Description

Technical Field

[0001] The invention relates to a speaker, in particular to a multi-channel speaker with an adjustment function. Background Art

[0002] Audio electronics refers to a device that uses electronic circuit design to convert audio and electronic signals. However, in general speaking, audio usually refers to a set of equipment that can restore and play audio signals. Audio equipment generally includes power amplifiers, peripheral equipment (including compressors, effectors, equalizers, VCDs, DVDs, etc.), speakers (speakers, speakers), mixers, etc. The development history of audio technology can be divided into four stages: electron tubes, transistors, integrated circuits, and field effect transistors. Audio is divided into single-channel audio, dual-channel audio, and multi-channel audio. As people's pursuit of sound quality becomes higher and higher, the application of multi-channel audio is becoming more and more extensive.

[0003] When existing personnel use multi-channel speakers, it is not convenient to adjust their height, and it is also not convenient to adjust their direction, which is inconvenient to use.

[0014] When the gear is engaged with the rack, the gear drives the rack to move. When the rack moves upward, the rack moves upward with the fixed vertical plate. When it moves upward, the second inclined portion pushes the first inclined portion, thereby causing the second sliding rod to drive the third supporting block to slide along the supporting seat. The third supporting block squeezes the second spring to contract it, thereby causing the clamping block to move out of the groove, so that when the fixed vertical plate moves upward, the clamping block does not cause positioning in the groove. When it moves to the required height, the handle is no longer shaken, and the second spring elastically extends to push the second sliding rod and the third supporting block to bring the clamping block closer to the groove. When the clamping block is inserted into the corresponding groove, the first horizontal portion is fitted with the second horizontal portion, and the clamping block is clamped with the groove, thereby keeping the fixed vertical plate at the current height and no longer moving, thereby facilitating the adjustment of the height of the multi-channel audio body according to usage needs.

[0015] 2. The horizontal axis is driven to rotate by rotating the handle, and then the second bevel gear is driven to rotate the first bevel gear. The first bevel gear drives the vertical axis to rotate, and then the supporting circular plate is driven to rotate, and then the multi-channel audio body is driven to rotate, so that the direction of the multi-channel audio body can be adjusted according to the needs of use.

[0016] 3. The buffer block and the first spring are used to buffer the impact force when the first support horizontal plate moves downward and contacts the buffer block, thereby reducing the risk of damage to the multi-channel audio body caused by the impact force.

[0025] The working principle of the present invention is:

[0026] When in use, the connecting shaft 25 is driven to rotate by shaking the crank 28, and the gear 24 is driven to rotate by the connecting shaft 25. Due to the meshing cooperation between the gear 24 and the rack 23, the gear 24 drives the rack 23 to move. When the rack 23 moves upward, the rack 23 moves upward with the fixed vertical plate 27. When moving upward, the second inclined portion 32 pushes the first inclined portion 31, so that the second slide bar 18 drives the third support block 21 to slide along the support seat 20. The third support block 21 squeezes the second spring 19 to make it contract, so that the clamping block 26 moves out of the groove 22. When the fixing vertical plate 27 moves upward, the clamping block 26 does not position the groove 22. When the fixing vertical plate 27 moves to the required height, the crank handle 28 is no longer shaken, and the second spring 19 elastically extends to push the second slide bar 18 and the third support block 21 to make the clamping block 26 close to the groove 22. When the clamping block 26 is inserted into the corresponding groove 22, the first horizontal portion 30 and the second horizontal portion 33 are fitted, and the clamping block 26 is clamped with the groove 22, so that the fixing vertical plate 27 is kept at the current height and does not move, so that the multi-channel audio body 1 can be easily adjusted according to the use needs. The height of the multi-channel audio body 14 can be adjusted by rotating the handle 9 to drive the horizontal shaft 10 to rotate, thereby driving the second bevel gear 13 to rotate the first bevel gear 2, and the first bevel gear 2 drives the vertical shaft 1 to rotate, thereby driving the supporting circular plate 11 to rotate, and then driving the multi-channel audio body 14 to rotate, so as to facilitate the adjustment of the direction of the multi-channel audio body 14 according to the use needs, and the second slide bar 18 and the third support block 21 are driven to move by pulling the handle 17, and the third support block 21 slides along the support seat 20, thereby squeezing the second spring 19, so that the clamping block 26 moves from The first support plate 7 and the first spring 16 are used to move the first support plate 7 back and forth, and the first support plate 7 and the first support circular plate 11 are used to move out of the groove 22, and at the same time, the connecting shaft 25 and the gear 24 are driven to rotate by shaking the crank handle 28 in the opposite direction, thereby driving the rack 23 to move slowly downward, and then the first support cross plate 7 and the support circular plate 11 move downward, so that the first support cross plate 7 falls back and moves closer to the buffer block 15, thereby facilitating the downward movement of the multi-channel audio body 14, and through the coordinated arrangement of the buffer block 15 and the first spring 16, the impact force when the first support cross plate 7 contacts the buffer block 15 when moving downward is buffered, thereby reducing the risk of damage to the multi-channel audio body 14 caused by the impact force.
