Embodiment Construction
[0022] Such as figure 1 or figure 2 As shown, there is an L-shaped hanging ear 13 on both sides of the player chassis 3. One end of the L-shaped hanging ear 13 is fixed to the side of the chassis 3, and the other end stretches out from the left or right end, and on the hanging ear that protrudes from the left or right end. There are two installation holes. The installation holes are the same up and down as the installation holes of the standard rack 1, and the size is the same. Use slotted or Phillips screws to fix the player chassis 3 fixed with the hanging ears 13 to the standard rack 1. .
[0023] The playback controller 9 on the panel 5 has control buttons, SD / MS / MIC card slot, USB slot, remote controller and power supply, earphone jack. The height of the player is 1U or 2U or 3U. For a player with a height of 1U, the height of the mounting ears is 44.45 mm, and each mounting ear has at least 2 mounting holes, and the hole distance is the same as that of the standard p...

Abstract
The invention discloses a design method for a machine frame type digital player. Installation holes are respectively arranged on the left side and the right side of a case for installing suspension loops, and two installation holes arranged on the suspension loops are used for achieving fixed connection of the player base and a standard machine frame. A panel loudspeaker, a front panel loudspeaker and a lateral panel loudspeaker are arranged on the case, a play controller is arranged in the middle of a case panel, and a control key, a universal serial bus (USB) slot, a secure digital (SD) / memory stick / (MS) / microphone (MIC) card slot, a remote control receiver and an earphone socket are arranged on the play controller. A digital play is suitable for being carried or placed on an operation table, and especially suitable for being arranged on various standard communication pallets and case panels, and can achieve repeated play of audio files in a USB flash disk or a storage card.
Description
technical field [0001] The invention relates to a design method of a rack-type digital player for voice introduction and background music playing in exhibition equipment, demonstration equipment, entrance and exit equipment, and school teaching equipment. technical background [0002] With the development of digital broadcasting technology, audio and video files have been digitally stored. Data storage cards such as hard disks, U disks, and SD / MS / MIC can store a large number of audio and video program files, and these files can be easily played through the controller. The controller can also be miniaturized and miniaturized, making it suitable for installation in various devices. [0003] In various exhibition equipment, demonstration equipment, entrance and exit equipment, and teaching equipment, it is often necessary to accompany the voice introduction or prompt sound, and it is also necessary to repeatedly play the sound. [0004] Traditional digital broadcasting systems...
