[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a handheld speaker.

[0040] Reference Figure 1 , Figure 2The handheld horn includes a horn body 1 and a housing 2 located on the lower side of the horn body 1. A positioning member 7 is installed at the upper end of the housing 2 to fix the horn body 1 and ensure the stability of the connection between the horn body 1 and the housing 2. The horn body 1 includes a horn tube 11 and a rear cover 12 connected to one end of the horn tube 11. A diaphragm (not shown in the attached drawings) is connected between the horn tube 11 and the rear cover 12. The diaphragm vibrates to produce sound, which is amplified by the horn tube 11. The rear cover 12 is connected to the upper end of the positioning member 7. An electric air pump 4 is installed at the upper end of the housing 2. One end of the electric air pump 4 is connected to a connecting seat 5. A vent 6 is connected between one end of the connecting seat 5 and the rear cover 12 to guide the gas generated by the electric air pump 4 to the rear cover 12 to vibrate the diaphragm. A control button 221 is located in the middle of the housing 2 to control the operation of the electric air pump 4. A battery 3 is located at the lower end of the housing 2 to provide power to drive the electric air pump 4.

[0041] Reference Figure 1 , Figure 2 The housing 2 includes a mounting portion 21 disposed on the lower side of the speaker body 1, a grip portion 22 fixedly connected to the lower side of the mounting portion 21, and a base 23 fixedly connected to the lower end of the grip portion 22. The inner wall of the mounting portion 21 has a mounting channel 211 for inserting the electric air pump 4. An air inlet 212 communicating with the mounting channel 211 is provided at one end of the mounting portion 21 near the positioning member 7 to ensure stable operation of the electric air pump 4. In this application, the air inlet 212 adopts a recessed design; in other embodiments, the air inlet 212 can also adopt a planar or inclined design.

[0042] Reference Figure 2 , Figure 4 and Figure 5 One end of the electric air pump 4 has a insertion slot 41, and the end of the connecting seat 5 near the electric air pump 4 has an insertion part 53 for inserting into the insertion slot 41, to ensure the stability of the connection between the electric air pump 4 and the connecting seat 5. A limiting part 52 is fixedly connected to the outer wall of the connecting seat 5, and one end of the mounting part 21 has an abutment part 215 connected to the limiting part 52, to prevent the connecting seat 5 from detaching from the mounting part 21. The upper end of the connecting seat 5 is connected to a positioning connector 51 connected to the venting component 6, and the connecting seat 5 has an inner cavity for guiding gas flow. The venting component 6 communicates with the inner cavity of the connecting seat 5 through the positioning connector 51. One side of the mounting part 21 has an opening slot 213 for inserting the positioning connector 51, for positioning and installing the connecting seat 5. One side of the mounting part 21 is connected to a sealing cover 8 for covering the connecting seat 5, to ensure the stability of the connection between the connecting seat 5 and the mounting part 21, and to prevent air leakage at the connecting seat 5.

[0043] Reference Figure 4The ventilation component 6 includes two sealing joints 61 and a ventilation pipe 62 connected between the two sealing joints 61. One sealing joint 61 is fixedly connected to the rear cover 12, and the other sealing joint 61 is fixedly connected to the positioning joint 51. This is to ensure that the high-pressure airflow generated by the electric air pump 4 can pass through the inner cavity of the connecting seat 5 and the ventilation pipe 62 and be introduced into the rear cover 12 without damage to drive the diaphragm to vibrate.

[0044] Reference Figure 2 , Figure 5 The positioning component 7 includes a positioning plate 71 disposed inside the mounting portion 21 and a mounting plate 72 connected to the rear cover 12. The inner wall of the mounting portion 21 has a slot 214 for inserting the mounting plate 72, at which point one side of the mounting plate 72 abuts against the inner wall of the mounting portion 21. Positioning holes 73 are provided at the corners of both the positioning plate 71 and the mounting plate 72 for fasteners to be inserted. The fasteners ensure the stability of the connection between the positioning plate 71 and the rear cover 12, and between the positioning plate 71 and the mounting plate 72.

[0045] In use, first, insert the mounting plate 72 into the slot 214 of the mounting part 21, so that one side of the mounting plate 72 abuts against the inner wall of the mounting part 21. Then, use a fastener to pass through the positioning hole 73 at the upper end of the positioning plate 71 and turn it into the back cover 12 to fix the positioning plate 71 to one side of the back cover 12. Next, attach the positioning plate 71 to one side of the mounting part 21 so that the positioning plate 71 is aligned with the positioning hole 73 of the mounting plate 72. Finally, tighten the fastener so that it passes through the positioning plate 71 and the side wall of the mounting part 21 and turns into the positioning hole 73 of the mounting plate 72 until the positioning plate 71 abuts against the side wall of the mounting part 21, thus completing the fixing of the speaker body 1.

[0046] Reference Figure 2 , Figure 3 and Figure 6 The lower end of the housing 2 has a limiting groove 231 for inserting the battery 3. A stationary contact 234 connected to the battery 3 is located inside the base 23, and an insertion port for inserting the stationary contact 234 is provided at the upper end of the battery 3. Guide rails 232 are fixedly connected to the inner walls of opposite sides of the limiting groove 231, and guide grooves 31 are provided on both sides of the battery 3 for inserting the guide rails 232, ensuring accurate installation of the battery 3. A latching component 32 is installed on one side of the battery 3; this latching component 32 is existing technology and will not be described further. A latching groove 233 is provided on the lower side of the housing 2 for the latching component 32 to hook onto, and the latching groove 233 communicates with the limiting groove 231 to prevent the battery 3 from accidentally detaching from the base 23.

[0047] When installing the battery 3, insert it into the limiting groove 231 and insert the guide rail 232 into the inner wall of the guide groove 31 until the buckle 32 hooks the buckle 233. At this time, the battery 3 is connected to the stationary contact 234 in the housing 2, and the installation of the battery 3 is completed.

[0048] The implementation principle of the handheld speaker in this application embodiment is as follows:

[0049] When in use, first install the battery 3 at the lower end of the housing 2. Then, hold the grip part 22 of the housing 2 and press the control button 221 to control the electric air pump 4 to run. The gas generated enters the rear cover 12 through the connecting seat 5 and the vent 6. Then the airflow enters between the horn 11 and the rear cover 12, driving the diaphragm to vibrate and produce sound. The sound is amplified and propagated through the horn 11.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
