Description
Technical field
The utility model relates to mellotron technical field, is specially a kind of touch mellotron using earphone.
Background technology
Mellotron, as the product of science and technology with music, creates the tone color that other musical instruments many cannot be played, even naturally non-existent tone color.The invention of mellotron has promoted the universal of music, and it allows music really become popular music, becomes the thing that human society is indispensable.
But mellotron is usually expensive in daily life, and volume is large, and button is many and loaded down with trivial details, and not easily beginner is simply familiar with study to mellotron.Button on its operation control panel of mellotron is traditionally contact conducting silica gel key, and easily come in contact bad problem, serviceable life is short, causes the waste of resource.For some capacitive touch panels, because electric capacity changes with the difference of temperature, humidity or Grounding, therefore its less stable, often produce drift phenomenon.
Now mellotron commercially all needs 220V AC-powered usually, not only has security hidden trouble, and because the reason in place or other ignorance factors can not provide 220V power supply in scene, can cause very large inconvenience.
Utility model content
The technical matters that the utility model solves is to provide a kind of touch mellotron using earphone, to solve the problem proposed in above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions: a kind of touch mellotron using earphone, comprise: support, touch display screen, described touch display screen is arranged on the upper end of support, touch display screen lower end is provided with microprocessor, described microprocessor is connected with infrared sensor, power module, loudspeaker and earphone interface, USB interface, described infrared sensor is arranged on support and touch display screen junction, USB interface is connected with Bluetooth communication modules and SD storage module.
Described power module comprises transformer, current rectifying and wave filtering circuit, lithium battery, lithium battery charging circuit.
Described support both sides are provided with expansion key module, are connected and fixed between expansion key module by connecting circuit and clip device.
Compared with prior art, the beneficial effects of the utility model are: the utility model can solve Power supply problem, when lacking 220V and powering, can do by myself and are automatically converted to use lithium battery power supply; The infrared sensing module used, extends the serviceable life of touch key-press greatly; The touch panel adopted can keep electronic panel clean, clean and tidy again can dust-proof, waterproof; Realize good human-computer interaction interface according to touch-screen, be applicable to different crowds and use, electronic organ bracket has USB device, facilitates secondary development, and the renewal upgrading of system; Use the bluetooth module of wireless transmission can download new qin spectrum can also to be connected from the different equipment with bluetooth, carry out information interaction, the information of acceptance can be stored in storage module; Can, according to different crowd's needs, expansion module be utilized to expand the key of different quantity.Using method is simple, and cost is low, appearance looks elegant, and reliability is high, and small in volume has more hommization.

Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of touch mellotron using earphone, comprise: support, touch display screen, described touch display screen is arranged on the upper end of support, touch display screen lower end is provided with microprocessor 4, described microprocessor 4 is connected with infrared sensor 2, power module 3, loudspeaker and earphone interface 5, USB interface 6, described infrared sensor 2 is arranged on support and touch display screen junction, USB interface 6 is connected with Bluetooth communication modules and SD storage module.
Described power module 3 comprises transformer, current rectifying and wave filtering circuit, lithium battery, lithium battery charging circuit.
Described support both sides are provided with expansion key module 1, are connected and fixed between expansion key module 1 by connecting circuit and clip device 7.
The utility model is when such as upgrading system or download file, and USB interface 6 links computer, is connected by computer with controller 4, can carry out exchanges data with computer.
When there being 220V power supply, the plug on mellotron can be plugged, after transformer transformation; by rectifier bridge rectification, a stable 5V power supply can be obtained after bulky capacitor filtering and 7805 voltage stabilizing chips, as shown in Figure 2; this power supply not only can be powered to whole system, and simultaneously by TP4055, as shown in Figure 3; to lithium cell charging; this managing chip can protect battery over-discharge, and overvoltage overcharges; excess temperature, can the safety of available protecting battery life and user.Owing to having lithium battery in system, so when without external 220V power supply, system can automatically switch into lithium battery power supply, so just can ensure that whole system can adapt to various occasion.
In the innovation of button, adopt infrared sensing, as shown in Figure 4, solving when the phenomenon of capacitance key less stable and drift and contact conducting silica gel key use can the problem of loose contact and long-time silica gel oxidation.The impact of environmental factor on infrared sensing is lower, it is made up of infrared emission tube and infrared receiver tube, the infrared ray that infrared emission tube sends is reflexed to infrared receiver tube because human body blocks, and by integrated circuit internal feedback signal to microprocessor, releases various music.
Touch-screen there is good interpersonal interactive interface, and can according to different crowds, as beginner, entry level etc., selects one's own pattern.And screen can show qin spectrum, not need to place music stand again.User according to the hobby of oneself, can change the tone color change of each key by change frequency.And have wireless transmission slave one bluetooth module, as shown in Figure 5, and memory module matches, data transmit with the external world, the qin obtained compose be stored in SD, facilitate user often have access to exercise.
Because the demand of difference to key played also need not, so this mellotron is provided with expansion module 1, contact pin and clip is had on the both sides of each touch panel, when needing expansion key, the clip of panel is only needed to buckle, and on two panels, short circuit cap plugged by contact pin, just can realize the connection of two keys and processor.Be convenient to dismounting, easy to carry.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
