A Bluetooth speaker with a type-C interface

technical field

The utility model belongs to the technical field of audio, in particular to a bluetooth audio with a type-C interface.

Background technique

For people living in cities, regular outdoor exercise is a very healthy way, such as running, climbing, walking and so on. However, many friends like to listen to music while exercising outdoors. With the company of music, they will be more energetic during exercise and add some entertainment atmosphere. When listening to music, a portable Bluetooth speaker is indispensable. Compared with wired speakers, Bluetooth speakers are free from the shackles of wires and are more convenient to use.

However, there are many Bluetooth speakers on the market at present, and there are various types. With the subdivision of the market and the increase of competition, major manufacturers have launched portable Bluetooth speakers for outdoor sports enthusiasts. These Bluetooth speakers have both AUXin interface with 3.5mm aperture and Micro-USB interface. There are many types, and there are many types of connectors and wires that need to be adapted. It is very inconvenient to carry, and the Micro-USB is easy to insert backwards, which is inconvenient to use.

USB Type-C is the next-generation USB connector, which has faster transmission speed (up to 10Gbps) and more powerful power transmission (up to 100W). The biggest feature of Type-C double-sided pluggable interface is that it supports dual USB interface It can be inserted from both sides, which formally solves the worldwide problem of "USB can never be plugged in correctly". However, there are currently no Bluetooth speakers on the market that use the USB Type-C interface.
