Embodiment

The present invention will be further described below in conjunction with the accompanying drawings.

If Fig. 1 is front view of the present invention, Fig. 2 is right view of the present invention, and Fig. 3 is the A-A views of Fig. 1.The invention is related to A kind of multi-functional drum, including drum body device 1 and holder device 2, drum body device 1 are installed on above holder device 2.Wherein, it is described Drum body device 1 include drum body 11 and drum body support frame 12, drum body support frame 12 be fixed on the side wall of bulging body 11；Holder device 2 wraps Column 21, kelly fixing device 22 and kelly 24 are included, several small pin holes and a big pin hole are provided with kelly fixing device 22, is blocked Lever fixing apparatus 22 is connected with kelly 24 by small pin hole, and kelly fixing device 22 is connected with column 21 by big pin hole；Kelly 24 with drum body support frame 12 be pin connection.The present invention is easy for installation and removal, fabrication and installation cost is low by pin connection.The drum The quantity of body support frame 12 and kelly fixing device 22 is respectively three or four.Ensure kelly fixing device 22 and kelly 24, stand When column 21 distinguishes pin connection, fixation is played.Minor thread hole, the minor thread hole are set in the kelly fixing device 22 It is vertical with above-mentioned big pin hole to communicate, adjusting bolt 23 is set in minor thread hole.By unscrewing adjusting bolt 23, kelly fixes dress Angle can be adjusted by putting 22 and rousing body device 1, after angle is adjusted, then tightened adjusting bolt 23, fixed the angle of bulging body device 1 Degree, so as to fulfill the adjusting of drum body angle.The bulging body device 1 further includes litter stent 13, and litter stent 13 is fixed on bulging body On the side wall of device 1, microphone is installed outside drum body device 1, litter 15, the top of litter 15 are fixed on litter stent 13 First vibration detection sensor 16 is installed, first vibration detection sensor 16 can be piezoelectric ceramic piece trigger.It is flat When practice or performance when, the first vibration detection sensor 16 collect drum head vibration signal, while drum body device 1 outside Mike Wind collects the voice signal that drum head produces, the first vibration detection sensor 16 and above-mentioned microphone by the vibration signal harmony of collection Sound signal is sent to background server, and is stored in holder, and drummer can hear the sound that server is collected by headset.

If Fig. 4 is the B-B views of Fig. 2, the bulging body device 1 further includes damping disc 14 and damping disc regulating device 17, subtracts Through hole is provided with shake disk 14, damping disc 14 is installed by through hole and litter 15.Damping disc 14 can slide up and down on litter 15. Several large through-holes 141 and several threaded holes 142 are provided with the damping disc 14.In normal play, damping disc 14 is away from upper Lower drum head, while sound equipment is produced to avoid damping disc 14 from shaking upper and lower drum head, large through-hole 141 is set on damping disc 14, is protected Demonstrate,prove sound normal through；When practicing in residential block, damping disc 14 is moved up close to upper drum head, when tapping drum head, damping disc 14 Drum head is blocked, drum head shakes in suppression.Solid section installs soft vibration-absorptive material on the damping disc, can be cotton-wool or Sponge, and the second vibration detection sensor is laid with vibration-absorptive material, in 13 upper surface of litter stent installation first position sensing Device.Second vibration detection sensor is used to practice beating a drum under damping and silencing pattern, when beating a drum in residential block practice, in order to keep away Exempt to disturb residents, drum must be allowed to send larger sound, while in order not to influence to practice, the sound oneself beaten a drum must be listened to Sound.By the second vibration detection sensor, dynamics and preliminary vibration information when detection taps drum head, by contrast device, and just The vibrations that the first vibration detection sensor 16 detects when often beating a drum contrast, and electro-acoustic, therefore drummer are sent by headset Sound interference can will not be produced to the external world while drum is practiced.For the soft damping material of solid section installation on damping disc Material, it is therefore an objective to when mute practice is beaten a drum, dynamics feel when simulation is normally beaten a drum, so that sensation when not influencing practice, separately It can also play the role of protecting drum head outside.

If Fig. 5 is the C-C views of Fig. 2, Fig. 6 is damping disc regulating device structure chart, and the bulging body device 1 further includes damping Disk regulating device 17, damping disc regulating device 17 are fixed on litter stent 13.The damping disc regulating device 17 includes housing 170th, screw 171, polished rod 172, handwheel 173, decelerating motor 174 and transmission mechanism 175, the screw 171 and polished rod 172, Decelerating motor 174 is connected by transmission mechanism 175, and screw 171 and polished rod 172 are mutually perpendicular to, and handwheel 173 is installed on polished rod 172 On；Screw 171 sets electronics clutch through the threaded hole 142 on damping disc 14 between decelerating motor 174 and transmission mechanism 175 Device.The transmission mechanism 175 is intermeshing two angular wheel or worm and gear.Damping disc regulating device 17 of the present invention is divided Manually and automatically both of which, under means state, decelerating motor 174 and transmission are opened by switch button or cell phone application Electric clutch between mechanism 175, when rotating handwheel 173 with hand, polished rod 172 and handwheel 173 rotate together, polished rod 172 Being rotated by the screw 171 of 175 vertical direction of transmission mechanism, the threaded hole 142 on screw 171 and damping disc 14 engages, So as to which damping disc 14 is under the drive of screw 171, upwardly or downwardly move.When damping disc 14 moves upwards, the second place passes When sensor receives inductive signal, electric clutch is closed, and damping disc 14 cannot continue up rotation；When damping disc 14 is transported downwards Dynamic, when first position sensor receives inductive signal, electric clutch is closed, and damping disc 14 cannot continue to rotate down. Under automatic mode, by cell phone application, either switch button sets cell phone application or after switch button sends control signal automatically, Electric clutch closes, and under mute exercise mode, decelerating motor 174 drives electric clutch to rotate forward, and electric clutch rotates forward Transmission mechanism 175 is driven to link, transmission mechanism 175 drives screw 171 to rotate, the threaded hole 142 on screw 171 and damping disc 14 Engagement, damping disc 14 moves upwards under the drive of screw 171, when when the second place, sensor receives inductive signal, slows down Motor 174 stops operating；Under normal exercise mode, decelerating motor 174 drives electric clutch reversion, electric clutch reversion Transmission mechanism 175 is driven to link, transmission mechanism 175 drives screw 171 to rotate, the threaded hole 142 on screw 171 and damping disc 14 Engagement, damping disc 14 moves downward under the drive of screw 171, when when first position, sensor receives inductive signal, slows down Motor 174 stops operating.

Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, in relation to the common of technical field Technical staff, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore all Equivalent technical solution falls within scope of the invention, and scope of patent protection of the invention should be defined by the claims.
