Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, a bluetooth sound box comprises a box body 1 and an integrated circuit board 2 installed in the box body 1, wherein the integrated circuit board 2 is provided with a sound generating unit 20 and a signal receiving unit, the signal receiving unit is used for receiving bluetooth signals of a mobile phone, and the bluetooth sound box further comprises a sound transmission mechanism 3 and a horn 4; the sound transmission mechanism 3 and the horn 4 are both installed inside the box body 1, a sound transmission cavity channel 30 used for lengthening a sound transmission path is arranged in the sound transmission mechanism 3, the sound transmission cavity channel 30 is arranged in a multilayer spiral winding mode, one end of the sound transmission cavity channel 30 is connected with the sound production unit 20, the other end of the sound transmission cavity channel is connected with a sound inlet of the horn 4, a sound outlet of the horn 4 is installed at one end of the box body 1, and an opening is formed in one end, where the sound outlet of the horn 4 is installed, of the box body 1.

Specifically, the existing bluetooth speaker generally adopts a high-power speaker to enlarge the sound and sound effect of the playing, but increases the power consumption, so that the cruising ability of the bluetooth speaker is reduced. The embodiment of the utility model provides an in, integrated circuit board 2 is by the battery power supply, and the signal receiving unit on the integrated circuit board 2 receives the bluetooth information that comes from the cell-phone to through sound generating unit 20, play corresponding sound. The sound emitted from the sound emitting unit 20 is transmitted to the sound inlet of the horn 4 through the sound transmission channel 30 in the sound transmission mechanism 3, and then emitted from the sound outlet of the horn 4. Wherein, the longer the length of the sound transmission cavity channel 30, the longer the sound transmission stroke, the lower the sound frequency emitted by the horn 4, i.e. the better the bass effect; and then the sound amplification effect of the horn 4 can greatly increase the volume of the played sound and reduce distortion. Through the above-mentioned public address effect, the embodiment of the utility model discloses a can adopt than the loudspeaker vocal ware of normal bluetooth speaker less than power, send volume and the audio close with normal bluetooth speaker, can reduce bluetooth speaker's power consumption effectively, increase duration.

Further, the sound transmission mechanism 3 is a tubular structure, and an inner cavity of the tubular structure forms a sound transmission channel 30. The tubular structure can fulfill corresponding functions with a minimum of consumables and is more lightweight.

Further, the sound transmission mechanism 3 is a plate-shaped, block-shaped, columnar or spherical entity, a sound transmission groove is arranged in the entity, and the sound transmission groove forms a sound transmission cavity channel 30. The sound transmission groove arranged in the solid structure is used for transmitting sound, so that the sound loss caused by the vibration of the wall surface of the sound transmission groove when the sound is transmitted in the sound transmission cavity channel 30 can be reduced.

Further, the sound transmission channel 30 is spirally disposed. The spiral arrangement of the sound transmission cavity channel 30 can select longer cavity channel length, so that the played sound effect is better, and the sound transmission cavity channel is suitable for a Bluetooth sound box with larger volume.

Further, the sound transmission channel 30 is arranged in a vortex shape. Under the same space occupation ratio of the sound transmission mechanism 3, the space utilization rate of the vortex sound transmission cavity channel 30 is higher, and the device is suitable for the Bluetooth sound box with smaller volume.

Furthermore, a positioning boss 40 is arranged at the outer side of the sound outlet of the horn 4, a positioning groove 10 is arranged at the opening of the box body 1, and the positioning boss 40 is clamped into the positioning groove 10. Through location boss 40 and constant head tank 10, can be convenient for the installation location of horn 4 to when bluetooth speaker is vertical to be placed, bear horn 4 and the transaudient weight of 3 of being connected with horn 4, reduce transaudient degree of 3 rocking.

Further, the sound transmission channel 30 has a closed structure at one end connected to the sound generating unit 20 and is further provided with a funnel-shaped structure to form a pressure chamber. The sound unit 20 vibrates air while generating sound, and then moves and squeezes the air, so that the squeezed air passes through a channel with a smaller sectional area, and the air flow rate is increased, thereby increasing the sound radiation impedance of the sound and reducing the distortion of the sound unit 20.

Further, the sound transmission channel 30 has a sectional area gradually increasing with an increase in the transmission stroke from a side close to the sound generating unit 20 to a side close to the horn 4. The sound transmission channel 30 is equivalent to another horn to further amplify the sound.
