Description

Technical Field

[0001] The utility model relates to the technical field of audio playing devices, and particularly provides a headphone storage box and an audio playing device. Background Art

[0002] True Wireless Stereo (TWS) headphones have become the mainstream products in current consumer audio playing products. TWS headphones are generally used with a headphone storage box, and the headphone storage box is used to store the headphones and charge the headphones.

[0003] Existing headphone storage boxes generally adopt a flip-type structure, that is, including a box body and a box cover, the box cover is hinged to the box body, and a storage groove for accommodating the headphones is arranged in the box body. When the headphones need to be taken out of the headphone storage box, first the box cover needs to be opened to expose the headphones, and then the headphones are taken out by hand. However, TWS headphones are small in size, and their outer shells are generally made of plastic. And in order to improve the wearing comfort, the surface of the outer shell is relatively smooth. Most of the outer shell of the headphones is accommodated in the storage groove, and only a small part is exposed. When taking out the headphones, the box cover will block the fingers, making it difficult for the fingers to grasp the headphones. Moreover, the contact area between the fingers and the headphones is small, and the fingers are prone to secrete oil, so it is easy to slip between the fingers and the headphones, and it is not easy to take out the headphones.

[0004] Therefore, a lidless headphone storage box has emerged. Existing lidless headphone storage boxes include an outer shell and an inner shell. The inner shell is used to carry TWS headphones, and the inner shell slides in the outer shell. In order to make the positions of the outer shell and the inner shell relatively fixed, a limiting mechanism for preventing the inner shell from detaching from the outer shell is arranged between the outer shell and the inner shell. The limiting mechanism generally includes a positioning hole arranged on the outer shell and a positioning key movably arranged on the inner shell. When the inner shell slides relative to the outer shell so that the positioning key is inserted into the positioning hole, the positioning between the inner shell and the outer shell is completed, and the inner shell can be prevented from detaching from the outer shell. The structure of this kind of limiting mechanism is relatively complex and prone to mechanical failures such as jamming, that is, the inner shell and the outer shell cannot slide, resulting in relatively low working reliability of the headphone storage box. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a headphone storage box and an audio playing device, aiming to solve the problem of relatively low working reliability of existing headphone storage boxes.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows: In the first aspect, the present application provides a headphone storage box, which includes an outer housing and an inner housing accommodated in the accommodation cavity of the outer housing. The inner housing is provided with an accommodation groove for accommodating the headphones. The inner housing is slidably disposed in the accommodation cavity so that the opening of the accommodation groove approaches or moves away from the opening of the outer housing. A blocking portion is provided at the opening of the outer housing for restricting the inner housing from detaching from the outer housing.

[0007] As a possible implementation manner, the blocking portion is formed by the inward extension of the outer housing, and a part of the positive projection of the blocking portion and the inner housing along the sliding direction of the inner housing overlaps.

[0008] As a possible implementation manner, the blocking portions are symmetrically arranged at the opening of the outer housing.

[0009] As a possible implementation manner, the outer housing includes a first outer housing and a second outer housing. The first outer housing and the second outer housing are connected and define the accommodation cavity. The blocking portion is provided on at least one of the first outer housing and the second outer housing.

[0010] As a possible implementation manner, an avoidance hole is provided on the side wall of the outer housing, and a pushing portion corresponding to the avoidance hole is provided on the inner housing. The pushing portion is used to move along the avoidance hole and drive the inner housing to slide relative to the outer housing.

[0011] As a possible implementation manner, when the inner housing and the blocking portion are in an interference state, one end of the inner housing close to the opening of the outer housing is located inside the outer housing.

[0012] As a possible implementation manner, a guiding structure is provided between the inner housing and the outer housing for guiding the inner housing.

[0013] As a possible implementation manner, the guiding structure includes a guide groove extending along the sliding direction of the inner housing provided on the inner housing and a guide rail provided on the outer housing and slidably engaged with the guide groove;

[0014] Alternatively, the guiding structure includes a guide rail extending along the sliding direction of the inner housing provided on the inner housing and a guide groove provided on the outer housing and slidably engaged with the guide rail.

