Hi @Ra36, let me see if I can be of any help here.
As @uliwooly mentioned, your question has been translated to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
The model number you mentioned is a for a speaker made by another department here at Sony called Sony Electronics. For the best assistance possible I suggest that you get in contact with their support forum that you can find here.
Feel free to return if you have any questions regarding a Xperia phone or tablet!
