Detailed Description

Referring to fig. 1 and 2, an automatic lifting bluetooth speaker includes a housing 10, a main board 20, a high pitch system, a mid-low system, a radiator 60, and a battery 70.

The mainboard 20 is equipped with bluetooth module, and bluetooth module's quantity is one or two, and the mainboard is installed in shell 10.

With reference to fig. 3 and 4, the tweeter system is disposed within the housing 10 and includes a tweeter 40 and a tweeter 41, the tweeter being positioned above the tweeter. The top of shell is equipped with the opening, is equipped with frame 11 in the shell, and loudspeaker and sound awl are installed on crane 12, crane clearance fit is in the frame, is equipped with the drive crane edge in the shell the drive mechanism of frame lift, drive mechanism by the motor drive who sets up in the shell, the motor with mainboard connection. Preferably, the transmission mechanism is a gear rack mechanism, a rack 31 of the transmission mechanism is installed on the lifting frame 12, and a gear 32 of the transmission mechanism is installed on a motor shaft of the motor.

The periphery of crane 12 is equipped with limit flange 13, and high pitch cone 41 is located limit flange's top, and high pitch loudspeaker 40 is located limit flange's below, and the external diameter of high pitch cone is less than shell 10 open-top's internal diameter, and limit flange's external diameter is greater than shell open-top's internal diameter. Under the drive of the motor, the lifting frame 12 rises until the limit flange abuts against the edge of the top opening of the shell, the lifting frame stops rising, at the moment, the high-pitch cone 41 protrudes out of the top opening of the shell, and the high-pitch loudspeaker 40 is positioned in the shell. The sound emitted by the high pitch loudspeaker is upwards transmitted, and is downwards reflected or transversely reflected after passing through the high pitch cone 41, and the sound wave reflected downwards meets the sound wave transmitted upwards to resonate, so that the sound quality of the high pitch loudspeaker is improved; the sound waves reflected transversely are transmitted to the periphery of the sound box, so that the transmission range of the sound waves is enlarged, and listeners can enjoy music with the same tone quality and loudness at any position around the sound box.

As shown in fig. 2, the midbass system includes a midbass horn 50, a midbass cone 51 located above the midbass horn, and a midbass cone located below the tweeter 40. An independent sound cavity 14 is arranged in the shell 10, the midbass loudspeaker is arranged in the independent sound cavity, and a loudspeaker air-diffusing hole 52 is arranged on the shell 10 and is positioned around the midbass cone. The inner side wall of the shell 10 is provided with a first clapboard 16 and a second clapboard 17, the midbass cone 51 is arranged on the first clapboard, and the midbass loudspeaker 50 is arranged on the second clapboard. The independent sound cavity 14 can enable the sound emitted by the alto-bass loudspeaker 50 to vibrate in the independent sound cavity, so that a better alto-bass effect is realized; the sound emitted by the alto-bass loudspeaker is upwards transmitted, and is downwards reflected or transversely reflected after passing through an alto-bass cone 51, and the downwards reflected sound wave meets the upwards transmitted sound wave to resonate, so that the sounding quality of the alto-bass loudspeaker is improved; the sound waves reflected transversely are transmitted to the outside of the sound box through the loudspeaker air dispersing holes 52, so that the transmission range of the sound waves is improved, and listeners can enjoy music with the same tone quality and loudness at any position around the sound box.

As shown in fig. 2, the radiator 60 is disposed below the woofer 50, the casing 10 is provided with a radiator air-diffusing hole 61, the radiator air-diffusing hole is located below the radiator, a bottom casing 15 of the sound box is located below the radiator air-diffusing hole, and the bottom casing is mounted at the bottom of the casing 10. A third partition 18 is provided on the inner side wall of the housing 10, and the radiator 60 is mounted on the third partition. The sounding of the alto-woofer is downward spread, the radiator vibrates, the vibration of the radiator makes the air below the radiator vibrate to sound, and the sounding is spread around the sound box through the air-diffusing holes of the radiator. The tweeter and the alto-woofer are by the well woofer 51 is isolated from top to bottom, and the space of independent sound chamber 14 and radiator below is by the radiator is isolated, so, audio amplifier upper portion is the sound production of tweeter, and the audio amplifier middle part is the sound production of well woofer, and the audio amplifier lower part is the sound production of radiator, and the level of this audio amplifier sound production is distinct, and the high pitch, well bass are clear, certainly, and the joyful of appreciating can obtain promoting.

As shown in fig. 2, the battery 70 is located between the third partition 18 and the bottom case 15, and the battery is connected to the main board 20.

Be equipped with charging circuit, bluetooth module, power amplifier circuit, control circuit and button on the mainboard 20, charging circuit is connected with the battery, power amplifier circuit, bluetooth module, charging circuit and button are connected respectively to control circuit, power amplifier circuit connects loudspeaker, well woofer and motor. The bluetooth of smart mobile phone with bluetooth module pairs and connects, realizes the wireless connection of cell-phone and bluetooth speaker, and the cell-phone passes through wireless connection and conveys control signal to control circuit, and under control circuit's control, loudspeaker, well woofer and motor action realize the broadcast of audio amplifier sound and the lift of high pitch system. Patent document CN 107708026A discloses a bluetooth speaker which can connect two bluetooth speakers through a smart phone at the same time, and certainly, it can connect a bluetooth speaker and a motor through a smart phone at the same time.

Or, two independent control components are arranged on the motherboard 20, and each control component includes a charging circuit, a bluetooth module, a power amplifier circuit, and a control circuit. The two control parts are respectively a first control part and a second control part, the first control part is used for controlling a tweeter and a mid-bass loudspeaker in the sound box, and the second control part is used for controlling a motor in the sound box. The connection between the first control component and the mobile phone and the control of the first control component on the loudspeaker and the mid-bass loudspeaker adopt the Bluetooth technology in the prior art; the connection between the second control component and the mobile phone and the control of the motor by the second control component adopt a principle that the mobile phone controls the motor of the trolley in a remote control type trolley motor driving system (with an authorized bulletin number of CN 206441330U) based on Android and Bluetooth.
