A control logic means preferably for a receiver comprising a jitter buffer means adapted to receive and buffer incoming frames or packets and to extract data frames from the received packets, a decoder connected to the jitter buffer means adapted to decode the extracted data frames, and a time scaling means connected to the decoder adapted to play out decoded speech frames adaptively. The control logic means comprises knowledge of whether a state recovery function is available and is adapted to retrieve at least one parameter from at least one of the jitter buffer means, the time scaling means, and the decoder, to adaptively control at least one of an initial buffering time of said jitter buffer means, the knowledge of the availability of the state recovery function, and a time scaling amount of said time scaling means from the time scaling means or the decoder.

The embodiment of the invention relates to a control method and a control device. The method comprises the steps of acquiring audio information of current environmental noise, acquiring intensity value of current environmental noise according to current audio information, amplifying or lessening collected local call audio information according to intensity value of current environmental noise, and sending the amplified or lessened local call audio information.

The invention discloses an earphone for communication. The earphone comprises a rubber sleeve, rubber connecting rods are connected to the inner walls of the two sides of the rubber sleeve in a sliding manner; connecting blocks are fixed to the ends, away from the rubber sleeves, of the two rubber connecting rods through screws. A first earphone shell and a second earphone shell are fixed to the outer walls of the opposite sides of the two connecting blocks through screws correspondingly. Grooves are formed in the outer walls of the opposite sides of the first earphone shell and the second earphone shell, loudspeakers are fixed to the inner walls of the grooves through screws, and connecting columns are fixed to the inner walls of the sides, away from the first earphone shell, of the second earphone shell through screws. The fabric is good in air permeability;, Compared with the prior art, the earphone has the advantages that the wearing comfort is obviously improved, the influence onthe normal work of the earphone due to the fact that sweat permeates into the earphone shell in the wearing process is avoided, the external sound interference is isolated, the listening quality of the earphone is improved, components in the earphone are prevented from being burnt out after long-time working, and the service life of the earphone is obviously prolonged.
