Embodiment
Below in conjunction with accompanying drawing 1 to Fig. 3 and embodiment, the utility model is further described.
Embodiment: a kind of sound equipment, comprise housing 1, cave in and form an accommodation space 7 in the lower end of the trailing flank of housing 1, in this accommodation space 7, circuit board 8 is installed, described circuit board 8 comprises voicefrequency circuit and webtv box circuit, the audio digital signals output of webtv box circuit is connected with the audio digital signals input of voicefrequency circuit, in described housing 1, is provided with whole-tone loudspeaker 5, and whole-tone loudspeaker 5 is connected with the analog signal output of voicefrequency circuit.
The utility model simply forms the webtv box circuit of existing webtv box and voicefrequency circuit to a circuit board, audio digital signals input during voicefrequency circuit on former sound equipment is directly connected with the digital audio output of TV box simultaneously, reduced holding wire, reduced costs.Reduce usage space simultaneously, be convenient to deposit.
Certainly, the another kind as the technical program is deformed into:
A kind of sound equipment, comprise housing 1, cave in and form an accommodation space 7 in the lower end of the trailing flank of housing 1, in this accommodation space 7, circuit board 8 is installed, described circuit board 8 comprises audio board and webtv box circuit board, audio board and webtv box circuit board are respectively equipped with board to board connector, pass through board to board connector, audio board is connected with webtv box circuit board, simultaneously, the audio digital signals output of webtv box circuit is connected with the audio digital signals input of voicefrequency circuit, in described housing 1, be provided with whole-tone loudspeaker 5, whole-tone loudspeaker 5 is connected with the analog signal output of voicefrequency circuit.
Also can directly utilize existing audio board and webtv box circuit board, only need to two circuit boards 8 be connected as one at its interface upper mounting plate to connector for substrate, simultaneously corresponding interface connects.
Further, described accommodation space 7 is provided with back shroud 2, back shroud 2 and housing 1 snapping, and back shroud 2 is provided with a plurality of louvres 21.
Due to webtv box circuit and voicefrequency circuit are integrated into a circuit board 8, its power consumption is larger, so caloric value is also larger, therefore on back shroud 2, is provided with louvre 21.
