  • Publication number: 20230202405
    Abstract: The present invention relates to a vehicle door, which is installed on the vehicle. The door includes a shutter, a speaker and an inverted tube. The shutter has an accommodation cavity, and the speaker is installed in the shutter. The inverted tube is located in the accommodation cavity, with one end connected with the interior of the vehicle, and the other end forming an acoustic port with a flange. The inverted tube exports the sound from the rear cavity into the car. The inverted tube with the acoustic port can strengthen the resonance effect of the air, and strengthen the sound wave. It can improve the loudness of the speaker, reduce the noise of the airflow, and effectively improve the sound quality of the speaker.

  • Publication number: 20230199371
    Abstract: The present application provides a sounding device. The sounding device includes a front surface with a sound outlet hole; a back surface; a sounding component and an outer casing. The outer casing is covered outside the sounding component. A cavity is formed between the outer casing and the end of the sounding component close to the back side. A sound guiding channel is arranged in the outer casing. One end of the sound guiding channel is communicated with the sound outlet hole, and the other end of the sound guiding channel is communicated with the cavity. The sounding device of the present application provides a smooth transmission channel for the sound from the back side by arranging the sound guiding channel in the outer casing, thereby strengthening the frontal sound of the sounding device and greatly improving the loudness of the sounding device.

  • Patent number: 11516590
    Abstract: A sounding device includes a bracket having a receiving space, a vibration system, and a magnetic circuit unit. The magnetic circuit unit drives the vibration system to vibrate. The magnetic circuit unit includes a first magnetic body, a second magnetic body, and a yoke. The yoke includes a bottom wall, a first sidewall, and a second sidewall. The first sidewall and the second sidewall is fixed to the bracket. The first sidewall and the bottom wall form a first groove accommodating the first magnetic body, and the second sidewall and the bottom wall from a second groove accommodating the second magnetic body. An opening of the first groove is oriented opposite to an opening of the second groove. The vibration system includes first and second vibration portions. The magnetic circuit unit is arranged between the first and second vibration portions. In this way, a thin sounding device can be realized.
