Abstract
The utility model relates to the communication equipment technology field, and particularly relates to a Bluetooth sound box that is simple in structure and capable of improving transmission sound quality. The Bluetooth sound box comprises a sound box housing, and a circuit board, loudspeakers and a power supply which are installed in the housing, wherein the circuit board is provided with an Apt-X decoder and a Bluetooth transmission module, and Apt-Xy audio compressed data signals of external equipment are received by the Bluetooth transmission module and output by the loudspeakers after passing through the Apt-X decoder. The Apt-X decoder is used for decompressing transmitted audio compressed signals, and an Apt-X audio compression technology is a digital audio compression algorithm. After the Bluetooth sound box is applied to the Bluetooth wireless transmission field, the Bluetooth sound box is low in audio time delay and good in fault tolerance, compression frequency band width is increased, data packets are ensured to be not lost, and compared with traditional Bluetooth transmission, audio quality can be largely improved.
Description
Technical field:
The utility model relates to communication equipment technical field, refer in particular to a kind of simple in structure, can improve transmission tonequality Baffle Box of Bluetooth.
Background technology:
Audio amplifier refers to audio signal to be transformed to a kind of equipment of sound, and popular saying just refer in audio amplifier main frame casing or subwoofer casing and carry power amplifier, and audio signal is amplified after processing and gone out sound by the playback of audio amplifier own.
Traditional audio amplifier is all to adopt wired connection, by adopting wire or data wire to be connected on playback equipment, make its electric joining, realization is transformed to sound by audio signal, if audio amplifier need to be away from playback equipment, need wire or the data wire grown very much, and that this long wire or data wire are easy to is in disorder, and uses very inconvenient.
Occur subsequently a kind of Baffle Box of Bluetooth, it arranges a Bluetooth Receiver in audio amplifier, by this Bluetooth Receiver received audio signal, realizes audio signal is transformed to sound.This Baffle Box of Bluetooth has certain effect, can substantially solve the problem that wired audio amplifier runs into.But because wireless blue tooth technology is widely used in mobile communication, and single Baffle Box of Bluetooth can not meet the demand of social development.First, current Baffle Box of Bluetooth transmission quality is not high, and its transmission loan exists certain bottleneck, and when utilizing bluetooth to carry out audio transmission, audio frequency exists certain delay, causes like this audio signal receiving to have distortion.Secondly, current Baffle Box of Bluetooth is because volume is little, and its inner setting is comparatively simple, and supper bass effect is inadequate.
For above problem, the present invention, through improving, proposes a kind of new Baffle Box of Bluetooth.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of improved Baffle Box of Bluetooth is provided.
In order to solve the problems of the technologies described above, the utility model has adopted following technical proposals: this Baffle Box of Bluetooth comprises: voice box casing and be installed on circuit board, loudspeaker and the power supply in housing, on described circuit board, be provided with Apt-X decoder and Bluetooth transmission module, by Bluetooth transmission module, receive the Apt-Xy audio compression data signal of external equipment, by being exported by loudspeaker after Apt-X decoder.
Furthermore, in technique scheme, described housing comprises upper casing and base, and described upper casing upper end surface is provided with audio amplifier web plate, and described loudspeaker are fixed on the position of corresponding web plate in housing.
Furthermore, in technique scheme, on described base, offer sound hole, in housing, position that should sound hole is provided with to passive loudspeaker.
Furthermore, in technique scheme, described upper casing upper surface is a clinoplain, offers the hole of the loudspeaker for installing in this upper surface.
Furthermore, in technique scheme, described circuit board is provided with key-press input switch, in surface of shell, is provided with the input key group corresponding with this key-press input switch.
Furthermore, in technique scheme, described power supply comprises: rechargeable battery set and charging module, by rechargeable battery set, audio amplifier is powered, and by the interface on charging module, rechargeable battery set is charged.
Furthermore, in technique scheme, the Bluetooth transmission module on described circuit board adopts bluetooth 4.0 standards, and its operating frequency is at 2402MHz-2481MHz.
Furthermore, in technique scheme, on described base, be fixed with a balancing weight.
Adopt after technique scheme, the utility model has following beneficial effect compared with prior art:
1, the utility model adopts Apt-X decoder to carry out decompress(ion) to transmitted audio compression signal, and using Apt-X audio compression techniques is a kind of digital audio compression algorithm.Be applied in behind Bluetooth wireless transmission field, it has audio frequency low delay, zmodem, and bandwidth of its compression frequency band increases, and guarantees that packet can not lose, and with respect to current traditional Bluetooth transmission, its audio quality will be largely increased.
2, the utility model adopts up-to-date Buletooth V4.0 bluetooth module, further improves audio transmission quality.
3, the utility model is provided with passive loudspeaker, can solve like this because audio amplifier cavity is little, and the problem that low sound effect is inadequate, realizes the bass effect of shock more.
