AI intelligence + Internet of Everything is people’s beautiful expectations for the present and future life with the development of science and technology. For example, smart home, smart wear, smart transportation, smart medical and other fields are ushering in a new round of technological upgrades and product upgrades to meet the ever-changing high-quality needs of consumers.
In response to the pain points and market demand for sound quality improvement of smart terminals such as smart watches, smart glasses, smart speakers, smart phones and tablets, and car audio, Goertek Co., Ltd. (hereinafter referred to as “Goertek”) held a meeting in Shenzhen today. At the speaker technology sharing meeting, the upgraded technologies of the two brands of the micro speaker SBS? and the large speaker Cyclone were launched, aiming to help various smart terminals improve the sound quality of the products, so that consumers can hear more clearly and better.
For the smart wearable market: curved diaphragm speakers make products thinner and lighter
With the advancement of technology, wearable devices such as TWS earphones, smart watches, and smart bracelets are rich in functions and highly integrated. After long-term development, the internal structure design and component types of its products have become stable.
In the case of smart watches, most of the designs on the market are square dials, while the designs of circular dials are relatively rare. The reason behind this is that ordinary smart watch speaker solutions cannot fit the inner wall of the dial due to the limitation of shape and structure. place.

The picture shows the disassembly of Samsung Galaxy Watch 3 by iFixit. The speaker unit is circled in red, which is also placed on the side of the fuselage. However, the circular dial and the casing are curved. In order to make full use of the space, the volume of the speaker is correspondingly reduced, which affects the sound quality.
Goertek has launched the world’s first curved diaphragm speaker SBS?-Sandwich in response to the circular dial design of smart watches and the need for thinner and lighter watches. 4 mm, it can be placed vertically against the side of the circular dial, thus saving the space occupied inside the watch, and it can also be designed according to the size of the dial, which is suitable for radians? 42-?46 round dial.
Compared with the conventional watch speaker solution, the SBS?-Sandwich takes up more than half of the internal space of the watch, and the space saved can be used to place larger batteries. The battery life can be increased by 3 days. At the same time, the low frequency of SBS?-Sandwich is fuller and the high frequency is clearer, which makes the sound quality of the watch better. Especially in the case of using multiple watches, the sound quality of the watch can even reach the effect of playing audio on a mobile phone.
In addition to smaller size and better sound quality, the SBS?-Sandwich innovative elastic diaphragm material and waterproof part material are integrally formed to make it reach the industry’s highest waterproof level of 10ATM (100 meters waterproof), helping to realize the use of swimming and even diving with the watch Scenes.
Not only that, the SBS?-Sandwich can also be designed without curvature, which is suitable for square watches and smart glasses. At present, various smart audio glasses are relatively wide in the temple position, because various components are concentrated inside, especially the speaker unit, which needs to be designed close to the ear to reduce sound leakage. Goertek’s SBS?-Sandwich curved diaphragm speaker is very thin, waterproof and sweat-resistant, helping smart audio glasses achieve lightweight design and better sound quality.
Facing the smartphone market: SBS speaker performance upgrade, three-in-one module listening and touch, more cost-effective
Smartphones are the core of the Internet of Everything. In recent years, in addition to stacking hardware performance, smart phone products have also paid more attention to product details. Technologies such as symmetrical dual speakers and linear motors, which are increasingly popular on smartphones, greatly enhance the user’s video and gaming experience.
For brands with higher acoustic performance requirements for mobile phones/tablets, the new generation of SBS?-Rhythm speakers released by Goertek can provide better sound quality.
Goertek has been focusing on the development of micro-electro-acoustics since its establishment. In order to comprehensively improve the performance of mobile phone micro-speakers, Goertek began to deploy SBS (Super Dynamic Balance) speakers in 2016, and continued to innovate and optimize material and structural design. The performance has been continuously upgraded, and has been widely recognized in the industry, and has been used in many mainstream flagship models.
According to Goertek, the new generation of SBS?-Rhythm speakers adopts newly developed diaphragm materials, shells, dome material components and innovative sound-absorbing particle packaging design. The performance under rated power is significantly improved, and the amplitude can reach the highest level in the industry. The vibration is very stable, and Vdmax (maximum push volume, which is the most critical factor in determining speaker performance) can be improved by more than 39%.
After Goertek’s test, compared with the current flagship sound effects, the frequency response of mobile phones using SBS?-Rhythm speakers can be improved by at least 10dB, the bass is fuller and clearer, the dynamic is powerful, and the treble is clear and transparent; the sound details show and achieve stereo sound effects , which is similar to the experience brought to users by smart speakers. Goertek SBS?-Rhythm speakers are confident to raise the sound quality of smart terminals (mobile phones/tablets, etc.) to a whole new level.
On the other hand, the internal space of mobile phones is very expensive and needs to be fully utilized. Based on the trend of multi-sensor fusion in mobile phone products, Goertek also launched the SBS? Magic speaker + receiver + motor three-in-one module, which has both audio and linear vibration functions, and integrates three mobile phone micro speakers, receivers and linear motors. This kind of device, integrated design, the volume is only comparable to the conventional speaker box. Each part of the function can work independently or at the same time, which directly saves the internal space of the mobile phone, improves the assembly efficiency of the mobile phone, and saves the cost for the mobile phone.
According to the calculation of GoerTek’s R&D personnel, the total volume occupied by the top and bottom two Magic modules in the mobile phone is reduced by about 15%. At the same time, because of the blessing of dual speakers and dual motors, the mobile phone can not only have the same sound quality as a high-end mobile phone Excellent sound balance and three-dimensional sense can also achieve the same rich and diverse tactile feedback experience as gaming mobile phones.
