Devices, methods, and systems are described for an anti-feedback audio device (100) comprising a dipole speaker (110) having an acoustically null sound plane (115) or acoustically null sound area (117), a first microphone (120) disposed substantially within the acoustically null sound plane (115) or acoustically null sound area (117), and a neural network (130) communicatively coupled to the dipole speaker and the first microphone (120) such that a first output from the first microphone is communicated to the neural network (130) for processing, and a second output from the neural network (130) is communicated to the dipole speaker (110). The combination of the dipole phase cancellation and the neural network gives an unexpected result of an extremely high signal-to-noise ratio for speech over noise.

In non-limiting examples of the present disclosure, an electrical receptacle is provided. A first transmission tab configured to be electrically connected to a neutral terminal of the electrical receptacle is provided. A second transmission tab configured to be electrically connected to a live terminal of the electrical is provided. A speaker device in electrical communication with the first and second transmission tabs and a speaker grille cover secured to the receptacle cover are also provided, Other examples of the present disclosure relate to systems, methods and devices for influencing resonant modes of one or more vibrating surface, including a mode throttling device and an exciter device.

The present disclosure provides a vibration sensor including a vibration assembly including a mass element and an elastic element, a first acoustic chamber, an acoustic transducer, and a buffer member. In response to an external vibration signal, the vibration assembly vibrates such that a volume of the first acoustic chamber changes. The acoustic transducer is in communication with the first acoustic chamber. In response to a volume change of the first acoustic chamber, the acoustic transducer may generate an electrical signal. The buffer member is connected to the mass element or the elastic element. The buffer member reduces an impact force of the mass element acting on the elastic element during a vibration process of the vibration assembly. The acoustic transducer has a first resonance frequency, the vibration assembly has a second resonance frequency, and the second resonance frequency is less than the first resonance frequency.
