Problems solved by technology

[0002] For the current multimedia equipment, mainly including audio and video equipment, it must be equipped with a display screen and a speaker. Since the display screen cannot block the speaker, the speaker needs to be arranged on the side of the display. Therefore, the size of the current audio and video playback equipment is difficult to reduce. ; Especially for some portable devices, if it is necessary to ensure a large adjustable volume, the volume of the speaker is very considerable. After making it juxtaposed with the display screen, the overall volume of the device will be very large and difficult to carry

Embodiment 2

[0019] exist image 3 In the shown second embodiment, different from the first embodiment, two voice coils 4, 4' are fixed behind the display screen 5, one of which is fixed behind the center of the display screen 5, and the other is fixed at the rear of the display screen 5. The non-central position of 5, each voice coil matches one of the permanent magnet seats 3, 3'; the audio output module on the circuit board 2 is equipped with a frequency divider; the voice coil 4 fixed on the rear of the center of the display screen 5 The other voice coil 4' is electrically coupled to the output port of the frequency divider in the low frequency range, and the other voice coil 4' is electrically coupled to the output port of the frequency divider in the high frequency range. According to the second embodiment, the low-frequency part in the audio is in the central part of the display screen, and the display screen is pushed in a large area to display the low-frequency signal superiorly, ...

Abstract

The invention provides a multimedia display which comprises a housing. A circuit board and a permanent magnetic seat are arranged inside the housing; the permanent magnetic seat is matched with a voice coil capable of vibrating front and back relative to the permanent magnetic seat under the action of an electromagnet force; the voice coil and a display screen are mutually fixed, so that the voice coil pushes the display screen to vibrate front and back when vibrating front and back; the display screen comprises a horn-shaped diaphragm formed by OLEDs; the periphery of the display screen is connected to the housing by a rubber ring; and the voice coil and the display screen are respectively and electrically coupled to an audio output module and a video output module on the circuit board. The multimedia display has a simple structure and a small volume, and can provide a sufficiently high volume.

Description

technical field [0001] The present invention relates to the field of multimedia equipment, in particular, to a multimedia display. Background technique [0002] For the current multimedia equipment, mainly including audio and video equipment, it must be equipped with a display screen and a speaker. Since the display screen cannot block the speaker, the speaker needs to be arranged on the side of the display. Therefore, the volume of the current audio and video playback equipment is difficult to reduce. ; Especially for some portable devices, if a larger adjustable volume needs to be ensured, the volume of the loudspeaker is very considerable. After it is juxtaposed with the display screen, the overall volume of the device will be very large and difficult to carry. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a multimedia display, which has a simple structure, a small volume, and can provide a suffic...
