  • Speaker, audio device thereof, and method of regulating frequency response
    Patent number: 10805724
    Abstract: The invention provides a speaker, an audio device thereof, and a method of regulating frequency response. The speaker comprises a back cavity and a magnetic circuit system connected to the back cavity, and further comprises: an intermediate-frequency frequency response regulation module disposed in the back cavity for regulating a length of a first effective air passage of the back cavity where an air flow passes, such that a resonant frequency of the back cavity is equivalent to a frequency of intermediate-frequency frequency response of the speaker to be improved; and/or a high-frequency frequency response regulation module disposed in the back cavity for regulating a length of a second effective air passage of the back cavity where the air flow passes, such that the resonant frequency of the back cavity is equivalent to a frequency of high-frequency frequency response of the speaker to be improved.
