Description
本发明涉及认知和电声的技术领域，具体地，涉及利用可听声波的便携生物情绪调控装置及方法。
在人类日常生产和生活中，声波处处存在，并且时常对人们的情绪产生影响。例如，舒缓的音乐可以使人们放松和平静；刺耳的警报声或者尖锐的刮玻璃声通常使人们警惕和烦躁。现有研究表明，白噪声(white noise)或粉红噪声(pink noise)这类覆盖人的整个听觉范围(20-20000Hz)且在各个频率上由相同能量密度的单调声音刺激，作为听觉刺激，使脑电δ节律增加，使人平静且产生睡意。另外，研究发现不同节奏的单音节音频对SD大鼠播放时，SD大鼠的行为学、体重、糖水偏好率、海马体5-HT和DA浓度、海马体多巴胺D2受体均随节奏的不同有着不同的变化。可见相应的可听声波对人动物的情绪都会产生一定的影响。除此之外，某些频率下的次声和超声声波也会对人和动物的情绪产生影响，例如研究表明，低强度频率为7Hz左右的次声作用在人耳时，可使人烦躁，且表现出非特异性的应激反应及神经内分泌失调等症状。
幅度调制是一种信号调制方法，它是一种使载波的振幅按照所需传送信号的变化规律而变化，但频率保持不变的方法，广泛应用于信号的传输。而幅度调制过程是指用低频信号直接控制高频振荡的振幅，使高频信号具有低频信号的特性，并因此把低频信号称为调制信号或调制波，高频振荡称为载波，经过调制后的高频振荡称为已调波。调幅系统成本低廉，且容易产生及恢复信号。因此可以通过调幅的方式使次声或超声这种本不可听频率范围的声波加载到高频信号上，使之转变为可听声波。
现有技术方面，如今广泛采用经颅电刺激法进行人的情绪调控。经颅电刺激是一种非侵入性神经刺激技术，它通过电极将特定的低强度电流作用于特定脑区，达到调节大脑皮层神经活动的目的。这项技术已经开始应用于临床精神类疾病的治疗， 也在人的情绪调控以及行为调控方面有所应用。但是，经颅电刺激的方法也有一定的局限性，它是一种接触式的调控方法，其电极需要贴在人或动物的头皮上方可起作用，并且需要人和动物处于一种相对平静的状态。但是，若使用声波来对人或动物进行情绪的调控，不仅可以避免接触，而且对人或动物的活动状态没有要求，是一种更加方便且广泛可行的情绪调控方式。
在公开号为CN108873940A的专利文献中公开了基于声波检测的情绪互动系统，包括无人机，无人机包括无人机飞行系统，以及与无人机飞行系统连接的北斗模块和飞行线路数据库，以及与无人机飞行系统连接处理器单元，所述处理器单元的供电接口连接有蓄电池模块，处理器单元的数字信号输出端连接有语音播报模块和视频显示模块，处理器单元的数字信号输入端连接有声波检测模块，处理器单元的串行总线连接有存储模块。该基于声波检测的情绪互动系统，在住户返回家中后发出声响，声波检测模块快速获取住户发出的声响，之后通过处理器单元开启无人机飞行系统，控制无人机飞行到住所门口位置迎接住户，通过显示模块显示表情以及通过语音模块播放问候语音。
因此，需要提出一种新的技术方案。
