Because Bluetooth technology has low power consumption, strong anti-interference ability, suitable for a variety of communication places and relatively simple integrated circuits, Bluetooth technology has a broad market prospect as a wireless interface technology that replaces cable. Bluetooth technology is becoming the standard configuration in mobile phones, PDAs, MP3 players and computers. One of the mainstream applications of Bluetooth technology is to enjoy the high-quality music and hands-free calls sent by the Bluetooth interface of the above products through Bluetooth headsets. In addition to the advancement of technology itself, it is also closely related to the realization of the cost. The price of Bluetooth headsets on the market is as low as a few hundred, and thousands of dollars, while the price of mobile phones itself is mostly less than a thousand dollars. Relatively high price has led to its market penetration speed and breadth is far lower than mobile phones, the following small series made a Bluetooth headset for your reference.
Disassemble the original headphones
First take the earmuffs down, be careful not to be too violent, moderately strong, don't pull the stitches above...
Then remove the three fixing screws and gently and gently remove the speaker unit. The removed screws can be placed inside the earmuffs, which is not so easy to lose. After half an hour, the total assembly will find fewer screws.
Solder the original audio wire and remove it, leaving the outer casing and speaker section.
Connect the relatively independent left and right parts with the old headphone cable
Since the left and right sides of the original earphone are relatively independent, there is no wire connection, and the production needs to separate the battery and the bluetooth module on the left and right sides, and the left channel output of the Bluetooth module placed on the right side also needs to be connected by the audio cable. On the left, you need to use an old pair of headphones to remove the audio cable.
This is a pair of headphones that have been smashed. Fortunately, the cable is not damaged and can be used.
The reason why the headphone cable removed from the pair of headphones is not used here is because the removed line is too thick, and it is not convenient to route, and the line of the ordinary earphone is relatively thin.
Divide two equal length earphone cords approximately twice the length of the headphone cover.
Disassemble the folding shaft and telescopic part of the earphone. Be careful not to use brute force when disassembling. If it is not open, check whether a screw is removed and try several directions and angles. Otherwise, After you slam, you only have to buy a new headset...
Fully disassembled folding shaft and telescopic section.
Start with the hood part and prepare the wiring.
As shown in the figure, when the headphone cable is pressed into the hood, it suddenly appears that the earphone seems to have been designed with a cable trunking. The earphone cable can be easily pressed in, and even the telescopic and folding shafts have a wire slot. Convenient for this production...
The sound quality of small speakers is also good. It does not have the same large speakers and power as HIFI speakers, and its sound quality cannot compete with large speakers due to physical limitations. But for the vast majority of users who are not golden ears, the use of small speakers with tablets and mobile phones is sufficient to meet their hearing needs.
For Bluetooth speakers, I personally think that when many people buy speakers, the appearance is the first priority and the function is second.
