[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] With the change of people's needs, the recording device is developing rapidly towards portability and miniaturization. At the same time, color displays and matrix microphones are gradually applied to mid- to high-end intelligent recording device products to improve the user's interaction experience and enhance the recording effect of the intelligent recording device. All these changes make the space and structure inside the recording device quite compact and complex. Therefore, it is difficult to compactly and effectively fix the battery and speaker in the recording device above the PCB board.

[0030] In order to solve the problem that it is difficult to compactly and effectively fix the battery and the speaker in the recording device above the PCB board in the prior art, the present invention specifically proposes a fixing structure for the recording device. The fixing structure includes: a speaker fixing member 1, a front sound cavity 13 is provided on the speaker fixing member 1 and is connected to the battery fixing member 2, and the speaker fixing member 1 and the battery fixing member 2 are located on the same side of the PCB board 4.

[0031] Therefore, the speaker and the battery in the recording device can be respectively fixed in the speaker fixing member and the battery fixing member, and then the speaker fixing member and the battery fixing member are integrally placed on the same side of the PCB board. Therefore, this fixing structure can limit the battery and the speaker on the same side of the PCB board at the same time, without wasting or occupying too much internal space, and perfectly solves the problem that it is difficult to effectively fix the battery and the speaker above the PCB board due to the complex and compact internal space of the recording device. Moreover, when the speaker or the battery fails, the structure can be disassembled for easy maintenance.

[0032] The principle and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0033] As Figure 1As shown in the figure, specifically, the speaker fixing member is composed of a first mounting plate and a fixing component connecting the battery fixing member. The first mounting plate is square, the width of the first mounting plate is equal to or slightly larger than the width of the speaker, and the length of the first mounting plate is equal to or slightly larger than the width of the battery. On the mounting surface of the first mounting plate, there is a square speaker mounting groove 11 for placing the speaker, so the shape and size of the speaker mounting groove are adapted to those of the speaker. When the speaker is placed in the speaker mounting groove, a cover plate 12 is fixed at the opening of the speaker mounting groove 11 to prevent the speaker in the speaker mounting groove from being damaged. At the same time, there is an open front sound cavity 13 below the speaker mounting groove 11, and the front sound cavity 13 is communicated with the speaker mounting groove 11. Only in this way can the sound of the speaker be transmitted from the front sound cavity, and the opening of the front sound cavity is arranged on the side surface of the first mounting plate. In order to enable the speaker fixing member to be tightly connected to the battery fixing member, the fixing component is the first fixing strip 14 and the second fixing strip 15 which are identical in shape and size and are arranged on the first mounting plate. The first fixing strip 14 and the second fixing strip 15 are arranged on two opposite side surfaces of the first mounting plate. The first fixing strip and the second fixing strip are in opposite positions, parallel to each other and in the same plane as the first mounting plate. Considering the function of the front sound cavity, when designing the first fixing strip and the second fixing strip, the front sound cavity is clamped between them, and the opening direction of the front sound cavity 13 is opposite to the extending direction of the first fixing strip 14 and the second fixing strip 15. Multiple mounting holes 16 are arranged at intervals on the first fixing strip and the second fixing strip, and there are grooves at the positions where the mounting holes 16 are arranged to facilitate the quick positioning of the battery fixing member 2 to the mounting holes. Screws pass through the battery fixing member 2, the mounting holes 16 and the speaker fixing member 1 for connection, and the lengths of the first fixing strip and the second fixing strip are less than or equal to the length of the battery fixing member.

[0034] Specifically, the battery fixing member 2 is a second mounting plate that is bent downward to form a battery mounting groove 21. The second mounting plate is square and as thin as possible. The four sides are bent to the same side until they are perpendicular to the second mounting plate, thus forming a square battery mounting groove. The battery is pasted to the bottom of the battery mounting groove with heat-resistant glue. On the opposite side edges of the second mounting plate, there are multiple feet 22 corresponding to the mounting holes 16 on the first fixing strip and the second fixing strip. Specifically, the extra space is dug on the bent edge to let the L-shaped feet 22 be arranged at the edge of the bottom of the battery mounting groove 21, and the feet 22 are arranged in the direction extending from the bottom of the battery mounting groove to the opening of the battery mounting groove. The height of the feet 22 is greater than the depth of the battery mounting groove 21 so that there is a gap between the battery at the bottom of the battery mounting groove and the PCB board 4. And on the edge of the bent sides of the other two sides of the second mounting plate, there are extension folded edges that are integrally connected perpendicular to the bent sides. One extension folded edge is buckled on the bottom surface of the speaker fixing member, and the other extension folded edge is pressed by the third fixing strip 3. The third fixing strip is provided with multiple mounting holes and is on the same side of the PCB board as the battery fixing member.

[0035] Therefore, after the speaker is installed on the speaker fixing member and the battery is installed on the battery fixing member, one extended folded edge of the battery fixing member is buckled on the bottom surface of the speaker fixing member, and the feet on the battery fixing member should correspond to the mounting holes on the first fixing strip and the second fixing strip. At the same time, the third fixing strip presses the other extended folded edge, and then the whole is placed above the front side of the PCB board. In order to protect the PCB board and facilitate fixation, the PCB board 4 is fixed on the aluminum plate 5. Threaded holes corresponding to the mounting holes are provided at the edge of the aluminum plate. Therefore, screws pass through the mounting holes on the first fixing strip, the second fixing strip, the third fixing strip and the threaded holes on the aluminum plate to fix the fixing structure on the aluminum plate. There is a gap between the PCB board and the battery between the fixing structure and the aluminum plate for heat dissipation. It can be seen that the designs of the speaker fixing member and the battery fixing member avoid the interference of other components, and the gap between the two is very small and the fit is very compact, maximizing the utilization rate of the internal space of the recording device.

[0036] In other embodiments, the sizes of the speaker fixing member and the battery fixing member are designed according to the sizes of the battery and the speaker in the recording device, and the length and width of the sizes are not fixed either. The overall effect needs to be considered for the design. And in this embodiment, the first fixing strip and the second fixing strip are integral with the first mounting plate. In other embodiments, they can be independently assembled together, and the fixing method of the battery is not limited to pasting.

[0037] The present invention also provides a recording device using this fixing structure to fix the internal speaker and battery. The recording device can be a recording pen.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
