Translated fromChinese技术领域technical field
本发明涉及枕头技术领域，尤其是指一种音波共振系统。The invention relates to the technical field of pillows, in particular to a sound wave resonance system.
背景技术Background technique
在居家床品中，枕头是不可或缺的物件。对枕头应用合适的设计和材质，有助于给使用者提供舒适的体验。另一方面，合适的音乐具有一定的放松减压效果。将音乐与枕头功能结合起来的音乐枕，应当充分利用音乐的特性实现放松效果。进一步地，若将音乐的听感、触感统一起来，实现音波与人体体细胞、听觉神经的同时刺激，在合适的条件下可有放松效果。不过目前这一领域存在的问题是，在传统设计中，音波共振影响使用者侧躺，会对耳部造成不适。此外，现有音乐枕调低音量，音波共振的强度也往往减弱，若调高音量，音波共振强度则跟着增强，这样不能独立调节音量与共振强度，给使用者带来不便；同时现有产品没有提供适于音波共振的音源方案，由此使用者不得不自己挑选音乐，但是未经筛选验证的音乐包含的共振低频成分较少，会削弱音波共振带来的放松效果。Pillows are an indispensable item in home bedding. Applying the right design and material to the pillow helps provide a comfortable experience for the user. On the other hand, appropriate music has a certain relaxing and stress-reducing effect. Music pillows that combine music and pillow functions should make full use of the characteristics of music to achieve a relaxing effect. Further, if the listening and tactile sensations of music are unified, the simultaneous stimulation of sound waves, human body cells and auditory nerves can be achieved, and a relaxing effect can be achieved under suitable conditions. However, the current problem in this field is that in the traditional design, the sound wave resonance affects the user's side lying, which can cause discomfort to the ears. In addition, when the volume of the existing music pillow is lowered, the intensity of the sonic resonance is often weakened. If the volume is turned up, the sonic resonance intensity will also increase, so that the volume and the resonance intensity cannot be adjusted independently, which brings inconvenience to the user; at the same time, the existing product There is no sound source solution suitable for sonic resonance, so users have to choose music by themselves, but music that has not been screened and verified contains less resonant low-frequency components, which will weaken the relaxation effect brought by sonic resonance.
