  • Driver holder, driver module, and headset
    Patent number: 12413889
    Abstract: A driver holder is disposed inside a housing. This driver holder has a tubular portion formed in a tubular shape, and a driver is accommodated inside the tubular portion. Further, the tubular portion is press-fitted into a module case arranged inside the housing. Here, an opening at one end side in an axial direction of the tubular portion configures a first sound path that communicates the driver with the exterior of the housing. Further, a groove formed at a surface of the tubular portion configures a second sound path which is communicated with the first sound path and extends to a microphone arranged outside the tubular portion.

  • ACOUSTIC SIGNAL OUTPUT DEVICE
    Publication number: 20250168557
    Abstract: There is provided an acoustic signal output device that does not completely block the ear canal and is capable of suppressing sound leakage into the surroundings. There is provided an acoustic signal output device 10 including a structure portion provided with one or more sound holes 121a to emit an acoustic signal AC1 to outside and one or more sound holes 123a to emit an acoustic signal AC2 to the outside. The sound holes 121a are each positioned at an eccentric location offset in the B1-direction from a central axis of the structure portion. A sound pressure level of the acoustic signal AC2 that is emitted from the sound holes 123a into a first space is lower than a sound pressure level of the acoustic signal AC2 that is emitted from the sound holes 123a into a second space.
