Description

Wireless television sound box with broadcasting pair of multimode and language enhancement functions Technical Field The utility model relates to a television sound box, in particular to a wireless television sound box with a pair of broadcasting multimode and language enhancement functions. Background In order to improve the radio experience of users, the wireless television sound box is increasingly widely applied. The current wireless television loudspeaker box is generally composed of a transmitter and a receiver loudspeaker box, wherein the transmitter is connected with a television to acquire audio signals, and the receiver loudspeaker box is provided with a power amplifier module to broadcast the audio signals in a sound mode. In order to save the audio line and facilitate the user to locally perform the television sound box, the audio signal is transmitted between the transmitter and the receiver sound box by wireless at present, however, the transmission between the transmitter and the receiver sound box by the scheme of wireless transmission at present needs a long time, which can lead to a long delay between the television playing and the sound hearing of the user and can affect the viewing experience of the user. In addition, the wireless television loudspeaker box is generally in a form that one transmitter corresponds to one receiver loudspeaker box at present, and when the wireless television loudspeaker box is applied to environments of a plurality of receiver loudspeaker boxes, the problem of transmitter resource waste exists. Therefore, how to design a wireless television sound box with a pair of broadcasting multimode and language enhancement functions, which can realize the communication between a transmitter and a plurality of receiver sound boxes and headphones, is a technical problem to be solved in the industry. Disclosure of utility model Aiming at the problem of resource waste of a transmitter in a wireless television sound box in the prior art, the utility model provides the wireless television sound box with a pair of broadcasting multimode and language enhancement functions. The technical scheme of the utility model is that the wireless television loudspeaker box with a pair of broadcasting multimode and language enhancement functions is provided, and comprises a transmitter connected with a television, and a plurality of receiver loudspeaker boxes or headphones capable of wirelessly communicating with the transmitter; The transmitter, receiver speaker, and earphone all have an audio chip with a BT Modem for performing 2.4G Modem processing, and BTBaseband for performing 2.4GBaseband processing; the receiver sound box is also provided with a power amplification module, and the power amplification module is connected to the loudspeaker and/or the earphone and can transmit the audio signals processed by the audio chip in the receiver sound box to the loudspeaker and/or the earphone. Further, the transmitter is further provided with an HDMI input unit, an optical fiber input unit, a first 3.5mm audio line insertion detection unit, a first connection key, a power indicator and a power interface, wherein the HDMI input unit, the optical fiber input unit, the first 3.5mm audio line insertion detection unit, the first connection key, the power indicator and the power interface are connected with the audio chip.
