Abstract: A bass-reflex enclosure including a enclosure housing, a speaker, and a bass reflection tube is provided. The bass reflection tube is disposed on the front case or the rear case. The bass reflection tube has an inner opening and an outer opening. The inner opening is located in the enclosure housing, and the outer opening is located outside the enclosure housing. The bass reflection tube includes a tube body arranged at the inner side of the front case or the rear case and a cover plate arranged at the inner side or the outer side of the tube body. The bass-reflex enclosure provided by the present disclosure can not only improve the bass effect well through the set bass reflection tube under a smaller volume, but also has a simple structure and easy installation, and has a good application prospect.

Abstract: A soundbar is disclosed. The soundbar includes a circuit board module, a loudspeaker and a sound cavity housing. The loudspeaker is installed on the sound cavity housing. The sound cavity housing includes a front housing and a rear housing. A rear lower part of the rear housing is provided with a first groove structure. The circuit board module includes a circuit board, and the circuit board includes an audio interface unit, an audio processing unit and a power amplification unit connected sequentially. An output end of the power amplification unit is connected with an input end of the loudspeaker, and the audio interface unit includes a wired audio interface circuit and/or a wireless audio interface circuit.

Abstract: In the context of a wireless communication network, relay-based communication is provided. In particular, a relay node (100) comprises a receiver (110) configured to receive a signal representative of a message transmitted from an originating node and intended for a destination node, wherein a transmission from an interference source causes interference in the received first signal. The relay node (100) also comprises an interference detector (130) configured to detect interference from the interference source in the received signal and which part of the message that is affected by the interference, called the interfered part of the message, and a forwarding unit (120) configured to perform a partial retransmission based on the interfered part of the message to the destination node.
