Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0019] Each Blu-ray player has a maximum and minimum output volume, that is, the volume control range, and the common value is 0-100.

[0020] The volume control method of the Blu-ray player of the present invention involves four volumes: maximum volume (max volume), output volume (volume), earphone volume (earphones volume) and power on volume (power on volume). The output volume refers to the volume output by the Blu-ray player during normal playback, the earphone volume refers to the output volume when the earphone is plugged in, and the power-on volume refers to ...

Abstract

The invention discloses a blue-ray player and a volume control method and device of the blue-ray player. The volume of the blue-ray player includes output volume, earphone volume and starting volume, the volume can be adjusted conveniently by a user according to needs, the player is more human-friendly, and the volume adjustment functions are enriched. Maximum volume is set as an upper limit, and the output volume and the starting volume are controlled not to exceed the maximum volume to avoid damaging a loudspeaker and other power amplification devices of the user. The maximum volume can be set by the user, and the front-stage functions of the blue-ray player are more complete.

Description

technical field [0001] The invention relates to the technical field of electronic players, in particular to a Blu-ray player and its volume control method and device. Background technique [0002] The current Blu-ray players all follow the volume control method of traditional playback tools such as DVD, MP3, MP4, and TV. After starting up, the user controls the volume through the tuning button, and the volume control area is from 0 to 100 (some players are 10) . This method is an extensive volume control method, which only meets the basic needs of users, and there are many more practical and specific needs that are not taken care of. [0003] Nowadays, the audio and video decoding function of the Blu-ray player is very complete, and many users will directly use it as a preamplifier to work with the loudspeaker. However, most amplifiers lack the volume adjustment function, so there will be a serious situation that the volume output by the Blu-ray player is too loud and hurt...
