It says - BLUETOOTH SUPER BASS PORTABLE SPEAKER. This wireless speaker has a good deign and enough heavy weight for staying on a table and has worked well for about three years under very light use (seldom used). The sound quality is good. But it reached the battery life and no re-charging can be made though it announces "Please charge". I liked it but decided to open it.
When I purchased this it is bare has no box usually showing technical specifications. The operating side (bottom) shows a very brief spec. It says
Working Voltage 3.7V
Frequency Range: 60Hz -18KHz
Charging Voltage: 5V
Power: 3W
Inside:
1) 28 pin IC: ACCFCV56.1-07ABT
I cannot identify this on the internet. Logo seems <JL> or <JC> (*).
2) RDA5876: I found the spec of RDA5876P - SINGLE CHIP FOR BLUETOOTH & FM RADIO TUNER.
3) (MD BX1511) MD25D80S1G: I found the following on the China internet.
SPI NOR: MD25D80SIG 8Mbit 1MB SOP8
SPI is not the brand name but stands for Serial Peripheral Interface.
4) LTK9902B SOP8 - Audio Amp 3W (same as the previous report ‐China made Wireless Speakers - 1)
I plan to change the battery as I have some stock.
--------
<JL> or <JC> (*)
After re-checking I found <JieLi Ttechnology> use this logo <JL>.

However, I am not sure right now if the above 28 pin IC: ACCFCV56.1-07ABT belongs to this company or not.

ReplyDeleteWith the consistent inflow of sightseers, it is no enormous thing to have the option to snag a Sands Shipped SSD hard drive price in pakistan. Be that as it may, when you are getting a real item conveyed to your doorstep, particularly assuming it is a worldwide one, there are such countless interesting points. You don't simply need to contemplate the SD delivering charges when you are requesting through an online store - there are such countless different things that you need to think about. These incorporate the way that you would need to pay for the delivery costs also, which could wind up being very exorbitant, also every one of the additional costs that you need to bear like traditions, obligations and the wide range of various problems that show up with worldwide conveyances.
ReplyDeleteI Like to add one more important thing here, The Wireless Audio Device Market is expected to grow from US$ 60.74 billion in 2020 to US$ 113 billion by 2027 at a CAGR of 19.72% from 2020 to 2027.
