Abstract

The utility model discloses a novel display base. A vibration generating driver is fixed in an empty cavity inside the outer casing of the base, through holes are arranged on the base plate of the outer casing, an end of a shaking conveying body is fixed with the vibration generating driver through the through holes and the other end is contacted with rigid media. During the work, after audio frequency is amplified by a power amplifier, the vibration generating driver installed in the empty cavity of the base is ensured to generate vibration, and the vibration are transferred to the surface of a rigid article (such as the surface of a desk) through a shaking conveying flake so that the rigid article is ensured to generate vibration and sound. The display base disclosed by the utility model ensures the original mono-functional display base to be provided with more practical function and solves the problem that other audio frequency devices occupy the space of a desk.

Description

A kind of new display audio frequency base

Technical field

The utility model relates to display and stereo set field, but is the new display audio frequency base about a kind of novel playing back music specifically.

Background technology

In today of each electronic product high speed development, computer has become the necessary article that we work and live, and people have also had higher requirement for the appearance design and the functional configuration of PC.By the base of personal computer monitor, at present, plastics or the metallic article of our employed personal computer monitor base great majority for coming in every shape, function singleness just plays the effect of support displays, and a lot of additional functions are not used wherein.

The utility model has related to Drive Structure that a kind of novel display base can shake sounding and has packed in the base, makes base not only have supporting role, also with the effect that can play sound.Computer is incorporated in people's work and the life better, accomplishes dual-use material, thus make display more humane, have more recreationally, and reduced other audio frequency apparatuses and taken the desk-top space problem.

Summary of the invention

The purpose of this utility model provides a kind of with the display base that can play sound, and makes the display base of original function singleness have more utility function, has reduced other audio frequency apparatuses and has taken the desk-top space problem.

The technical scheme that realizes above-mentioned purpose is: a kind of new display audio frequency base, comprise the display base shell, the balanced support foot pad, driver takes place and passes the shake body in vibration, driver takes place and is fixed in the cavity of enclosure in vibration, have through hole on the shell bottom plate, biography shake body one end passes through hole and fixes with vibrations generation driver, and the other end contacts with rigid media.When this used novel work, audio signal made the vibration generation driver that is installed in the base cavity pocket produce vibration after power amplifier amplifies, and vibration is delivered to rigid objects surface (as table surface) via passing the shake sheet, makes rigid objects produce vibration sounding.The utility model has following advantage:

1, under the prerequisite that does not influence the base basic function, realized the variation of display base function, make base not only have supporting role, also with the effect that can play sound.

2, simplified the connection of whole computer system, omitted a lot of numerous and diverse connection lines, the error rate that computer is connected reduces.

3, of the present utility model simple in structure, adjusting and easy to maintenance, with low cost, volume is little, does not influence former profile during installation.
