Problems solved by technology

[0002] Current beds and spring mattresses adopt a so-called "pocket spring" structure in order to avoid discomfort such as noise caused by the mutual friction between the support springs of the spring liner, that is, each support spring is covered with a fabric bag, and the fabric The bags are connected to each other. Although such a structure can reduce noise to a certain extent, due to the complicated structure of the bags and the complicated production process, the production cost will increase.
And the noise reduction effect is limited

Embodiment Construction

[0011] Such as figure 1 As shown, the noise reduction bed includes feet, bedside boards supported by the feet, keels connected between the bedside boards, and a plurality of sound sensors as detection units. figure 1 Only four sound sensors 1-4 are schematically shown, and they are respectively located at the connection between the bedside board and the keel and the connection between the keels. Preferably, a connection mechanism is included between the feet and the bed board, and there are other sound sensors disposed close to the top of the connection mechanism.

[0012] The noise reduction bed also includes an active noise reduction module arranged near the detection unit, the active noise reduction module includes a control unit, a noise acquisition unit, a noise classification unit, a switch matrix, an envelope analysis unit, an envelope processing unit, The first inverse spectrum generation unit, the noise spectrum generation unit, the noise spectrum processing unit, th...

Abstract

The invention provides an active noise reduction bed for improving the comfort level of a bed and building high-quality quiet sleep environment. The noise reduction bed comprises legs, bedside plates supported by the legs, keels connected between adjacent bedside plates, and a plurality of detection units, and also comprises active noise reduction modules arranged nearby the detection units. The active noise reduction bed reduces and eliminates noises generated due to friction of connections of the bed plates and a bed body and especially connections of the bed legs and the bed plates, and improves the user experience.

Description

technical field [0001] The present invention relates to the technical field of noise reduction, and more specifically relates to an active noise reduction bed. Background technique [0002] Current beds and spring mattresses adopt a so-called "pocket spring" structure in order to avoid discomfort such as noise caused by the mutual friction between the support springs of the spring liner, that is, each support spring is covered with a fabric bag, and the fabric The bags are connected to each other. Although such a structure can reduce noise to a certain extent, the production cost is increased because the bag structure is relatively complicated and the production process is complicated. And the noise reduction effect is limited. Contents of the invention [0003] In order to improve the comfort of the bed and create a high-quality quiet sleeping environment, the present invention provides an active noise reduction bed. The noise reduction bed includes feet, bedside boards...
