Description

Be provided with the music rule sense breast massager of power amplifier

This utility model relates to a kind of daily health caring articles for use, particularly a kind of utensil that is used for the female breast massage.

The kind of existing breast massager is a lot: electronic breast massager is to adopt the driven by motor eccentric, and the vibration that utilizes eccentric to produce again reaches the effect of vibromassage.Pneumatic breast massager then is in the cup of medicated bra air bag to be set, and allows flexible expansion of air produce the effect of massage by manual or air pump compression, or the like.Although its functional effect is uneven, the shortcoming of following three aspects can be proposed:

1, masseur is just massaged breast simply, lacks the element of music, fails the melody of music artistic charm dynamic and music itself is incorporated in the process of massage.

2, the sensation of the vibromassage administration of human of masseur is not very comfortable.

3, the dull shortage of the frequency of vibration of masseur changes.

The patent application " music rule sense breast massager " of together submitting with this utility model has solved three shortcomings set forth above preferably, it is by two massaging bodies, coupling mechanism between two massaging bodies, fixing band, plain conductor is formed, its massaging body comprises speaker, massage cushion and washer arrangement, on the diaphragm of loudspeaker, be fixed with massage cushion, horn mouth bracket end device at speaker has scalable or washer arrangement unadjustable and speaker relative distance, be connected between two massaging bodies be unadjustable or scalable two massaging bodies between the coupling mechanism of phase mutual edge distance.It allows women's user experience a kind of brand-new breast massager by adopting speaker for massage power.But, the power amplifier that needs certain output in use is used, and when not having powerful power amplifier equipment, breast massager just can not be worked, and especially can not drive the work of music rule sense breast massager by resembling small-power sound appliances such as some small-sized walkmans, radio cassette player.

The purpose of this utility model is by in the circuit of music rule sense breast massager a power amplifier being set, allowing people just can restrain the sense breast massagers in many local music of using by resembling small-power sound appliances such as some small-sized walkmans, radio cassette player.

The purpose of this utility model is achieved through the following technical solutions:

The schematic diagram of Fig. 2, this New type of S TK4141 double track integrated power amplifying circuit

Below in conjunction with drawings and Examples this utility model is further described:

As shown in Figure 1, input signal amplifies through power amplifier earlier, and then is input to music rule sense breast massager.As shown in Figure 2, its STK4141 double track thick film integrated circuit is compared with general integrated amplifier circuit, has that volume is little, an output big (2*25W), characteristics such as easy for installation, and has the function of cutting off open and close machine impact noise.The principle of this cancellation open and close impact noise is an ON-OFF control circuit of utilizing the integrated package indoor design, cuts off the power amplifier prestage when start (or shutdown) earlier, and power amplifier is connected in delayed then back, thereby eliminates the impact noise that open and close machine moment causes.Its delay action is mainly realized by diode 2EG parallel resistor 2R4 (180k) among Fig. 2 and electric capacity 2C1 (33u).The controlled terminal of STK4141 is 6 feet.When start, negative supply voltage from power rectifier output is added to 6 feet by resistance 2R1 (22k) earlier, the prestage of STK4141 power amplifier is not disconnected because of there being biasing, and just be added to control end 6 feet after by the delay of above-mentioned 2R4 (180k) and 2C1 (33u) through 2R2 (4.7k) by the positive voltage of power rectifier output, through after a while, making 6 foot current potentials when the stack of generating positive and negative voltage is timing, and the prestage in the integrated package is just connected operate as normal, thereby has avoided VGA CARD.When shutdown, then utilize diode 2EG that positive voltage is discharged rapidly, making control end 6 feet is nagative potential, thus the prestage of power amplifier is cut off earlier when guaranteeing shutdown, avoids producing the shutdown impact noise.

The functions of pins of STK4141 is: 1, input 1,2, feedback 1,3,16 earth terminals, 4, outer meeting resistance to 7 foot is for constant current tube provides bias loop, 5, outer meeting resistance and provide the biasing path for inner sound channel 1 underarm outlet tube, 6, squelch control, 7, outer meeting resistance to 4 foot is for constant current tube provides bias loop, it also is the emitter terminal of internal electron switching tube, 8, internal electron switching tube base terminal, 9,14 power amplifier level-Vcc, 10, output 1,11, power amplifier level+Vcc, 12, prime+Vcc, 13, output 1,15, outer meeting resistance provides the biasing path for inner sound channel 2 underarms, 17, feedback 2,18, output 2.

The function of its main element is: R1 (1k), C2 (2.2u) and R12 (1k), C11 (2.2u) be about the input Rhizoma Nelumbinis close resistance capacitance; C1 (470p), R2 (56k) and C10 (470p), R13 (56k) are left and right sides input grounding resistance capacitances; R11 (100) is the Vcc isolation resistance, and C8 (100u), C9 (10u) are that power Vcc is removed Rhizoma Nelumbinis electric capacity; R10 (10), C7 (0.047u) and R18 (10), C14 (0.047u) be used for respectively proofreading and correct about output phase shift, make load approach pure resistance; C5 (0.1u) is used to suppress the high-frequency self-excitation vibration; 3, the 16th, earth terminal; 4,7 go-and-retum outer meeting resistance R7 (100), and constitute bias loop, and be connected with partially installing capacitor C6 (47u), C13 (47u) respectively with left and right sides outfan with 5 end outer meeting resistance R5 (2.2k), R6 (2.2k) and 15 end outer meeting resistance R16 (2.2k), R17 (2.2k); R4 (56k) and R3 (680), C3 (100u) constitute L channel output negative-feedback circuit, and R15 (56k) and R14 (680), C12 (100u) constitute R channel output negative-feedback circuit; R8 (1k), R9 (1k) are base resistances, and C18 (10u) is a filter capacitor, and C15, C16, C17 are power filtering capacitors; Circuit in its frame of broken lines is foregoing holding circuit.

This is novel by in the circuit of music rule sense breast massager an integrated power amplifier being set, thereby does not need powerful sound equipment power amplifier, as long as just can work by small-power sound appliances such as resembling some small-sized walkmans, radio cassette player simply.Thereby for user is provided convenience at the more local music rule sense breast massager that uses.
