Bluetooth speakers refer to audio equipment with built-in Bluetooth chips, which use Bluetooth connections instead of traditional wire connections. By connecting with Bluetooth playback devices such as mobile phones, tablets, and notebooks, they achieve the purpose of convenience and speed.
Bluetooth speakers are mainly portable speakers, and their appearance is generally small and portable. Bluetooth speaker technology has gradually been valued and accepted by consumers due to its convenience. Most common Bluetooth speakers on the market are mono speakers (single speaker unit). At the same time, some multi-channel speakers (two or more speaker units) with excellent sound quality have emerged.
Bluetooth speaker is to apply Bluetooth technology to traditional digital and multimedia speakers, so that users can listen to music freely in various ways without being entangled by annoying wires. Since the advent of Bluetooth speakers, with the development of smart terminals, they have received widespread attention from users such as mobile phones and tablets.
In 2012, with the rapid development of bluetooth smartphones and tablet computers, their performance and screens have amazed consumers. Affected by their size, there is no good solution for speakers alone. Hearing is also one of the most important perceptions of human beings, and consumers are increasingly demanding this part. Bluetooth speakers have taken advantage of the trend. The portable way, wireless transmission, and stylish appearance are strongly loved by consumers.
Unlike other wireless speakers, Bluetooth speakers have their own unique features:
1. Wide range of applications
Bluetooth technical specifications are unified globally, mobile phones, PDAs, wireless headsets, notebook computers, automobiles, medical equipment, computer peripherals and many other devices, as long as you have a Bluetooth adapter, you can easily connect to Bluetooth devices for data transmission or voice communication, widely popularized , good compatibility.
2. Easy to operate
Bluetooth technology is an instant technology, it does not require a fixed infrastructure, and it is easy to install and set up. It can be connected without cables.
3. Faster transmission speed
Compared with other methods such as infrared, the Bluetooth transmission protocol has obvious advantages in speed. The theoretical maximum speed of Bluetooth 4.0 reaches 24Mbps, and a faster speed can ensure higher sound quality, so that it has enough capacity to carry a higher bit rate. music.
4. Moderate transmission distance
The transmission distance of Bluetooth is generally within 10 meters, which is exactly the size of a room, and can transmit data across walls, which is very suitable for home use.
Although it has many advantages, because the Bluetooth transmission protocol, like other 2.4G devices, shares the signals of this frequency band, it will inevitably lead to mutual signal interference. In addition, the Bluetooth protocol is not a free technology. Any manufacturer using this technology must pay a patent fee to the organization, and this part of the fee will also be reflected in the cost. In 2012, the price of Bluetooth audio equipment is still high. on ordinary products.
Mainly according to the pronunciation unit and use can be divided into several types.
The first category: mini portable with single speaker
In terms of pronunciation units, the mini portable Bluetooth speakers mainly include a speaker, a speaker + a bass radiator, a speaker + an inverter hole, and a speaker diaphragm integrated type. In terms of function, it is mainly divided into ordinary single-tube mini bluetooth speakers and outdoor mini bluetooth speakers.
Ordinary monocular mini bluetooth speaker
In the initial stage of Bluetooth speakers, this simple single-tube Bluetooth speaker is the most prosperous. Due to the simple structure and process, no special technical support is required, it has attracted a large number of manufacturers to produce, and because the price is cheap, it is very popular among people who are new to Bluetooth speakers, and there are countless such speakers on the market for a while. It has made a lot of contribution to people's understanding and familiarity with Bluetooth speakers. However, due to the constraints of its own conditions such as too small sound cavity, serious product homogeneity, and low price, it is difficult to make a breakthrough in the sound quality of the speaker, and the battery life is relatively short, mostly between 2 and 3 hours, resulting in this The use of speakers is very limited, and most of them can only be used in fixed places. Most of its users have no requirements for sound quality, so ordinary single-tube Bluetooth speakers with low prices are easy for the public to buy.
Outdoor Monocular Mini Bluetooth Speaker
Since ordinary mini bluetooth speakers are difficult to meet the requirements of the outdoor environment, outdoor mini bluetooth speakers came into being. It is wireless, portable, and can be used at home and outdoors. It can meet the basic waterproof and drop-proof requirements, and can meet simple outdoor sports. However, due to the limitation of its small size, its sound quality cannot make a major breakthrough. There have been breakthroughs in portability and waterproof and drop resistance. In terms of battery life, the battery life is generally 3-5 hours and can only be used for short-term outdoor activities. As a transitional product of outdoor Bluetooth speakers, its price is relatively cheap. The main advantages of this type of speakers are small, portable, and easy to carry, but the other side of the small size is the disadvantages of average sound quality, poor bass, and short battery life.
The second category: the perfect combination of sound quality and portability of dual speakers
In terms of pronunciation units, this Bluetooth speaker mainly includes two speakers, two speakers + one diaphragm, two speakers + inverter hole, two speakers + two diaphragms, etc. In terms of function, it is mainly divided into mini household Bluetooth speakers and outdoor sports Bluetooth speakers.
Mini household bluetooth speaker
This type of speaker has been greatly improved in sound quality and can basically meet the needs of most people, unless you have very high and professional requirements for sound quality. Its sound quality is good. Small and portable, basically the size of a palm, it is suitable for home placement. It has various shapes and product designs. It is a good Bluetooth speaker. However, since it is not specially designed for outdoor sports, the grip of the product is average, and there is no waterproof and anti-drop function, so it is mainly used indoors.
Outdoor sports bluetooth speaker
Outdoor sports models are upstarts in the Bluetooth speaker market. It combines various advantages of the previous speakers. The speaker has a good grip and is easy to carry. It can meet both home use and long-term outdoor use. Due to the relatively high requirements for the use of professional technology and materials, generally only some big brand merchants design and produce, the workmanship is more meticulous, the materials are more exquisite, and there is certain technical support. Its sound quality can reach a relatively high level, better than ordinary Bluetooth speakers, and can satisfy most users. Due to the need to meet some extreme outdoor environments, this type of product has been specially designed in materials, and generally has a strong three-proof function, and its battery life is long-lasting, generally between 10-20 hours. The price ranges from 400 to 1500 yuan. This kind of speaker that combines portability and sound quality is very good in practicality and applicability, and will become the mainstream of the Bluetooth speaker market in the future.
The third category: large household type with multiple speakers
Multi-speaker large home bluetooth speaker
Multi-speaker large-scale home Bluetooth speakers are mainly good at sound quality, and the price is relatively expensive. Based on high-demand technical support, it is generally designed and produced for big brand merchants. This kind of Bluetooth speaker pursues an unlimited breakthrough in sound quality, so it is aimed at users who have higher requirements for sound quality, and it is relatively small because of its high price.