[0015] In the second aspect, the present application provides an audio playback device, which includes headphones, a circuit component for electrically connecting with the headphones, and the aforementioned headphone storage box. The headphones are accommodated in the accommodation groove and slidably engaged with the accommodation groove. A circuit accommodation cavity for accommodating the circuit component is further provided on the inner housing or the outer housing.

[0016] As a possible implementation manner, a charging interface and / or a key electrically connected to the circuit component are provided on the side wall or the bottom wall of the inner housing facing the outer housing.

[0017] Advantages of the present utility model: An earphone storage box provided in the first aspect of the present utility model, compared with the existing earphone storage box without a cover, the blocking portion provided at the opening of the outer housing is exposed on the outer housing. The blocking portion can block the continuous sliding of the inner housing, thereby limiting the stroke of the inner housing and preventing the inner housing from detaching from the outer housing, replacing the existing limiting structure. The blocking portion has a simple structure and is not located between the inner housing and the outer housing, which can effectively avoid jamming between the inner housing and the outer housing due to the failure of the limiting structure, and improves the working reliability of the earphone storage box.

[0018] An audio playback device provided in the second aspect of the present utility model includes an earphone, a circuit component for electrically connecting to the earphone, and the aforementioned earphone storage box. The earphone is accommodated in the accommodation groove and is in sliding fit with the accommodation groove. A circuit accommodation cavity for accommodating the circuit component is further provided on the inner housing and / or the outer housing. Since the aforementioned earphone storage box has higher working reliability, the audio playback device provided by the present utility model including the aforementioned earphone storage box also has higher working reliability.

[0029] Please refer to Figure 1 and Figure 2, a headphone storage box provided by the present application includes an outer housing 100 and an inner housing 200 accommodated in the accommodation cavity of the outer housing 100. The inner housing 200 is provided with an accommodation groove 202 for accommodating the headphones. The inner housing 200 is slidably disposed in the accommodation cavity so that the opening of the accommodation groove 202 approaches or moves away from the opening of the outer housing 100. A blocking portion 102 for restricting the inner housing 200 from detaching from the outer housing 100 is provided at the opening of the outer housing 100. The blocking portion 102 may be a structure integrally formed with the outer housing 100, such as a protrusion extending from the outer housing 100, or a structure connected to the outer housing 100, such as a block adhered or screwed to the outer housing 100. When the blocking portion 102 interferes with the inner housing 200, it can block the movement of the inner housing 200, thereby preventing the inner housing 200 from detaching from the outer housing 100. The blocking portion 102 may interfere with one end of the inner housing 200 where the accommodation groove 202 is provided; the blocking portion 102 may also interfere with the side wall of the inner housing 200. For example, a step is provided on the side wall of the inner housing 200, and the step interferes with the blocking portion 102; the blocking portion 102 may also interfere with the other end of the inner housing 200. For example, a protrusion protruding from the side wall of the inner housing 200 is provided at the other end of the inner housing 200, and the blocking portion 102 interferes with the protrusion.

[0030] The headphone storage box can be used to store headphones. After adding a circuit component to the headphone storage box, it can be used to charge the headphones while storing the headphones. The headphone storage box includes an outer housing 100 with an opening and an inner housing 200 accommodated in the outer housing. The inner housing 200 is provided with an accommodation groove 202 for accommodating the headphones. The shape of the accommodation groove 202 is adapted to the headphones to be accommodated. An avoidance hole 101 is provided on the side wall of the outer housing 100, and a pushing portion 201 corresponding to the avoidance hole 101 is provided on the inner housing 200. The pushing portion 201 is used to move along the avoidance hole 101 and drive the inner housing 200 to slide into and out of the outer housing 100 through the opening. As a possible example, the pushing portion 201 may be a pin provided on the inner housing 200 and extending in the same direction as the sliding direction of the inner housing 200. The avoidance hole 101 may be provided on the side wall of the outer housing 100 opposite to the outlet of the outer housing 100. The pin is in clearance fit with the avoidance hole 101; when it is necessary to take out the headphones, the inner housing 200 can be slid towards the opening of the outer housing 100 by pushing the pin. When the inner housing 200 contacts the blocking portion 102 on the outer housing 100, the inner housing 200 cannot continue to move towards the direction closer to the outer housing 100, thereby preventing the inner housing 200 from detaching from the outer housing 100 due to excessive thrust.

