Disclosed is a sound mixing console, which comprises an input circuit (1), a main control circuit (2), an output circuit (4) and a power supply circuit (5), and also includes a power amplifier circuit (3) positioned in a case body (7); the input circuit (1) is sequentially connected with the main control circuit (2), the power amplifier circuit (3) and the output circuit (4); and the power supply circuit (5) is connected with the main control circuit (2) and the power amplifier circuit (3). The sound mixing console has the advantages that the sound mixing console has two functions of sound mixing and power amplifier, the volume is small, and the transportation is convenient.
Description
Technical field
The utility model relates to a kind of stereo set that is mainly used in middle-size and small-size mobile performance occasion, specifically is a kind of sound console.
Background technology
The sound console of prior art only possesses the function of sound console, in use needs be used with power amplifier.There is following shortcoming in this sound console:
1, because needs and power amplifier are used,, thereby caused the raising of use cost, also caused the increase of connecting line between the equipment, and then directly had influence on the stability of equipment so the increase of equipment has caused the inconvenience of transportation.
2, owing to adopted toroidal transformer or worker's deformation depressor, so the volume of sound console is big, Heavy Weight is unfavorable for carrying.
3, because the sound console of prior art is not controlled the circuit of radiating fan rotation speed, so the radiator fan of sound console is short useful life, and utilization of power efficient is low.
4, the AB class power amplification efficiency of prior art is low, and caloric value is big, needs heat abstractor preferably, thereby has caused volume big, is unfavorable for carrying and transporting.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of and has sound console and two kinds of functions of power amplifier simultaneously and volume is little, the sound console of convenient transportation.
The technical solution of the utility model is, a kind of sound console with following structure is provided, and it comprises input circuit, governor circuit, output circuit, power circuit; It also comprises the power amplifier that is positioned at same box body; Described input circuit successively with governor circuit, power amplifier, output circuit connects; Described power circuit is connected with governor circuit, power amplifier.Described power circuit refers to hf switching power supply; Described hf switching power supply comprises radiating control circuit; Described power amplifier refers to G class power amplifier.
After adopting above structure, the utility model compared with prior art has the following advantages:
1, owing to the function with a power amplifier is integrated in this sound console, reduces number of devices like this, made things convenient for the equipment transportation, reduced line simultaneously, reduced use cost, improved stabilization of equipment performance.
2, the high frequency switch power that adopts owing to the sound console of being with the power amplifier formula, efficient height, output voltage stabilization, it is little to exchange ripple, and volume is little, in light weight, is easy to carry.
3, owing to adopted radiating control circuit to improve the utilization ratio of electric energy, prolonged the useful life of fan.
4, owing to adopted the G class power amplifier of high efficiency low distortion, reduce volume like this, guaranteed audio.
Description of drawings
Accompanying drawing is that sound console constitutes schematic diagram
Shown in the figure 1, input circuit, 2, governor circuit, 3, G class power amplifier, 4, output circuit, 5, hf switching power supply, 6, radiating control circuit, 7, box body.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The sound console of prior art is a sound console that does not have power amplifier function 3.
The utility model sound console is that power amplifier 3 is integrated in this sound console.As shown in Figure 1, it mainly is made up of several big parts such as input circuit 1, governor circuit 2, G class power amplifier 3, output circuit 4 and hf switching power supplies 5.And above-described circuit is custom circuit.As shown in Figure 1, sound console input circuit 1 is connected to governor circuit 2, and governor circuit 2 is connected to G class power amplifier 3, and G class power amplifier 3 is connected to output circuit 4.When work, multipath signal source from sound console input circuit 1 each individual passage carry out preposition amplification after inserting, signal after amplifying before preposition is sent to the tone adjusting that governor circuit 2 carries out each sound channel, auxiliary output is regulated, delivering to professional sound effect after every road effect signal amplitude is tuning carries out after various sound effects handle, effect signal is carried in L, on the R audio mixing bus, carrying out stereophonic sound image regulates, single passage volume is carried out the multichannel audio mixing after regulating again, and then audio signal is sent into carry out on built-in G class power amplifier 3 parts after the audio signal power amplification signal by output circuit 4 outputs.
High frequency switch power 5 is connected to G class power amplifier 3 and governor circuit 2, is G class power amplifier 3 and governor circuit 2 power supplies.From the alternating current input filter, provide stable DC power supply reliably for sound console through over commutation and filtering, power P WM conversion, output rectification and a series of processes of filtering.Its radiating control circuit 6 is received a PTC thermistor on the power discharging radiator, and the variations in temperature of radiator causes resistance to change, thereby reaches the rotating speed of controlling fan by the mode that changes fan voltage.
The G class power amplifier that the power amplifier of sound console partly uses is connected with governor circuit, output circuit and hf switching power supply respectively.
Claims (4)
1. a sound console comprises input circuit (1), governor circuit (2), output circuit (4), power circuit (5), it is characterized in that: it also comprises the power amplifier (3) that is positioned at same box body (7); Described input circuit (1) is connected with governor circuit (2), power amplifier (3), output circuit (4) successively; Described power circuit (5) is connected with governor circuit (2), power amplifier (3).
2. sound console according to claim 1 is characterized in that: described power circuit (5) refers to hf switching power supply (5).
3. sound console according to claim 2 is characterized in that: described hf switching power supply (5) comprises radiating control circuit (6).
4. sound console according to claim 1 is characterized in that: described power amplifier (3) refers to G class power amplifier (3).
