compression driver housing with a closed housing base. Opposite the housing base is a sound wave routing element having a sound discharge channel. The compression driver also has an annular magnet system unit, which has an annular magnet gap (M) and a compression chamber, adjoining the magnet gap (M), for the annular diaphragm. The open exit end of the sound discharge channel is in slot form and its entry start is annular. The sound path between the compression chamber and the entry start contains an annular collecting space. The collecting space and the sound discharge channel contain a central sound guidance body having a portion which merges to match the slot-like exit end. The sound discharge channel is formed between the sound guidance body and the sound wave routing element.

  • Patent number: 8917875
    Abstract: A circuit for operating loudspeakers includes a first, second, third and fourth loudspeaker circuit, having one input each for injecting a signal and one output each for connecting a loudspeaker input. The loudspeaker circuits are designed to amplify the injected signal and to provide the amplified signal at the outputs thereof. The loudspeaker circuits can, for example, be used for a 2.1 sound system. The three channels for a 2.1 sound system can be implemented by an amplifier circuit with four loudspeaker circuits, one loudspeaker circuit each being required for the two stereo channels left and right. A subwoofer channel can be driven differentially by two loudspeaker circuits. The stereo channels are, by contrast, only still connected to one loudspeaker circuit each, and so the stereo channels require at least one further common ground cable.

  • Patent number: 8848964
    Abstract: A fitting provided for earbud-type personal audio speakers may be formed as a homogeneous, integral component molded from an elastomeric polymer, such as silicone, urethane, or other elastomeric resins. A sleeve fitted to the speaker engages the fitting to the speaker, while ribs extending from the sleeve terminate in flutes conformal to an ear canal of a user. Axial insertion of the fitting and speaker into an ear of a user results in localized deflection of flutes and ribs in order to accommodate size and shape of an ear canal, resulting in transmission of sound from the speaker directly through the sleeve into an ear canal of a user, while also permitting environmental sounds to pass along a parallel path over the outside of the sleeve, between the ribs.
