When a wired microphone is in use, the range in which it can be held and moved is usually limited to the length of the signal transmission line connected to it, and in use, it often causes a lot of inconvenience due to the winding of the signal transmission line. The wireless microphone is a benefit microphone developed to solve the shortcomings of the wired microphone described above. The small dry battery installed in the microphone and the design of the wireless signal transmission circuit make the wireless microphone have a wide range of movement and will not There is a problem with the signal cable being twisted. And because wireless microphones are widely available and convenient, they have gradually replaced the use of wired microphones. Because the handheld wireless microphone no longer has the problem of entangled signal cables, it is relatively free to use, so many singers or performers mostly use wireless microphones. Generally, a battery provided on a battery holder of a wireless microphone is generally provided with a metal piece disposed on two opposite ends of the battery holder for conducting electricity and a compression spring facing the two opposite ends of the battery. The limit is fixed on the battery holder, and a battery cover, 20 200537963, is placed on the battery holder to prevent the battery from falling out of the microphone. However, in fact, because there is a gap between the battery cover and the battery on the battery holder, and the battery cover usually does not have other components that directly or indirectly interfere with the battery, most of the conventional battery cover designs Only 5 * has the function of preventing the battery from falling out of the microphone, but does not have the function of fixing the battery limit on the battery holder. Therefore, when the microphone is shaken greatly during use, since the battery does not have any lateral support points on one side of the battery cover, it often happens that the battery is in the gap between the battery and the battery cover because the microphone is shaken too much. Partially, the battery and the battery holder or the battery and the battery have poor electrical contact, which makes the microphone signal suddenly disappear, so it often brings a lot of unnecessary trouble to the speakers, singers and listeners. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a microphone capable of stably positioning a battery 15 on a battery holder. Therefore, the microphone with a battery cover of the present invention is suitable for use with at least one battery, and includes an upright holding tube with a forward-facing opening, a battery holder fixed in the holding tube, and a cover provided in the holding tube. And cover the battery cover of the opening. 20 The front side of the battery holder is formed with an opening that extends up and down and has an opening facing the grip tube and is used to place the battery. The battery cover includes a cover body detachably disposed on the grip tube and covering the opening, and an elastic piece fixed on the inner side of the cover body and capable of elastically pressing against the front side of the battery. The effect of the present invention is that the battery cover's shrapnel can be pushed back against the front side of the 200537963 battery, so that the battery can be stably limited to the battery holder. [Embodiment] The foregoing and other technologies related to the present invention The content, features, and effects will be clearly understood in the detailed description of a preferred embodiment with reference to the accompanying drawings below 5. As shown in Figures 1, 2, and 3, the preferred embodiment of the microphone of the present invention is suitable for use with two cylindrical dry batteries 2 connected in series up and down. The microphone includes an upright grip tube 3 with a forward-facing opening 31, a circuit substrate 4 and a battery that are stacked up and down and are electrically connected to each other at the opening 31 of the grip tube 3. A base 5, a sound head 6 screwed on the top of the grip tube 3 and electrically connected to the circuit substrate 4, and a battery cover 7 detachably disposed on the grip tube 3 and covering the opening 31. The inner peripheral surface of the grip tube 3 is adjacent to the left and right edges 15 of the opening 31, respectively, forming abutting ribs 32 protruding opposite to each other, and the edge adjacent to the top of the opening 31 is formed with a protruding edge 33 protruding backward. The circuit board 4 can process the audio signal received by the audio head 6 and then wirelessly transmit it to the corresponding receiver (not shown in the figure), because this part is a frequently used wireless transmission technology And it is not the focus of the improvement of the present invention 20 'will not be described in detail here. The cross section of the battery holder 5 is a semi-circular arc shape, and a front side surface is formed with a receiving groove 51 extending upwardly and downwardly and opening forward, and the lower half of the receiving groove 51 is exposed to the grip tube 3 correspondingly. The opening 31 can be used for accommodating the two batteries 2 above and below in series. Most of the batteries 2 above are enclosed by the 200537963 holding tube 3, and only a small section is exposed through the opening 31. The lower battery 2 can be completely exposed through the opening 31. The battery 盍 7 can be surrounded by the battery holder 5 and pressed against the electricity; also 2I, the rear side, and includes-the cover body 71, which is arc-shaped in cross section, and The two sides 72 of the rear side of the cover body 71 protruding toward the battery holder 5, two positioning walls 73 protruding from the end edges of the bottom ends of the side walls 72 toward the left and right sides, and one protruding from the cover The engaging piece 74 at the top of the body 71 and the elastic piece 75 fixed on the rear side of the cover body 71 and located between the two side walls 15 and 72. The side walls 72 cooperate with the positioning walls on the same side to define two sliding grooves 76 which can be inserted by the two abutting ribs 32 of the gripping tube 3, respectively. The cover body 71 detachably covers the opening 31 of the gripping tube 3, and the cover body is formed on the upper and lower ends of the cover body with a pressing portion 711 that can be elastically pressed backwards, and two spaced protruding pillars protruding backwards. 