  • Patent number: 10009682
    Abstract: A new audio transducer for mobile devices having a collar with side openings that provide side venting to a back volume within an enclosure. The side openings eliminate the need for a typical frame and back vents thereon, which leads to a smaller size speaker. Each of the side openings have a maximum size less than the size of an adsorber material, which prevents the adsorber material coming into contact with the magnets, coil, and membrane of the speaker. The side openings and the size thereof also permit the enclosure to be directly filled with an adsorber material. The direct filling of the adsorber leads to more even and complete distribution of the adsorber within the back volume, which, in turn, improves sound quality of the speaker.

  • Publication number: 20170099536
    Abstract: A new audio transducer for mobile devices, in particular for a micro speaker, having a coil assembly having a coil, a pair of leads extending from the coil, and a flexible printed circuit having a pair of contact pads to which the leads are directly electrically connected. An advantage of this new speaker is the reduced number of electrical connections between the leads of the coil and the driver of the coil. This helps to reduce the number and size of the parts of the micro speaker and aids in increasing sound quality and durability of the speaker.

  • Patent number: 7796773
    Abstract: In a communication device (1) that is designed to deliver sound, in an against the-ear mode, into a space (22) bounded by the ear and, in an away-from-the-ear mode, into an acoustic free space, a loudspeaker (3) is provided for generating the sound and a holding device (2) is furthermore provided, which holding device (2) comprises a first holding-device region (16) via which, in the against-the-ear mode, the sound generated by the loudspeaker (3) can be delivered without hindrance by the ear and which holding device (2) comprises a second holding-device region (15A) that does not comprise the first holding-device region (16) and via which, in the against-the-ear mode, the sound generated by the loudspeaker (3) can be fed to the space (22) bounded by the ear and a first sound-conveying device is furthermore provided with whose aid the sound generated by the loudspeaker (3) can be conveyed, in the away-from-the-ear mode, through the first holding-device region (16) into the acoustic free space, and a second so

  • Patent number: 7644801
    Abstract: A membrane (2) for an electroacoustic transducer (1) is disclosed, wherein a thickness (d) of said membrane (2) and an average Young's modulus (Eavg) of said membrane (2) are chosen in such a way that the critical load (Fbc), which causes the membrane (2) to buckle and/or crinkle, is increased compared to a reference membrane. The reference membrane made of Polycarbonate has the same shape, dimension, and stiffness in its direction of movement (MOV) as said membrane (2). According to the result of investigations on buckling and/or crinkling, said effect occurs with different critical buckling/crinkling loads for membranes of the same shape and dimension, but made of different materials, even when the stiffness of the membranes in their direction of movement—and hence their resonant frequency—is identical.

  • Patent number: 6681024
    Abstract: A device (8) which includes an electroacoustic transducer (7) for the acoustic reproduction of sound signals to an ear (14) of a user (2) who assumes a user position at the device. The transducer is optimized for the acoustic reproduction of speech-signal sound waves and is equipped with arrangement means (25) for realizing a distinct directivity for the speech-signal sound waves emitted by the transducer. As a result of its directivity, the transducer directs the speech-signal sound waves which it emits preferentially to the ear of a user who is in the user posture.
