Description

Combined video and audio equipment suitable for outdoor use

Technical Field

The utility model belongs to the technical field of projection devices and audio-visual equipment, and relates to combined audio-visual equipment suitable for outdoors.

Background

With the improvement of living standard, more and more people are willing to spend more time and energy to perform all activities outdoors so as to enrich living experience. When carrying out outdoor activities, people often carry audio-visual equipment such as outdoor audio amplifier, outdoor mini bluetooth, outdoor DVD and square dance player to satisfy different user demands.

The current outdoor audio-visual equipment such as outdoor DVD and square dance video loudspeaker box is mainly traditional equipment, and the screen is small or does not have the screen, and when in use or only the picture of the small screen can be watched or only the sound can be heard, the experience sense is poor, so that the applicable range of the current equipment is very low. Especially under the condition that many people watch the shadow simultaneously, the effect that this tradition equipment can play is poorer.

In an issued patent, entitled outdoor pull rod speaker laser projector, with publication CN 206728226U, paragraph [0037] in the specification is written in: the outdoor pull rod loudspeaker box laser projector comprises a shell, a telescopic pull rod arranged on the shell and a roller arranged at the bottom of the shell; the outdoor pull rod loudspeaker box laser projector is characterized by further comprising a power module, a main control module, an audio module, a DLP projection module, a signal input module and a heat dissipation module. And specific types of the power module, the main control module, the audio module, the DLP projection module, the signal input module, and the heat dissipation module are shown in the following specific embodiments.

However, the disclosure of this patent, and the accompanying drawings, is simply to fix the projection device and the sound device to a pull-rod sound box, each working separately, without linkage or other design that is beneficial to improving the viewing experience. When a user uses the device, the user needs to independently start the projector and find a curtain which can be hung on a playing field, and the process is tedious, time-consuming and labor-consuming. In addition, in the patent, as the ultra-short-focus projector is adopted, a special curtain body is required to be equipped when the projector is used, so that the outdoor pull rod loudspeaker box laser projector can be normally used. In addition, because the curtain body and the outdoor pull rod loudspeaker box laser projector are respectively arranged, the occupied space is increased, and the portability is poor. Furthermore, because the curtain body is placed independently, the curtain body needs to be additionally provided with a bracket to help the curtain body to be spread, so that the burden is increased, and the portability of the equipment is reduced. Therefore, the actual situation is often hundreds in application, the user experience is poor, and the application environment of the outdoor pull rod loudspeaker box laser projector is very limited.

Therefore, the current outdoor audio-visual equipment has the characteristics of convenience in use, portability, low cost and rapidness in mounting, has the problems of narrow application range, poor convenience and poor look and feel, cannot meet the use requirements of people, and also needs to improve the prior art to provide a more reasonable scheme, thereby solving the technical problems existing at present.
