Abstract

L'invention concerne un procédé de transmission de données audio, celui-ci étant appliqué au domaine technique des communications à courte distance et pouvant améliorer la probabilité qu'une première oreillette et qu'une seconde oreillette d'un écouteur TWS reçoivent correctement un paquet de données audio. La solution spécifique comprend : une première oreillette servant d'oreillette primaire établissant une première connexion Bluetooth avec un dispositif électronique, et la première oreillette établissant une seconde connexion Bluetooth avec la seconde oreillette servant d'oreillette secondaire. La seconde oreillette peut recevoir un paramètre de connexion, envoyé par la première oreillette au moyen de la seconde connexion Bluetooth, de la première connexion Bluetooth. Par conséquent, lorsque le dispositif électronique envoie un paquet de données audio à la première oreillette au moyen de la première connexion Bluetooth, le paquet de données audio envoyé par le dispositif électronique peut être acquis en fonction du paramètre de connexion. Lorsque la différence entre les qualités des signaux de l'oreillette primaire et de l'oreillette secondaire recevant le paquet de données audio est supérieure à une valeur de seuil de différence prédéfinie, la seconde oreillette arrête l'acquisition du paquet de données audio envoyé par le dispositif électronique, et l'oreillette primaire de la première oreillette et de la seconde oreillette transfère le paquet de données audio reçu du dispositif électronique à l'oreillette secondaire.