712. The latching piece 74 protrudes from the top of the pressing portion 711 and has a limiting edge 741 protruding from the front side of the end portion. The integral clamping piece M can be extended into the grip tube 3 through the opening 31 of the grip tube 3 in a bottom-up manner, so that the bottom surface of the edge limiting edge 741 is locked against the top surface of the flange 汩. . The elastic piece 75 has a base plate 75 fixed to the cover body 71 and having an arc-shaped cross section, and a flat plate-shaped elastic arm portion 752 protruding from the top of the base plate 751 and extending rearward and upward. The elastic arm The rear side end of the portion 752 forms a top abutment edge 753 protruding rearwardly. The base plate 751 has two joint holes W two joint holes 754 corresponding to the projections 712 which are fitted on the cover body 71, and can be used to position the projections 712 by using an ultrasonic fusion machine or by heat fusion if necessary. Welding is performed to bond the substrate 751 and the two protrusions 712 together. The combination of the battery cover 7 and the grip tube 3 is to firstly rest the left and right edges of the rear side of the cover body 71 of the battery cover 7 on the two abutment ribs 32 of the grip tube 3 at this time. At this time, the battery cover 7 The two side walls 72 are respectively located on the facing surfaces of the two abutting ribs, and then the cover body 71 is pushed upward so that the cover body 71 gradually covers the opening 31, until the limit edge 741 of the locking piece at the top end of the cover body 7 j. Slightly elastically pushed past the rear side of the protruding edge of the grip tube 3, and then reset the spring, so that the bottom surface of the limiting edge 741 buckled against the top surface of the protruding edge. During the cover body 71 is pushed upward and snapped in position, the two sliding grooves 76 ′ formed between the two side walls 72 and the positioning wall 73 are respectively sleeved with the abutment ribs 32 of the grip tube 3 to make the cover body 71 is stably covered on the grip tube 3, and the elastic piece 75, which is simultaneously fixed to the rear side of the cover body 71, is elastically pressed against the upper half of the front side of the lower battery 2 by the top abutment edge 753 of the elastic arm portion 752 , And the battery 2 is stably limited to the battery holder 5. It is worth mentioning that in this embodiment, the battery holder 5 can accommodate two batteries 2 as an example, and the front side of the battery 2 located above is mostly surrounded by the grip tube 3. Therefore, it is easy to sigh 50% into a more constricted shape by holding the tube 3 upright, or presetting most protruding ribs 34 on the tube wall to abut the surrounding of the battery 2, so that the upper battery 2 has a better Effect However, the front side of the battery 2 located below is completely exposed in the range of the opening 31 of the grip tube 3, so it is necessary to strengthen the positioning effect. Therefore, in this embodiment, only the elastic piece 75 of the battery cover 7 is used to press against the The front side of the battery 2 below, but it is not limited to this in practice. For example, the length of the spring piece 75 200537963 degrees can be appropriately extended, and two spring pieces 75 are set at different heights to press the two batteries 2 separately, or The length of the elastic arm portion 752 of the elastic piece 75 can be appropriately extended so as to form two spaced-abutment, 彖 753 at different heights of the elastic arm portion 752, and it can also abut against the front side of the two batteries at the same time, so as to raise all the batteries. 2 positioning effect. When the two batteries 2 are to be removed, the front side of the pressing portion 711 of the cover body 71 is pressed to displace the pressing portion 711 backward, and then the latching piece 74 is displaced backward to cause the limiting edge 741 and the grip The flanges of the tubes 3 are separated, and then the cover body 71 can slide down along the abutting ribs 32 of the grip tube 3 to disengage the grip tube 3, and the batteries 2 can be removed or replaced at this time. Based on the design of the battery cover 7 attached with the elastic piece 75, the gap between the battery and the battery cover of the conventional microphone can be indirectly caused by the elastic arm portion 752 of the elastic piece 75 extending against the front side of the lower battery 2. The removal of the battery cover 7 allows the batteries 2 to be firmly located on the battery holder 5 5, thereby preventing the battery 2 from causing poor electrical contact between the battery and the battery holder during the microphone shaking process. To achieve the purpose of invention. However, the above-mentioned one is only a preferred embodiment of the present invention. If not, the scope of implementation of the present invention is not limited by this, that is, the simple equivalent changes made according to the scope of patent application of the present invention and the contents of the description of the invention. Modifications, 0 should still fall within the scope of the invention patent.
