一种革新的蓝牙音响设计：变音形式的音乐创作

。

TRS研究所首先提出了一种革命性的蓝牙音响设计，可以实现变音形式的音乐创作。研究人员表示，该设计可以克服传统音响设计中存在的声音污染问题，同时还能降低背景噪声。

在传统的音响设计中，音乐是由一个或多个扬声器播放的，声音从扬声器中直接传到耳朵。这种设计存在一个主要问题，那就是声音污染。声音污染可以通过声音反射和声音折射来描述，它可以让人感到烦闷和分心。声音污染分为两类，一类是室内声音污染，由于扬声器的振动传到家具、墙壁、地板等，反射回来干扰了人的听觉；另一类是室外声音污染，扬声器的声音会反射到周围的物体，如街道、楼房、车辆等，形成声音分散，让人感到吵杂。除了声音污染，噪声也会干扰人的听觉。

研究人员在传统扬声器设计中加入了一个新元素——变音器。变音器的作用是调节声音的频率，让声音的频率与周围环境相匹配。这样，声音的反射和折射就会减少，声音污染就会减弱。变音器由一个扬声器、一个电子调节器和一个音频转换器组成，它们的工作原理如下：首先，声音由扬声器发出；然后，电子调节器调节声音的频率；最后，音频转换器将声音转换为可以传到耳朵的信号。

研究人员表示，变音器的设计可以克服声音污染和背景噪声的问题，让人们能够更好地欣赏音乐。该设计还可以应用到其他领域，如影院、酒吧、演唱会等场所。

The TRS research institute first proposed a revolutionary Bluetooth speaker design that can realize the creation of music in the form of vowel transformation. Researchers said the design can overcome the sound pollution problems inherent in traditional speaker design while also reducing background noise.

In traditional speaker design, music is played by one or more speakers, and sound is directly transmitted from the speaker to the ear. This kind of design has a major problem, that is, sound pollution. Sound pollution can be described by sound reflection and sound refraction, which can make people feel bored and distracted. Sound pollution is divided into two types: one is indoor sound pollution, which is caused by the vibration of speakers transmitted to furniture, walls, floors, etc., and reflected back to interfere with people's hearing; the other is outdoor sound pollution, which is caused by the sound of speakers being reflected by surrounding objects such as streets, buildings, and vehicles, resulting in sound dispersion, which makes people feel noise. In addition to sound pollution, noise can also interfere with people's hearing.

Researchers have added a new element-changer-to traditional speaker design. The function of the changer is to adjust the frequency of the sound so that the frequency of the sound is matched with the surrounding environment. In this way, the reflection and refraction of sound will be reduced, and the sound pollution will be weakened. The changer consists of a speaker, an electronic regulator, and an audio converter. Their working principle is as follows: first, the sound is emitted by the speaker; then, the electronic regulator adjusts the frequency of the sound; finally, the audio converter converts the sound into a signal that can be transmitted to the ear.

Researchers said the design of the vowel can overcome the problems of sound pollution and background noise, so that people can better appreciate the music. The design can also be applied to other fields, such as theaters, bars, concerts, etc.
