Abstract

The utility model relates to a sound controlling rock music bell, which combines the functions of decoration, furnishing and toys. The utility model is composed of a power supply, a buzzing slice, a music integrated circuit and a power switch which are arranged in a bell shell and a bottom board, besides, the bottom board is also provided with a rock device which is composed of a clapper and a motor and an eccentric block thereof and a sound-controlled circuit which is composed of a buzzer and a triode VT < 1 > which are connected, and the sound-controlled circuit is connected with the music integrated circuit; the output of the music integrated circuit is connected with a triode VT < 2 > and a motor power supply to form a motor control circuit, the output of the music integrated circuit is connected with a triode VT < 3 > and a loudspeaker to form the circuit board of an amplification circuit. When people claps, the sound drives the sound-controlled circuit by the buzzer to make the music bell play music, and simultaneously, the motor power supply is switched on to drive the music bell to rock.

Description

Acoustic control rock music bell

The utility model relates to a kind of acoustic control rock music bell that integrates ornament, ornaments, toy.

Raising along with people's living standard, various deft designs, moving, the meeting singing of meeting, promptly making toy can make the decoration object depth that ornaments use again and be subjected to people's favor, number of patent application 96208242.2 " vibration type music bell " a kind of function singleness, only the music bell that can sing only be provided.

The purpose of this utility model is to provide a kind of use, control conveniently, multi-functional acoustic control rock music bell.

The utility model is achieved in that acoustic control rock music bell is made up of the power supply, buzzing sheet, music integrated circuit and the power switch that are installed in bell shell, the base plate, also have on the base plate a. bell clapper, motor and on the rock and roll device formed of eccentric block.B. have by buzzer and triode VT ₁The sound control circuit that connects and composes also is connected with music integrated circuit, music integrated circuit one tunnel output and triode VT ₂, motor power connects and composes circuit for controlling motor, music integrated circuit another road output and triode VT ₃, loudspeaker connects and composes the wiring board of amplifying circuit.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

There is a vocal hole on the top of bell shell (1), and 4 bar shaped vocal holes of two place's symmetries are arranged on the sidewall, and the fixed leg of three band screws is arranged on the inwall.

Uniform three discs of protruding through holes and breach, switch hole are arranged on being at the bottom of base plate (10), be groove in the middle of the lower surface, three fixed mounts (9) that the upper surface mid portion has vertically, there is open slot the centre and be with two fixed legs and the motor cabinet of screw.

Place two batteries (8) and battery cover (14) in base plate (10) the lower surface intermediate groove, place buzzer (6), loudspeaker (13), wiring board (11) in upper surface three fixed mounts (9) respectively.

Buzzer (6) one ends and triode VT ₁Emitter stage be connected with power switch (16), in addition end passes through resistance R ₁With with triode VT ₁The resistance R that colelctor electrode connects ₂Link to each other triode VT ₁Base stage and buzzer (6) and resistance R ₁Node connect and compose sound control circuit and be connected with music integrated circuit IC.

Music integrated circuit IC output, the one tunnel meets triode VT ₂Base stage, emitter stage connect power switch (16) and another output, positive pole, motor (5) power cathode that colelctor electrode connects motor (5) power supply connects battery (8) negative pole and another output constitutes circuit for controlling motor.

Another road of music integrated circuit IC output meets triode VT ₁Base stage, colelctor electrode by loudspeaker (13) and power switch (16), capacitor C ₁Join emitter stage and battery (8) negative pole, capacitor C ₁Link to each other the node of colelctor electrode and loudspeaker (13) and triode VT ₁Be connected with resistance R between base stage ₃And capacitor C ₂Constitute amplifying circuit, above-mentioned each circuit is fixedly connected on the wiring board (11).

Motor (5) one end faces are fixed on the motor cabinet of base plate (10), motor (5) axle passes pressing plate (4) and is connected with centrifugal (2), and pressing plate (4) is screwed on two fixed legs of base plate (10), and the switch base (12) of charged source switch (16) is fixed on base plate (10) the switch hole two edges.

Battery cover (14) upper surface both sides have seam and U type to buckle, and it is cylinder that lower surface has an end, and an end is hemispheroidal bell clapper (15).Battery cover (14) is buckled in the groove and breach of base plate (10) with seam on it and the fastening of U type, and the base plate (10) that assembles is screwed on the fixed leg of bell shell (1) lower end inwall, and the music bell is assembled into.

Centrifugal iron (3) tightly is enclosed within the interior integrant eccentric block of circular hole of centrifugal (2) one end.

Triode VT ₁, VT ₂Be 9012, VT ₃Be 9013.

During use, as long as power turn-on switch (16), have gentle hands light one is clapped, and sound is by the sound control circuit on sensor buzzer (6) the promotion wiring board (11), trigger triode VT ₁, making its conducting, then music integrated circuit IC work is through amplifying circuit VT ₃Triode amplifies, and plays out the sound of a first song or simulated animal by loudspeaker (13), makes triode VT through circuit for controlling motor simultaneously ₂Conducting is rotated thereby connect motor (5) power drives motor (5), and motor (5) rotates and just drives connected eccentric block and rotate, and makes whole music bell begin rock and roll under the effect of bell clapper (15), and when musical performance finishes, bell also stops rock and roll.If need repeat work, can clap with have gentle hands light one once more, trigger sound control circuit once more, the music bell is just played song and rock and roll once more.If will stop to play song halfway, as long as at this moment turn on the power switch (16), non-transformer, music bell just stop to play song and rock and roll at once.

The utility model is compared with prior art: this bell is used the Sound control acoustic control as long as clap with have gentle hands Circuit just makes musical bell play song. Simultaneously again therefore musical bell have by on the eccentric block and base plate on the motor The rock and roll device that forms of bell clapper, just make after the bell energising automatically rock and roll, use, control is convenient, no Only can play song and also can increase interest by rock and roll.
