Preferably, the sound emitting unit emits white noise or music.

Preferably, the window glass is a multiple layer glass.

The beneficial effects of the utility model reside in that:

1. the sound production unit vibrates to drive the transparent vibrating plate to vibrate so as to produce sound, and the amplitude and phase of sound waves produced by vibration are the same as those received by the first sound pickup or the second sound pickup, so that the purpose of active noise reduction is achieved, noise reduction can be performed on noise with most frequencies, and the noise reduction effect is good;

2. the audio input accessory is used for inputting audio signals to the processor, and the sound production unit is used for driving the transparent vibrating plate to vibrate, so that white noise such as bird calling, rain thunder and the like or sound scenes such as music and the like can be produced, and the sound outside the window in a natural state can be simulated.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings attached to the specification of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict. The examples given are only for explaining the invention and are not intended to limit the scope of the invention.

The utility model provides a window of making an uproar falls in initiative, includes window frame 1, sound generating unit 2, audio input accessory 3, first adapter 4 and second adapter 5, be equipped with multilayer window glass 6 and transparent vibration board 7 in the window frame 1 parallelly, transparent vibration board 7 is organic glass. The sound production unit 2 has two, locates respectively transparent vibration board 7 with lean on the position of window frame 1 top and bottom between the window glass 6, sound production unit 2 includes electromagnetism moving coil group 21 and magnet line group 22, and this magnet line group 22 is permanent magnet or electromagnet line group 22, electromagnetism moving coil group 21 locates on the right flank of transparent vibration board 7, magnet line group 22 locates transparent vibration board 7 with between the window glass 6, and with window frame 1 fixed connection.

First adapter 4 is located the right flank of window frame 1, second adapter 5 with audio input accessory 3 locates the left surface of window frame 1, be equipped with treater 8 in the window frame 1, first adapter 4, second adapter 5 with sound production unit 2 all with treater 8 is connected, treater 8 passes through the power 9 power supply.
