Description
Technical field
The utility model relates to TV set-top box technical fields, more specifically to a kind of television set top with speaker
Box.
Background technique
TV set-top box field: the TV of Present Global is all turning digital signal via analog signal, and China has completed
Digital Television Transformation more than 90% plays.Digital TV field, other than the all-in-one machine of minority customization, remaining TV is required to
One DTV STB matches could watch broadcast TV programme.The digital signal of compression can be changed into TV by it
Content, and show on a television set.Signal can come from wire cable, satellite antenna, broadband network and terrestrial broadcasting.
The received content of set-top box other than the image that simulated television can provide, sound is more that digital content can be received, wrap
Include electronic program guides, internet webpage, subtitle etc..
Field of audio: it is other that household sound equipment is broadly divided into three categories, is respectively: home theater sound equipment, Baffle Box of Bluetooth and
Portable earphone.Home theater is mainly matched with television set, in early days for playing VCD, DVD disk film etc., now by
In the less use of space factor and noise pollution factor, only part high-end user customizes private home cinema sound equipment,
It is with high costs.Baffle Box of Bluetooth and Portable earphone are mainly used for consumer electronics, as the micro electrics such as plate, mobile phone, MP3, MP4
The supplement of sub- equipment, matches.
