[0021] As described in the background art, large moving coil speakers have strong mid-bass performance but lack mid-high, high, and ultra-high frequency performance. Some ordinary large headphones also have a large moving coil speaker + a high-frequency moving coil speaker to compensate for high frequencies with the high-frequency moving coil. However, since the positions of the large moving coil speaker (mid-low frequency performance) and the high-frequency moving coil speaker are not on the same axis, there will be a left-right difference in sound performance.

[0022] To solve this technical problem, the present utility model provides a headphone with an array frequency division speaker;

[0023] It includes a housing 1. A hollow mounting base 3 is fixed at the center inside the housing 1. A large moving coil 5 for mid-low frequency performance is arranged inside the hollow mounting base 3. A noise reduction microphone 4 is arranged at the center of the upper end of the hollow mounting base 3. A speaker unit 6 is arranged at the upper end of the hollow mounting base 3 and outside the noise reduction microphone 4.

[0024] In the headphone with an array frequency division speaker provided by the present utility model, multiple speaker units 6 are arranged in a circular array with the noise reduction microphone 4 as the axis, so that the sound performance of this headphone can be more integrated, better reflecting the depth of the sound. There is no left-right difference in sound performance. And the speaker unit 6 is any one or more of a high-frequency moving coil speaker, a high-frequency flat panel speaker, and a ceramic piezoelectric speaker. Thus, this headphone has a wide frequency response range, clear and natural sound quality, a smooth response frequency, high-quality sound, and extremely excellent compliance and resolution, being able to fully display the charm of music.

[0025] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments of the present utility model can be combined with each other.
