The application relates to the technical field of mobile communication, and discloses a filter and a communication device. The filter comprises a cavity, a cover plate and a resonator assembly. The cover plate is arranged on the cavity. The resonator assembly comprises a first resonator and two second resonators. The first resonator is connected with the side wall of the cavity, the first resonator is located between the two second resonators, each second resonator is independently connected with the bottom wall of the cavity or the cover plate, the extension direction of the first resonator is arranged at an angle with the extension direction of the second resonator, the first resonator and the second resonator are coupled and connected, and the two second resonators are coupled and connected. The filter and the communication device have the advantages that a flying rod does not need to be arranged between the two second resonators, one resonant cavity can be omitted, the overall size of the filter is smaller, the miniaturization requirement of the product can be met, and the material cost is reduced. In addition, when the flying rod is omitted, the adverse effect on the far-end suppression can be avoided, and the performance of the product is improved.

A music synthesizer generates an audio signal using an assembly comprising hundreds or thousands of resonators. These resonators may be based on the analysis of any acoustic space, such as acoustic musical instruments, rooms, recording studios, or music halls. A machine learning network is trained to learn features of the music sound. The feature may be whether the sound is melodious. The network produces an audio effect applied to a selected frequency in the spectrum. An input signal or an excitation signal is provided to the network that processes the input by a trained model of the target audio source and configures the resonator components to generate an output audio signal based on the input signal. The network may be expanded to create novel impulse responses to create tones and timbres unique to existing audio sources, which input signals may include musical tones or include human voice inputs.

Provided in the present invention is a notch filter. The notch filter comprises a signal input end, first laterally excited bulk acoustic wave resonators connected in series with the signal input end, resonator assemblies connected in parallel to the first laterally excited bulk acoustic wave resonators, and a signal output end connected in series with the first laterally excited bulk acoustic wave resonators, wherein each resonator assembly comprises two second laterally excited bulk acoustic wave resonators that are respectively grounded; a first laterally excited bulk acoustic wave resonator is connected between two second laterally excited bulk acoustic wave resonators in a resonator assembly, and the three laterally excited bulk acoustic wave resonators are jointly arranged in a T shape; and the resonant frequency of each first laterally excited bulk acoustic wave resonator is less than the resonant frequency of each second laterally excited bulk acoustic wave resonator. In the present invention, by means of designing first laterally excited bulk acoustic wave resonators that are connected in series and resonator assemblies that are connected in parallel, a notch filter for realizing high-frequency, high-degree-of-suppression and large-bandwidth filtering is obtained.
