2024-01-02 The company's requirements for loudspeaker production line production The company requires the production line to improve production efficiency, reduce unnecessary cost losses, improve the yield of products, and produce in strict accordance with product production standards. Employees strengthen technical learning, master technical essentials, maintain production equipment, and avoid production line stop due to equipment problems. It is also necessary to ensure safe production, and employees must strictly implement safety inspections as required, so as to achieve the basic three steps of safety inspection before production, safety production during production, and safety inspection at the end of production. Periodically check the safety of the equipment to avoid aging and wear, and replace the equipment in time to eliminate security risks.

2023-12-25 Summary of the Company's Work on Speaker Production Process Meeting summary 1.Production lines should improve production capacity, reduce common production errors, strictly control production safety, reduce potential safety hazards, and achieve safe production with zero potential hazards. 2.The quality inspection department should strictly control the quality problems of products, ensure that unqualified products are not kept out of the warehouse, that unqualified products are investigated by people, and that unqualified products are handled in time, reduce the probability of unqualified products reaching customers, and strive to achieve zero customer complaint standards on product quality problems. At the same time, a large number of unqualified products with the same problem should be fed back in time, and the reasons should be found in time to reduce the subsequent production costs. 3.Technical departments should pay attention to product problems and solve them in time, and at the same time pay attention to the latest technical problems in the industry, update the company's production technology, and optimize the company's production efficiency from the technical level. 4.In terms of business, we should communicate with customers in time, understand customer needs, give feedback to the company in time for the pr

2022-06-03 Audio Instrument-Loudspeaker Loudspeaker, also called speaker, in sound reproduction, device for converting electrical energy into acoustical signal energy that is radiated into a room or open air. The term signal energy indicates that the electrical energy has a specific form, corresponding, for example, to speech, music, or any other signal in the range of audible frequencies (roughly 20 to 20,000 hertz). The loudspeaker should preserve the essential character of this signal energy in acoustical form. This definition of a loudspeaker excludes such devices as buzzers, gongs, and sirens, in which the acoustical signal energy does not correspond in form to the electrical signal. The part of the speaker that converts electrical into

2022-05-31 Some Knowledge about Subwoofers Subwoofers are certainly important, especially in home theater systems. These days, few people have a two-channel [music only" system with full range speakers and no subwoofer, so listening to a sub is part of the overall equation. Use the guidelines for evaluating bass quality, extension and clarity that we previously outlined, but add a few more for a subwoofer. Perhaps the most important thing about a subwoofer`s sound will be its ability to play loudly enough for your needs without noise or audible distress. Once you have determined that the sub in question has the quality of sound you`re looking for (by listening to it with music), you need to determine if it has the quantity of sound as well. Play a movie soundtrack with a lot of deep bass special effects-explosions, crashes, dinosaur roars, etc. Play the movie slightly louder than you think you`d ever play it. Listen to the bass-does the sub fill the room with clean output or is it weak and struggling? If it sounds good, then replay the same sequence again-only this time, turn off all the other speakers and listen just to the sub by itself. Does it sound pretty clean, without any really noticeable distortion and is it free from severe distracting mechanical noises? It`s ok if there`s a little audible distortion and a small bit of mechanical noise, because remember, this is at a level higher than you`ll ever really play the system and when the other speakers are playing, they`ll mask th

2022-05-28 The Importance of Loudspeaker's Frequency Response If you're going to understand anything about audio-how speakers work, the effect of room acoustics, how to set your subwoofer's level, the concept of bass management/low-pass filters, anything about audio-you have to understand frequency response. This is the cornerstone of everything in audio. It all starts and stops with frequency response. Amplifiers, receivers, speakers, CD and DVD players, they all have to have as close to perfect frequency response as possible, or else they just won`t sound right. Nothing else matters if the frequency response is no good. Can't make it any clearer than that. An audio device with good frequency response is able to play all the low, middle, and treble tones correctly-and in the proper proportion to each other-and that's what tells our ears whether or not this is a high-fidelity unit with rich, vibrant, lifelike sound.

2022-05-27 How to Evaluate Loudspeakers for Sound and Accuracy What do we really mean when we talk about a loudspeaker`s [sound?" When we hear a speaker, how do we know by simply listening to it whether or not it`s a good speaker? What should we listen for? Obviously, a speaker`s job is exactly the same as any other audio component, like an amplifier or disc player-its job is to reproduce the input signal as accurately as possible, with minimal distortion or deviation from the original. Loudspeakers are the least perfect of audio devices. But because they are transducers-they convert one kind of input (in this case an electrical signal) into a different kind of output (acoustic sound waves)-they have a more difficult job than an amplifier or CD player. So, how should you judge a speaker`s sound to determine if it`s doing its job correctly? What should you listen for? To start with, play a wide variety of different kinds of music with which you`re familiar. Listen for a natural, balanced tonal presentation. Your general first impression should be that the sound is wide range, with strong bass, clear vocals and instruments, and a sparkling treble region. It should have a general feeling of sounding natural, as music does in real life, and no one tonal area

2022-05-25 Tweeters and Woofers If you observe carefully, you may notice that in most loudspeakers, particularly as they get larger than little portable boom boxes, you can see more than one speaker driver-usually a smaller diameter one atop a larger one. These speakers have two sizes of speaker driver: tweeters above and woofers below There are several reasons why speakers use multiple drivers in different sizes. While it is true that a single driver can cover almost all the audible spectrum by itself, there are a number of limitations it runs up against. If the driver is small it can't move much air and will struggle to generate bass at a useful level.

2022-05-23 How do speakers work? Instructions: Ever wondered how speakers work? This is what you need to know. Although there have been significant advances in both speaker design and manufacture, the fundamentals of speaker driver technology haven`t changed in close to 100 years: Edward Kellogg and Chester Rice`s 1925 dynamic driver is still the basis of practically every loudspeaker on the market today, from the one in your phone to those in your home theatre system. But how do speakers work? Let's start with the basics. How speakers work: the basics
