Description

Volume adjustment device

Technical field

The present invention relates to a kind of volume adjustment device, particularly relate to a kind of volume adjustment device of single button.

Background technology

Current, when utilizing the volume of button adjustment electronic installation, be usually provided with two buttons on the electronic device, one increases for regulating volume, and one reduces for regulating volume.But along with electronic installation is towards lightening development, it is lightening further that the setting of two buttons hinders electronic installation.

Summary of the invention

For above-mentioned the deficiencies in the prior art, be necessary the volume adjustment device that a kind of single button is provided.

A kind of volume adjustment device, comprise button, volume control unit, trigger end, the first link and the second link, this first link and the second link are all electrically connected at volume control unit; When pressing this button to primary importance, this trigger end is electrically connected on the first link, triggers the first volume control signal to volume control unit; When this button of further pressing is to the second place, this trigger end disconnects and the electrical connection of the first link and being electrically connected with the second link, triggers the second volume control signal to volume control unit.

Described volume adjustment device achieves the adjustment of volume by single-button, thus reduces volume and saved cost.

Accompanying drawing explanation

Fig. 1 is the structural representation of the volume adjustment device of better embodiment of the present invention.

Main element symbol description

Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.

Embodiment

Refer to Fig. 1, the volume adjustment device 100 of better embodiment of the present invention, realizes the adjustment of volume for single-button, and this volume adjustment device 100 comprises button 10, trigger end 20, first link 30, second link 50 and volume control unit 60.

Button 10 is for contacting pressing, to realize the adjustment of volume for user.

Trigger end 20 is fixedly connected on button 10, comprises the first triggering section 21 and second and triggers section 22.Trigger end 20 moves along with the pressing of button 10, and this trigger end 20 grounding.

This first link 30 and the second link 50 are all electrically connected at volume control unit 60, and be arranged at intervals on the path of trigger end 20 movement successively, under trigger end 20 drives, trigger the first volume adjustment signals and the second volume adjustment signals respectively to volume control unit 60.

In the present embodiment, this first link 30 comprises the first shell fragment 31 and the second shell fragment 32.First shell fragment 31 and the second shell fragment 32 interval are arranged, thus form a passage 34 between the first shell fragment 31 and the second shell fragment 32.First shell fragment 31 can first trigger section 21 supporting under generation strain; Second shell fragment 32 can second trigger section 22 supporting under generation strain.This passage 34 is for passing through for trigger end 20.When the first shell fragment 31 and the second shell fragment 32 are positioned at original position, the distance between the first shell fragment 31 and the second shell fragment 32, namely the width of passage 34 is less than the length of trigger end 20.When trigger end 20 supports the first link 30, trigger end 20 is electrically connected at the first link 30.

Second link 50 and the first link 30 interval are arranged, and the first link 30 is between trigger end 20 and the second link 50.When trigger end 20 supports the second link 50, trigger end 20 is electrically connected at the second link 50.

Volume control unit 60, for regulating volume, comprises volume and increases end 61 and volume down small end 62.Volume increases end 61 and volume down small end 62 is electrically connected at the first link 30 and the second link 50 respectively, increases operation, receive the second volume adjustment signals and reduce operation to realize volume to receive the first volume adjustment signals respectively to realize volume.In the present embodiment, this volume increase end 61 is electrically connected to the first shell fragment 31 and the second shell fragment 32.

Further illustrate the use principle of volume adjustment device 100 of the present invention below.

When needs realize volume increase, pressing keys 10 makes trigger end 20 support and keeps being electrically connected at the first link 30, concrete, and the first triggering section 21 is held in the first shell fragment 31, second triggering section 22 and is held in the second shell fragment 32.Now, volume increases end 61 and triggers low level first volume adjustment signals by the first link 30 with trigger end 20 ground connection successively, realizes volume and increases operation.

When needs realize volume down hour, pressing keys 10 makes trigger end 20 cross the first link 30, supports and keep being electrically connected at the second link 50.Concrete, pressing keys 10 makes first of trigger end 20 to trigger section 21 and is held in the first shell fragment 31, second triggers section 22 is held in the second shell fragment 32, continuing pressing keys 10 again makes trigger end 20 force the first shell fragment 31 and the second shell fragment 32 that strain occurs, passage 34 broadens, until trigger end 20 is through this passage 34, supports and keep being electrically connected at the second link 50.Now this first triggering section 21 and second triggers section 22 homing and disconnects the electric connection with trigger end 20, volume down small end 62 triggers low level second volume adjustment signals by the second link 50 with trigger end 20 ground connection successively, realizes volume and reduces operation.

Be appreciated that, this first link 30 is not only confined to the structure comprising the first shell fragment 31 and the second shell fragment 32, as long as this first link 30 can reach to support with trigger end 20 be electrically connected and further pressing keys 10 time, support with the second link 50 after this trigger end 20 can leave the first link 30 and be electrically connected.As, in another embodiment, trigger end 20 only includes the first triggering section 21, first link 30 and only includes the first shell fragment 31, first shell fragment 31 and the second link 50 all has at least a part to be positioned on the stroke of the first triggering section 21.

Be appreciated that this volume adjustment device 100 can comprise a reposition element further, be connected with button 10 or trigger end 20.When this button 10 is pressed to regulate volume, this reposition element gathers elastic force simultaneously.After this button 10 is discharged by user, this reposition element can discharge its elastic force and drive this button 10 and trigger end 20 homing, to terminate the operation to volume.

Described volume adjustment device 100 achieves the adjustment of volume by single-button, thus reduces volume and saved cost.
