1.Horn Speakers are small products for electroacoustic conversion
The horn loudspeaker is an electroacoustic transducer. A speaker is an electro-acoustic transducer that can convert electrical signals into mechanical vibrations and then into acoustic signals. The basic structure diagram of a conical speaker is not complex, and there are not many components, making it a small product. But it fulfilled a wish that humans have had for thousands of years, to replay the sound. This song should only be heard on the surface of the sky, so that people can hear it a few times. "The emergence of modern recording technology and speakers has dispelled Du Fu's regret, and the heavenly sound of famous artists, instruments, and songs has become permanent in the world with the emergence of speakers.
2. Speakers are an indispensable product in modern people's lives.
PA Loudspeakers is a product that cater to both refined and popular tastes, and are accessible from top to bottom. Loudspeakers serve both astronomical and trivial matters; Speakers undertake the transmission of language, music, and other related tasks, which are related to life, activities, culture, and wisdom; And it itself is exceptionally simple and low-key, making it one of the most cost-effective products and the most beautiful invention of the 20th century. In modern life, speakers are everywhere. Due to its low-key and affordable nature, people often overlook its existence. It can be imagined that if the speaker suddenly disappears one day, it will have a catastrophic impact on modern human life, and its importance can be felt.
3. Yang's microphone is a device that converts energy twice
In modern society, most electronic products are an energy conversion. If an electric motor converts electrical energy into mechanical energy; Generators convert mechanical energy into electrical energy. The speaker is an electro-acoustic transducer that converts electrical signals into mechanical vibrations, and then converts mechanical vibrations into acoustic signals, achieving two conversions. The two conversions increased the difficulty of research and analysis. The total efficiency of two simultaneous conversions is the product of each conversion efficiency, resulting in a decrease in total efficiency. The speaker is therefore an inefficient product.
4. The speaker is a versatile instrument
There are hundreds or thousands of musical instruments in the world, including wind instruments, string instruments, percussion instruments, and keyboard instruments. Each instrument has its unique timbre and performance characteristics, which cannot be replaced by each other. Some oral performers may imitate certain musical instruments, and people express their approval out of tolerance, but these imitations are still quite different from the original instrument. Only loudspeakers can handle various musical instruments to the satisfaction of most professionals and amateurs, but it is only because people are accustomed to seeing and listening that they do not notice their magic.
5. Speakers are both scientific and artistic products
Imperial examination: It refers to something that can be experimentally verified, theoretically deduced, and logically justified. Artistic: Some content is imaginative, illogical, and difficult to derive and verify. The principle, structure, design, and manufacturing of speakers are scientifically sound and undisputed. However, when using the same speaker for playback, different people may have different feelings; Many feelings are difficult to express. Different speakers have different personalities, which is different from other electromechanical devices. A complex computer that operates according to a program and has the same results for different people. The listening of speakers will have different effects and feelings under the same conditions. Scientific explanations are often insufficient, and sometimes artistic explanations are needed. It seems that speakers may have some vitality and vitality.
6. Speakers have scientific, artistic, and entertaining properties. In addition to scientific and artistic properties, speakers also have entertainment properties.
Entertainment refers to randomness, unpredictability, aimlessness, and no need for verification. Anyway, happiness is enough. In the process of the formation and development of audio equipment such as speakers, there are many enthusiasts of audio equipment, even enthusiasts of audio equipment, known as audio enthusiasts. They have devoted themselves with great enthusiasm, abundant energy, and a continuous stream to the "audiophile" industry, which has contributed immensely to the development of the audio industry. But most of them are not from a professional background in audio, just out of their love and persistence in audio, they may form some unique opinions and practices. For example, if you think that changing the power cord can improve the sound quality, he feels it, but you may not feel it. Son is not a fish, how can one know the joy of fish? If we view it as play, as a game, as entertainment, all problems will be solved easily.
7. Speaker is a multi-dimensional product
The speaker is a three-dimensional product, and the geometric shapes of the X, Y, and Z axes are different, which will have an impact on performance. The performance of a speaker is related to time, and there is a transient effect first. When an audio signal is input to the speaker, it will sound, but there is a delay. Interrupting the audio signal input to the speaker will stop the sound, but there will be a delay. The speaker output varies for signals of different frequencies. The same geometric shape and structure of the speaker, as well as the different composition and physical characteristics of the materials used, can also affect the final playback effect. Unlike other equipment used in conjunction with speakers, the sound production effect may vary significantly depending on the environment in which the sound is produced. This all indicates that the speaker is a multidimensional and diverse product.
8. Speakers involve numerous disciplines
The diaphragm involves almost all materials (biological, plant, chemical, synthetic, cutting-edge materials): it is made from the most commonly used and common materials, such as pulp; It is made from the most expensive and scarce materials, such as gold and diamond; It is made from the most commonly used polymer materials, such as polypropylene residue; It uses the most advanced rocket missile materials, such as fine ceramics; To analyze the low order harmonics of speakers, we also cite the cutting-edge mixing theory.
9. Speakers are products that create happiness while also producing sound violence
From cultural, sociological, and psychological perspectives, speakers are products that create happiness. People watch movies, listen to plays, listen to music, sing, and speakers serve people's happiness. Speakers are products that create happiness, which some people didn't realize at first. Once enlightened, consensus is quickly gained. However, in the widespread application of speakers, a phenomenon called acoustic violence has emerged. In some sound reinforcement occasions, some people increase the volume extremely, and the audience feels a very vibrating stimulation. But I don't know that this high sound pressure level can lead to hearing loss. Due to the ignorance of the parties involved, the drive of commercial interests, and the absence of regulation, this kind of vocal violence is regarded by some as the norm.
