Abstract

The invention discloses a voice acquisition device and a household appliance. The voice acquisition device comprises a microphone assembly, wherein the microphone assembly comprises a microphone sleeve and a microphone; the microphone sleeve is provided with a microphone hole and a sound cavity which are connected to each other; the diameter of the microphone hole is smaller than that of the soundcavity; the microphone is contained in the sound cavity; and a cavity for limiting a frequency response resonance point of the microphone in the pitch frequency range of the male sound or the femalesound is arranged between the microphone and the microphone hole. According to the voice acquisition device provided by the embodiments of the invention, the sound cavity is arranged for the microphone, the frequency response resonance point of the microphone is limited in the pitch frequency range of the male sound or the female sound, a sound cavity resonance mode is adopted to amplify the voiceof a person for multiple times, signals and noise of other frequencies are amplified or attenuated, and the gain of the voice signals is greatly improved, so that a voice recognition distance is increased, and thus a voice control distance of voice control equipment is increased, and the convenience for voice control is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a voice collection device and household appliances. Background technique [0002] With the development of voice recognition technology, voice control (referred to as voice control) is gradually applied to various electronic devices, especially home appliances are more and more widely used. Using voice recognition technology, users can easily control various home appliances by issuing simple voice commands. For example, users can control air conditioners, fans, lights and other home appliances through voice commands in bed while sleeping. You can control TV, stereo, water heater and other home appliances through voice commands, which provides great convenience for users' lives. [0003] In the home application environment, the noise interference is usually small, and a strong noise reduction effect is not required, but sufficient sound control distance is required. However, ...
