Abstract
The utility model discloses an electronic sound pickup device for a stringed instrument, which belongs to the field of stereo equipment. A mini-transmitter is embedded into the bottom of a string bridge; a lead plug of a tone controller is connected to the transmitter; the circuit of the tone controller adopts the following connection mode: the external electrodes of a jack A and a jack B are connected through a lead; a capacitor C is serially connected between the elastic sheet electrodes of the jack A and the jack B; the lead led out of the external electrode of the jack B is connected with one pole of a battery, and the other pole of the battery is connected with one end of a variable resistor; the other end of the variable resistor is connected with the elastic sheet electrode of the jack A; and the outgoing line of the connection line between the elastic sheet electrode of the jack A and the capacitor is connected with a movable contact of the variable resistor. The device with small size can send sound to a sound console and a sound box for amplification when attached to a resonator of the stringed instrument, and also can adjust the tone quality and filter out noise. In addition, the device not only maintains the flexibility and convenience of the original performance, but also improves the stereo effect when in wired or wireless connection with playback equipment.
Description
1, technical field: the utility model relates to the sound pick up equipment that a kind of stereo set is used, especially for a kind of sound pick up equipment of stringed musical instrument.
2, background technology: wide many occasions seem in the hall that some is faint in the pronunciation that stringed musical instrument is played, and in order to amplify sound equipment, will be placed on microphone near the musical instrument sometimes, and stringed musical instrument player's activity is restricted.Can have during the song microphone handholding singing and move or walk about, and plucked stringed instrument or guitar player can not be with the microphone activity, very inconvenient.
3, summary of the invention: the purpose of this utility model is a kind of stringed musical instrument electronics sound pick up equipment of design, and this device can amplify playing sound by sound console and resonant tank, makes things convenient for the movable and performance of player again.For realizing this purpose, adopted such technical scheme: scheme one, post the sheet hummer in string numeral bottom surface, hummer has the line trap that connects audio frequency adjusting box.Lead is connected between the circuit connection-jack A of audio frequency adjusting box and the external electrode of jack B, and its extension line that connects lead connects variable resistor one end, and the variable resistor other end connects the shell fragment electrode of jack A.The shell fragment electrode of jack B connects variable-resistance armature contact.Between jack B external electrode extension line and jack B shell fragment electrode outlet line, be parallel with C1 and two electric capacity of C2.Scheme two is embedded with miniature transmitter in string numeral bottom, and the line trap that connects tone control is arranged on the transmitter.The circuit of tone control connects, lead is connected between the external electrode of jack A and jack B, the capacitor C of contacting on the shell fragment electrode connecting line of jack A and jack B, wire connected battery one utmost point that jack B external electrode is drawn, another utmost point of battery connects variable resistor one end, the variable resistor other end connects the shell fragment electrode of jack A, and the shell fragment electrode of jack A is connected variable-resistance armature contact with the extension line of capacitor connection.
Stringed musical instrument electronics sound pick up equipment volume is small and exquisite, attached to sound being sent to sound console on the stringed instrument resonator and audio amplifier is amplified, can also regulate tonequality filtering noise simultaneously.Can adopt wired or wireless the connection with tone playing equipment, both keep original performance flexibility, increase acoustics again.
4, description of drawings: Fig. 1 is a stringed musical instrument electronics sound pick up equipment fundamental diagram.Fig. 2 is stringed musical instrument electronics sound pick up equipment first scenario-frame and wiring diagram.Fig. 3 is stringed musical instrument electronics sound pick up equipment alternative plan structure and wiring diagram.
5, embodiment: be further described below in conjunction with accompanying drawing.Stringed musical instrument electronics sound pick up equipment comprises the string numeral 1 and the audio conditioning apparatus 3 of band pickup parts 8, and the audio conditioning apparatus volume is small and exquisite, sticks on the resonant tank of plucked stringed instrument to be connected with the pickup parts plug 2 of string numeral, and its principle of work as shown in Figure 1.Audio conditioning apparatus 3 connects sound console 6 and audio amplifier 7 by lead, the qin sound of playing can be amplified.Perhaps, audio conditioning apparatus connects small-sized signal transmitter 4, and the player takes transmitter with oneself, connects sound console and audio amplifier by wireless receiver 5, and same effect is also arranged.
Embodiment has two kinds, and scheme one is posted sheet hummer 9 in string numeral 1 bottom surface as shown in Figure 2, and hummer has the line trap that connects audio frequency adjusting box.The circuit connection that audio frequency is regulated box 11 is: be connected by lead between the external electrode of jack A and jack B, its extension line that connects lead connects 50K variable resistor one end, and the variable resistor other end connects the shell fragment electrode 10 of jack A.Changing resistance value can regulate tonequality by regulation voltage, removes noise.The shell fragment electrode of jack B connects variable-resistance armature contact.Between jack B external electrode extension line and jack B shell fragment electrode outlet line, be parallel with 0.47 microfarad C1 and two electric capacity of 103 microfarad C2.Change capacitance and also can change tonequality, debugging determines that back C1, C2 have adopted fixed capacity.
Scheme two is embedded with the miniature transmitter 12 that mobile phone is used in string numeral 1 bottom as shown in Figure 3, and the line trap that connects tone control is arranged on the transmitter.The circuit of tone control 13 connects: lead is connected between the external electrode of jack A and jack B, polyphone 10 microfarad capacitor C on the shell fragment electrode connecting line of jack A and jack B, the wire connected battery negative pole that jack B external electrode is drawn, anode connects 50K variable resistor one end, the variable resistor other end connects the shell fragment electrode 10 of jack A, and the shell fragment electrode of jack A is connected variable-resistance armature contact with the extension line of capacitor connection.
