In the second half of 2018, "TWS Bluetooth speakers" quietly emerged in the market. Today, I will talk about TWS Bluetooth speakers. Speaking of TWS Bluetooth speakers, we have to start with TWS, TWS: True Wireless Stereo (TWS full name True Wireless Stereo) originated from Bluetooth® Bluetooth®, Bluetooth technology is a wireless technology standard that can be used for fixed devices, mobile devices and buildings Short-distance data exchange between personal area networks (using UHF radio waves in the 2.4-2.485 GHz ISM band). Bluetooth technology was originally created by telecommunications giant Ericsson in 1994 as an alternative to RS232 data lines. Bluetooth can connect multiple devices, overcoming the problem of data synchronization.
Today's Bluetooth is managed by the Bluetooth Special Interest Group (Bluetooth Special Interest Group, SIG). The initiators of the Bluetooth SIG are Agere, Ericsson, IBM, Intel, Microsoft, Motorola, Nokia and Toshiba. The Bluetooth Technology Alliance has more than 25,000 member companies worldwide, which are distributed in multiple fields such as telecommunications, computers, networks, and consumer electronics. The IEEE lists Bluetooth technology as IEEE 802.15.1, but the standard is no longer maintained today. The Bluetooth Technology Alliance is responsible for overseeing the development of Bluetooth specifications, managing certification projects, and safeguarding trademark rights. The manufacturer's equipment must comply with the standards of the Bluetooth Technology Alliance in order to enter the market as a "Bluetooth Device". Bluetooth technology has a patented network that can be distributed to standard-compliant devices.
In 2017, True Wireless Stereo-TWS began to emerge. It was first applied to TWS Bluetooth headsets. The same Bluetooth technology was later applied to TWS Bluetooth speakers. The principle is the same as TWS headsets. Two speakers that support TWS Bluetooth pass through the Bluetooth chip. Link up and connect the pair of speakers through a mobile phone to achieve true Bluetooth left and right channel wireless separation. The main speaker returns to the single stereo without delay and the sound quality is good. TWS Bluetooth speakers originated from Bluetooth 4.2. Most of the TWS chips on the market are based on Bluetooth 4.2 and above. The latest Bluetooth 5.0 technology has a wider frequency band than 4.2. You can listen to SQ while enjoying music. HQ high-quality music. More manufacturers have applied DSP technology based on Bluetooth 5.0 in audio decoding. As a result, Bluetooth technology has reached an unprecedented height in wireless music hearing.
Bluetooth 5.0 technology, there are many domestic manufacturers, of course, the technology is also uneven, the price is also different, overseas Bluetooth original manufacturers represented: Qualcomm (Boadcom), CSR, REALTEK, TI, ST, TOSHIBA, Airoha; Actions Zhuhai and Broadcom Shanghai are the first-line representatives. Chips such as Zhuorong, Torch, Hengxuan, etc. are mainly used by manufacturers in the ranks of low-end products, that is, products that run in volume, and the price is astonishing dozens of yuan. According to many products measured, they can only be called TWS entry-level products. , The experience effect is poor, after all, electronic products are worth what they are worth.
Tested on Goodlark GT201 TWS Bluetooth speaker, the chip uses the "torch force" Bluetooth 5.0 chip, which is known as the originator of the domestic audio industry, and the tuned dual 18-core full-frequency speakers and dual-vibration diaphragms make the low-frequency dive deeper and richer Flexibility to meet the user's desire for low frequencies; matched with Braun Acoustics' own omnidirectional noise reduction microphone, it has an excellent experience during hands-free calls. In terms of acoustic experience, its sound quality and sound effects are comparable to top brands at home and abroad.
The author has continued to pay attention to TWS products and technology and market dynamics since 2017. After the normalized TWS Bluetooth headset, the many TWS products derived will also lead this category to a higher point, and TWS Bluetooth speakers will also become Bluetooth speakers. Mainstream products of this category. With the update and application of new products and technologies, Bluetooth speakers will not only be satisfied with daily audio and video use in the next few years (perhaps 2-3 years), the AI field will be the first to fully penetrate, accompanied by semi-intelligence and intelligence. With the development of globalization, TWS smart Bluetooth speakers will be the next outlet. At present, the products that can mass-produce TWS technology into Bluetooth speakers are not very rich. I believe that more TWS Bluetooth speakers will appear on the market after the second half of 2019. To do well in speaker-level applications, many technical problems need to be solved.
