Update #29 Product development progress.
Thank you for your patience and waiting! We can not do this without the support from all of you.
We understand you have been waiting patiently and we very much appreciate that. Meanwhile, our team has been working very hard to enable all the parts, hardware and software, that will make Vinci 2.0 a successful product and also meet our quality standards. To do this, we know we must be very honest about our progress and our backers deserve to know all the work that has been put into this.
Hardware - mechanical:
Hardware design is still our main challenge towards mass production. As we mentioned last time, we have incorporated new OLED structural design, the joint design at each corner of the pentagon, and the new tooling designs. Still, we are unhappy with the results. We do not want to ship a product that does not meet our quality standards.
The major challenge comes from the hybrid design that incorporates a stainless steel body and the silicon rubber encapsulation. Working with these two materials has proved to be much more challenging than we had planned. A new silicon rubber design has been completed to deal with incomplete encapsulation and cracking over the reliability tests (temperature cycling).
With all these changes, we had to overhaul the assembly procedure. All parts are now attached securely onto the backbone supported stainless steel frame, followed by the final encapsulation of silicon rubber.
Hardware - electronics:
We have been battling with the power consumption associated with voice wakeup. Our team decided to add a new voice wakeup chip dedicated for wakeup function. This work has been completed.
Old: voice wakeup is software simulated. Doing so requires the OS to be actively listening to user voice command.
New: voice wakeup is now supported by dedicated hardware. Improved power consumption by 20%.
A new gesture sensor is introduced. The old one will interfere with the audio signals and introduces background noises that compromise user experience.
We also re-designed a new set of PCB routing and introduced new metal shielding to prevent electromagnetic interference.
-Improved GPS sensor location accuracy.
Google Assistant Google Assistant has been integrated and been an integral part of Vinci 2.0’s voice interaction. Users will experience a seamless transition between Vinci’s AI assistant and Google assistant. Features included so far:
- Integrated Spotify
- Date and Time
- Schedule - Search
- Easter eggs
(the prototype is tested in our hardware lab in China office with VPN on, so Google Assistant's responses are a bit slow, but in normal conditions, it works much faster)
You will experience Spotify Music and Many of the GA features within one login (Spotify login required). For Amazon Alexa, you will need a separate login to enable the Alexa feature (Alexa login required).
Strava support has been completed and tested. You can now sync your activity data from headphone to your Strava account (login required).
System Optimization: Power consumption Improve data synchronization performance (Both for Android SPP and iPhone BLE)
Audio: updates on Adaptive Noise Filtering We have achieved another milestone in Adaptive Noise Filtering.
- [Competed] basic research about noise-pattern-recognition with Neural Network in 5 different noise-scenario;
- [Completed] initial offline prototype demo
- [Completed] the V1.0 released
- [On-going] integration and relevant validation of V2.0 Release on Vinci Headphone’s OS
- [Planned] fine tune and improvement of release for best ASR performance on final Vinci 2.0 device
The above figure shows our adaptive noise filtering results.
As a start-up company in a very crowded audio industry, we consider it paramount to aim for the supreme quality product, which we believe all our backers deserve. Therefore, we have decided to continue polishing our hardware and toolings until it meets our quality standards. For this reason, we will need to postpone headphones release date until December 2018. We will do all our best to make sure you receive your products before the Christmas Holiday. We understand this news could be frustrating for some of our backers, but we do appreciate your understanding and patience.
