With the market change, the era of wired headphones has been transformed into TWS headphones, and its related industrial chain has also ushered in a new opportunity for transformation towards the era of full automation.
Lianzhonglian (Dongguan) Technology Co., Ltd. (hereinafter referred to as: Lianzhonglian), is a deeply rooted in the headphone speaker research and development, production, sales, service as one of the advanced high-quality technology enterprises; has a number of utility model technology patents, the workshop line using high-precision automated line production, synchronous can provide tailor-made various types of headphone structure design solution services according to customer needs; long-term ingenuity quality, intensive cultivation service has won the high trust of major international brands.
At present, the main products of Lianzhonglian are: external magnetic high-quality speakers, internal magnetic high-quality speakers, and internal welded high-quality speakers. External magnetic high-quality speakers have φ6.0mm, φ7.5mm, φ10mm, φ11.5mm four sizes, of which φ7.5mm high-quality speakers can be professionally tailored for TWS headphones, at the same time, can also be used for hearing aids / monitoring headphones; internal magnetic high-quality speakers have φ10mm thin, φ13mm thin, φ24mm three sizes; welded high-quality speakers have φ11mm, φ13mm two sizes.
1. External magnetic high-quality speaker
Lianzhong lian φ6.0mm, φ7.5mm, φ10mm, φ11.5mm four sizes of high-quality speakers, using super magnetic structure to drive super magnetic structure, to achieve super heavy bass and ultra-high frequency wide extension to 100KHz; drive more balanced and stable exclusive air wiring patent technology, transient response is more rapid; sound quality in line with Hi-Res standards, restore rich sound realism, enjoy super sense of presence.
In addition, the φ7.5mm hearing aid/monitor headphone speaker of Lianzhonglian adopts the patented technology of driving more balanced exclusive air wiring + external magnetic structure. It can provide an exclusive listening assistant headphone cavity structure scheme, which can greatly reduce the microphone acoustic problem, and realize the miniaturization of the headphones on the premise of successfully maintaining a high-performance small caliber, and effectively eliminate the fatigue of long-term use by the user.
2. Internal magnetic high-quality speaker
Lianzhong lian φ10mm, φ13mm two thin internal magnetic high-quality speakers, suitable for TWS headphone speakers, ultra-thin size design, can save more internal space. It has the characteristics of small size, light weight, low distortion, restoration of rich sound realism, and enjoyment of super presence.
The φ24mm internal magnetic high-quality speaker adopts the patented technology of driving more balanced exclusive aerial wiring, and the transient response is faster; it can provide professional human ear acoustics supporting headphone structure design to achieve the industry's lightest headphones; and can provide an exclusive patented speaker sleeve structure scheme that is more suitable for human ear wearability to achieve the super heavy bass effect of the headphones.
3. Welded high-quality speaker
These two products use the welding process design ultra-thin size, saving more internal space of TWS headphones; the use of unique aerial wiring technology to make the horn unit drive system more stable, the three-frequency sensitivity more balanced; high-fidelity to meet the Hi-Res standard, the wide frequency range to achieve from ultra-low frequency 10Hz - ultra-high frequency 100Hz regeneration capabilities; unique sound effect technology to make the sound restoration more natural and realistic.
Lianzhonglian will participate in the [2022 (Spring) Asian Smart Wear Conference], booth number: B99. Welcome industry partners to come to the conference site and lianzhonglian to further exchange and share market information.
