Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
A kind of electronics drum is based on wire side as drum head, and places a drum head and knock pick-up unit in the drum framework, and it is in order to detecting from the knocking of drum head, and knocking is converted to electric signal, is sent to sound source chip.
What deserves to be mentioned is that described drum head is made by Web materials.Web materials can obtain the fabulous feel of knocking.In addition, because air can be from the network interface convection current of Web materials, the clash that knocks drum head can become very little.
Fig. 1 is the synoptic diagram of described electronics drum, and this electronics drum 14 comprises: netted drum head 13, and drum framework 3, drum head knocks pick-up unit 11.
Described netted drum head 13 is made by Web materials.
Described drum head knocks pick-up unit 11, places within the bulging framework 3, and is contacted with the lower surface of netted drum head 13.
Described drum head knocks pick-up unit 11, and the signal wire 12 of its sensor 2 knocks the pick-up unit 11 from drum head and stretches out, and is connected in the sound source chip (not shown), knocking be converted to electric signal and be sent to sound source chip.
Fig. 2 has done structural representation for the drum head among Fig. 1 knocks pick-up unit 11, and it is by hard material 1, and sensor 2 and supporting structure 5 thereof are formed, and sensor 2 depends on the lower surface of hard material 1, and is supported by its supporting structure 5.
Wherein, described supporting structure 5 comprises, buffer body 6, peripheral circle body 4, cushion 8, supporting spring 9, bracing frame 10.Hold buffer body 6 on the supporting spring 9, peripheral circle body 4 and cushion 8, and supported 10 from supported underneath are with the fixing (not shown) of the screw of bracing frame by both sides.
Supporting spring 9 can be made by rigid material, as iron plate etc.
Described sensor 2 is cushioned body 6 and supports, and is close to hard material 1 lower surface.Simultaneously, hard material 1 contacts with netted drum head 13.In other words, sensor 2 is placed on the lower surface of netted drum head 13 together with hard material 1.
Specifically and since hard material 1 be covered in sensor 2 directly over, and contact with the lower surface of netted drum head 13, knock the vibration that netted drum head 13 brings and can directly be sent to sensor 2.Therefore, compared to using flexible material or buffer body to place scheme on the sensor, use the present invention, hard material is covered on the sensor, and buffer body places under the sensor, and the vibration of drum head will directly be passed to sensor, and it is minimum to decay.
Corresponding buffer body place on the sensor or under, more different impulse forces collide netted drum head, the output situation of sensor.Use table tennis from the certain altitude freely falling body to described netted drum head center, the output signal peak value of read sensor from the oscillograph.The output voltage situation of sensor is as shown in the table:
| Table tennis height (cm) | Buffer body places (unit: V) under the sensor | Buffer body places (unit: V) on the | Ratio | |

| 30 | 2.1 | 1.6 | 1.31 | |
| 40 | 2.48 | 2.0 | 1.24 | |
| 50 | 3.3 | 2.4 | 1.38 | |
| 60 | 3.7 | 2.6 | 1.42 | |
| 70 | 4.2 | 2.7 | 1.56 |
Find out that from above data compared to using flexible material or buffer body to place scheme on the sensor, use the present invention, hard material is covered on the sensor, buffer body places under the sensor, and its sensor output signal increases about 35%.On the one hand, for the less vibration from drum head, the signal of sensor output is bigger, that is to say that knock for drummer's little dynamics, sensor is easier to be detected, and its sensitivity is higher.On the other hand, for the bigger vibration from drum head, its decay of signal of sensor output is littler, and promptly the great dynamics for the drummer knocks, and its dynamic range is bigger.Simultaneously, vibration transfer to the time of sensor can reduce, and for knocking fast of drummer, can be delivered to sensor with not being delayed and export electric signal to the source of sound sounding, and therefore, the drummer can hear the drumbeat sound that knocks fast at once.Above scheme is based on drummer's the custom of knocking, the drummer is easy to perceive for the delay of knocking fast, postpone pronunciation if knock fast, can cause the drummer to hesitate, and then change its follow-up rhythm that knocks unconsciously, thereby influence whole playing effect, by this scheme, to satisfy the drummer for the perception demand of knocking fast.
On the other hand and since hard material 1 place sensor 2 directly over, and contact with netted drum head 13, knocking of netted drum head 13 directly do not knocked on the surface of sensor 2, therefore, protected sensor 2 to avoid knocking damage.
Described buffer body 6 is contacted with the lower surface of sensor 2, and fixedly places on the supporting spring 9.Because buffer body 6 is a flexible material, and fills up in the sensor lower surface.When knocking bulging face, the vibration of sensor is cushioned body 6 and absorbs.Therefore, protected sensor 2 to avoid knocking damage.
Buffer body 6 can be made by sponge or similar material.
Described cushion 8 places on the supporting spring 9, and together with metal dottle pin 7 by bolt in supporting spring 9, be used for vibration isolation.Correspondingly, be fixed with cushion and metal dottle pin (not shown) equally in order to vibration isolation at the lower surface of supporting spring 9.Specifically, when knocking bulging limit, the vibration on drum limit brings bulging frame and the vibration of drum base, and then drives supporting spring 9 vibrations.By the above-mentioned cushion of mentioning, be partially absorbed and isolate from the vibration of supporting spring 9, and the vibration that is not absorbed by cushion can be absorbed by buffer body 6, relies on the dual absorption vibration of cushion and buffer body 6, can effectively isolate bulging limit vibration transfer to sensor 2.In other words, when knocking bulging limit, drum limit vibration transfer is given in order to detect other sensor (not shown) that knock on bulging limit, this sensor output signal triggers drum lateral look to sound source chip, sensor 2 is close to does not have signal output, and then the possibility of false touch swell face tone color is lowered or avoids.
Cushion 8 can be made by silica gel or similar material.
The signal wire 12 of described sensor 2 penetrates to buffer body, and stretches out from the crevice place of this buffer body, and is connected in the sound source chip (not shown).By the crack of this buffer body, signal wire 12 is protected and is fixing.
Described peripheral circle body 4, fixedly place supporting spring 9 tops and surround sensor and buffer body around become a circle.When great dynamics knocked netted drum head, the sagging degree of depth of drum head was inhibited.Therefore, the protection drum head excessively sink when bringing damage, is also protected sensor.
Aforesaid structure, when using the drum rod to knock netted drum head 13, sensor 2 detects knocking from drum face or drum limit.When using the wire brush brush to hit netted drum head 13, sensor 2 detects contacting between wire brush and the netted drum head 13.
Aforesaid structure, when netted drum head tensioning, hard material is contacted with the drum head lower surface naturally together with sensor, place the sensor 2 on the buffer body, detection is knocked from netted drum head, and knocking is converted to electric signal, is sent to sound source chip by signal wire 12.
Sensing device can be made of hard material and sensor, also can be sensor.
Fig. 3 has showed an alternative embodiment of the invention, uses sensor as sensing device.Because the sensor below is equipped with buffer body, so sensor is difficult for damaging because of knocking.Simultaneously, because sensor directly is contacted with netted drum head lower surface, the detection sensitivity height of sensor, the pressure that sensor is subjected to is not attenuated, and amplitude output signal is big.On the other hand, postpone to be improved compared to using flexible material or buffer body to place scheme on the sensor, knocking.
By the invention described above " a kind of electronics drum ", knock pick-up unit with wire side as the drum head drum head built-in and form with it, come realistic simulation primary sound jazz drum sounding with electroacoustic.Open after on the drum frame when wire side, can be as traditional drum head when hitting, send tum.And the present invention is simple in structure, and handling ease is with low cost.
