Definitions

  • the invention relates to the technical field of electroacoustic products, and in particular relates to an active noise reduction loudspeaker component of a headset.
  • a headset can transmit the sound made by the electronic device directly to the ears, which reduces the influence of external noise on the sound effect and makes the sound heard more clearly.
  • the active noise reduction headset on the market is generally high in cost, heavy in weight and large in volume because a noise reduction device and a loudspeaker need to be disposed separately.
  • a light and dexterous active noise reduction loudspeaker component of a headset capable of reducing cost is urgently needed to entirely reduce the volume of the headset and reduce the cost of the headset.
  • a technical problem to be solved by the invention is to provide a light and dexterous active noise reduction loudspeaker component of a headset capable of reducing the cost, so as to entirely reduce the volume of the headset and reduce the cost of the headset.
  • the active noise reduction loudspeaker component of the headset comprises a loudspeaker frame, wherein the middle of the loudspeaker frame has a housing hole; a loudspeaker magnet housed into the housing hole; a loudspeaker coil positioned in a groove of the loudspeaker magnet; a loudspeaker diaphragm covered at an opening end of the loudspeaker frame; a noise reduction circuit board fixed to the back surface of the loudspeaker frame; and a noise reduction microphone connected to the noise reduction circuit board through a microphone line and installed near the loudspeaker frame, wherein a gap among the loudspeaker frame, the loudspeaker magnet, the loudspeaker coil and the loudspeaker diaphragm forms an acoustic cavity.
  • the side edge of the loudspeaker frame is provided with a microphone placing groove to house the noise reduction microphone.
  • the noise reduction microphone is vertically placed in the microphone placing groove relative to the loudspeaker frame; and a sound absorbing surface of the noise reduction microphone faces or backs on to the loudspeaker magnet.
  • the noise reduction microphone is placed in the microphone placing groove in parallel relative to the loudspeaker frame; and a sound absorbing surface of the noise reduction microphone faces the same or opposed direction with an opening of the loudspeaker frame.
  • the microphone placing groove and the loudspeaker frame are integrated in one piece.
  • the noise reduction microphone is installed on the center of the loudspeaker magnet, and faces or backs on to the loudspeaker magnet.
  • loudspeaker covers are covered at the opening end of the loudspeaker frame and outside the loudspeaker diaphragm; and the loudspeaker covers are provided with housing grooves for housing the noise reduction microphone and the microphone line.
  • the number of the noise reduction microphone is one or two.
  • the loudspeaker frame is a plastic part.
  • the loudspeaker circuit board is an annular plate which is adapted with the shape of the loudspeaker frame.
  • the noise reduction component is simplified as a circuit board and a noise reduction microphone.
  • the circuit board is installed on the loudspeaker frame, thereby simplifying the structure, reducing the volume of the product and effectively reducing the cost.
  • the side edge of the loudspeaker frame is provided with the microphone placing groove to house the noise reduction microphone, thereby enhancing structure stability and integration degree.
  • the microphone placing groove and the loudspeaker frame are integrated in one piece, thereby enhancing structural integration degree and reducing installation difficulty.
  • the noise reduction microphone is installed on the center of the loudspeaker magnet, and faces or backs on to the loudspeaker magnet, so as to play a best noise reduction effect.
  • the loudspeaker circuit board is an annular plate which is adapted with the shape of the loudspeaker frame, so that the effect of the acoustic cavity is better.
  • the first embodiment of the invention provides an active noise reduction loudspeaker component of a headset, mainly comprising a loudspeaker frame 110, a loudspeaker magnet 130, a loudspeaker coil 150, a loudspeaker diaphragm 170, a noise reduction circuit board 210 and a noise reduction microphone 230.
  • the middle of the loudspeaker frame 110 has a housing hole 112.
  • the loudspeaker magnet 130 is housed into the housing hole 112.
  • the loudspeaker magnet 130 is circular, and the shape of the housing hole 112 is adapted with the loudspeaker magnet 130.
  • the loudspeaker coil 150 is positioned in a groove 132 of the loudspeaker magnet 130.
  • the loudspeaker diaphragm 170 is covered at an opening end of the loudspeaker frame 110.
  • the noise reduction circuit board 210 is annular, and is adapted with the shape of the loudspeaker frame 110.
  • the noise reduction circuit board 210 is fixed to the back surface of the loudspeaker frame.
  • the noise reduction microphone 230 is connected to the noise reduction circuit board 210 through a microphone line 220 and is installed near the loudspeaker frame 110.
  • the side edge of the loudspeaker frame 110 is provided with a microphone placing groove 114 to house the noise reduction microphone 230.
  • the noise reduction microphone 230 is vertically placed in the microphone placing groove relative to the loudspeaker frame 110; and a sound absorbing surface of the noise reduction microphone 230 faces or backs on to the loudspeaker magnet 130.
  • a gap among the loudspeaker frame 110, the loudspeaker magnet 130, the loudspeaker coil 150 and the loudspeaker diaphragm 170 forms an acoustic cavity.
  • the microphone placing groove 114 and the loudspeaker frame 110 are integrated in one piece.
  • the second embodiment of the invention provides an active noise reduction loudspeaker component of a headset, and is different from the first embodiment in that the noise reduction microphone 230 is vertically placed in the microphone placing groove 114 relative to the loudspeaker frame 110, and a sound absorbing surface of the noise reduction microphone 230 faces the loudspeaker magnet 130.
  • the third embodiment of the invention provides an active noise reduction loudspeaker component of a headset, and is different from the first embodiment and the second embodiment in that the noise reduction microphone 230 is placed in the microphone placing groove 114 in parallel relative to the loudspeaker frame 110, and the sound absorbing surface of the noise reduction microphone 230 faces the same direction as the opening of the loudspeaker frame.
  • the fourth embodiment of the invention provides an active noise reduction loudspeaker component of a headset, and is different from the third embodiment in that the noise reduction microphone 230 is placed in the microphone placing groove 114 in parallel relative to the loudspeaker frame 110, and a sound absorbing surface of the noise reduction microphone 230 faces the opposed direction to the opening of the loudspeaker frame.
  • the fifth embodiment of the invention provides an active noise reduction loudspeaker component of a headset, and is different from the above embodiments in that the noise reduction microphone 230 is installed on the center of the loudspeaker magnet 130, and faces or backs on to the loudspeaker magnet. As shown in the figure, the noise reduction microphone 230 faces the loudspeaker magnet 130. It should be understood that in other embodiments, the noise reduction microphone 230 can also back on to the loudspeaker magnet 130. Loudspeaker covers 190 are covered at the opening end of the loudspeaker frame 110 and outside the loudspeaker diaphragm 170. The loudspeaker covers 190 are buckled with the loudspeaker frame 110, and the loudspeaker covers 190 are provided with housing grooves 192 for housing the noise reduction microphone 230 and the microphone line 220.
  • the embodiments listed in part of the Detailed Description are in this case that the number of the noise reduction microphone is 1, but it should be understood that the number of the noise reduction microphones can also be 2 in order to enhance the noise reduction effect.
  • the loudspeaker frame and the loudspeaker covers involved in the above embodiments are plastic parts.
