Projector with extended function interface and projector device

Abstract

The invention discloses a projector with an extended function interface and a projector device. The projector device comprises a projector and an extended function module, wherein one or more standardinterface male sockets for inserting the extended function modules are arranged in a projector shell; a standard interface female socket is arranged on the extended function module; and when the standard interface female socket is inserted into the standard interface male socket, the extended function module is connected with and paired with the projector. According to the invention, a terminal user and a seller can select the projector and the function module which accord with the interface definition and the design specification according to the function requirements, and the function is realized through matching; and finally, the cost of research and development, production, subsequent system upgrading and after-sales maintenance is saved for consumers and manufacturers, and meanwhile,the cost and stocking risk of the manufacturers and the agents are reduced in the production management and sales links.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a projector with an extended function interface and a projector device. Background technique [0002] During the use of existing projectors, they all need to be used with the corresponding playback content source equipment. The common form is to provide various input and output interfaces on the projector, requiring users to connect their personal computers or wireless projection TV sticks Or a network media player or a high-definition digital media player or a digital TV set-top box is connected to the corresponding audio and video input interface socket of the projector through various connecting wires. This structure and connection form has the defect of poor integrity. Many users do not know how to connect the various independent functional devices they need, and the connection lines affect the appearance. When operating at the same time, more than two remote controls or o...

This structure and connection form has the defect of poor integrity. Many users do not know how to connect the various independent functional devices they need, and the connection lines affect the appearance. When operating at the same time, more than two remote controls or other control devices are often required.

Another form is directly equipped with a computer or wireless projection screen or network media player or high-definition digital media player or digital TV receiving circuit on the motherboard inside the projector case; and with the increasing demand for additional functions, the equipment Design and manufacturing manufacturers need to establish different projects for management and control, design different circuit board programs and housings in projectors with the same shape, and conduct phased development and verification of each project; the complexity of production assembly test verification and inventory management has doubled, Greatly increase the cost of design and manufacturing; it will also increase the inventory capital cost of products with the same appearance but different functions for the business department, and increase the risk of sales forecast and the difficulty of after-sales
