Description

Technical Field

[0001] The utility model relates to the technical field of waist-pack transmitters, in particular to a waist-pack transmitter with convenient battery replacement. Background Art

[0002] A belt-pack transmitter is a portable wireless communication device used to receive signals from a microphone transmitter. The microphone sends the sound signal to the receiver through the belt-pack wireless transmitter and amplifies it through the power amplifier to achieve sound amplification. At present, there are two ways to power the transmitter of a wireless microphone: charging and replacing the battery. Both have their advantages. Among them, rechargeable batteries can be reused, reducing the cost of use; while using replaceable batteries, although the cost of use is relatively high, it can be quickly replaced and is relatively convenient to use.

[0003] However, most of the current belt-pack transmitters that use replaceable batteries use a detachable battery cover to open or close the battery cavity for battery replacement. The battery cover of ordinary belt-pack transmitters on the market is generally opened by tilting the cover, that is, putting the thumb in the reverse direction into the concave arc of the semicircle to tilt the battery cover. This design has the following disadvantages:

[0004] 1. It is difficult to lift the battery cover when the user does not have fingernails; even if it is lifted with difficulty, it is easy to injure the thumb.

[0005] 2. If the tilting force of the battery cover is too great after long-term use, the fasteners of the battery cover may be easily broken.

[0006] In addition, the battery cells of ordinary battery covers on the market need to be fixed on the inner side of the battery cover with glue and nails. Firstly, its assembly requires manual dispensing of glue, which not only has low production efficiency and strong odor, but also because there is no positioning, the position accuracy of the battery cells is low during the manual patching process, and it is easy to be offset, resulting in poor contact between the battery cells and the battery; secondly, after long-term use, the glue is easy to oxidize, causing the battery cells to fall off easily, which in turn causes poor contact between the battery cells and the battery, affecting the use of the transmitter.

[0007] How to design a waist-pack transmitter that can quickly and easily open the battery cover and fix the battery cells without glue and nails has become a technical problem that urgently needs to be solved in this field. Summary of the invention