[0031] When storing the earphone in the earphone storage box, the earphone can be placed in the receiving groove 202 of the inner housing 200 located in the outer housing 100. When the earphone needs to be taken out, a pushing force is applied to the pushing part by a finger, so that the pushing part moves along the avoidance hole 101, thereby driving the inner housing 200 to move, and then sliding the inner housing 200 towards the opening of the outer housing 100. The opening of the receiving groove 202 can extend out of the outer housing 100. For example, the inner housing 200 can extend out 1 / 3 of its length from the opening of the outer housing 100, or be parallel to the opening of the outer housing 100, or be located inside the outer housing 100, as long as the earphone in the receiving groove 202 is exposed from the opening of the outer housing 100. The dimensional relationship between the earphone and the receiving groove 202 can be defined according to specific requirements.

[0032] When taking the earphone, the lid of the existing flip - type earphone storage box will block the bending of the finger. Moreover, the earphone is generally connected to the earphone storage box by magnetic attraction. The lid will prevent the user's finger from applying pressure to the earphone, resulting in a small frictional force between the finger and the earphone, which is not easy for the user to take the earphone. Also, after the lid and the box body are closed, the lid of the flip - type earphone storage box will block the user's line of sight. When the earphone is lost, the user is not easily aware that the earphone has been lost, resulting in the user not being able to discover and search for the lost situation in time. Therefore, an additional earphone needs to be purchased, bringing a high usage cost to the user.

[0033] As a possible embodiment, the earphone storage box can be without a lid. Compared with the existing flip - type earphone storage box, the earphone storage box without a lid has no structure that blocks the bending of the finger. After the inner housing 200 slides out of the outer housing 100, when taking the earphone from the receiving groove 202 of the earphone storage box, the receiving groove 202 extending out of the outer housing 100 is convenient for the finger to grab the earphone in the receiving groove 202. As a possible example, the earphone storage box can be used to store the earphone and charge the earphone. A circuit component and a charging indicator for charging the earphone are provided on the inner housing 200. The charging indicator can reflect the charging state of the earphone. When the earphone is stored in the receiving groove 202, it forms an electrical connection with the circuit component. The user can observe the charging state of the earphone in the receiving groove 202 of the inner housing 200, and can also conveniently observe whether the earphone placed in the receiving groove 202 is lost in time, so as to facilitate the user to search in time and increase the possibility of retrieving the lost earphone.

[0034] Please refer to Figure 1 and Figure 2, as a possible implementation, the blocking portion 102 is formed by extending inward from the outer housing 100, and the blocking portion 102 and the inner housing 200 overlap in the positive projection along the sliding direction of the inner housing 200. The blocking portion 102 and the outer housing 100 are integrally formed by injection molding or the like, so that the end of the inner housing 200 provided with the receiving groove 202 cannot extend out of the outer housing 100, ensuring that the inner housing 200 cannot be detached from the outer housing 100.

[0035] See Figure 1 and Figure 2 , as a possible implementation, the blocking portion 102 can be symmetrically arranged at the opening of the outer housing 100. The blocking portion 102 symmetrically arranged at the opening of the outer housing 100 can effectively prevent the inner housing 200 from detaching from the outer housing 100 and also prevent foreign objects from entering between the inner housing 200 and the outer housing 100. Exemplarily, the number of the blocking portions 102 can be two, and the two blocking portions 102 are symmetrically arranged at the opening of the outer housing 100 with respect to the extending direction of the opening of the outer housing 100. With such a design, the outer housing 100 is more aesthetically pleasing.

[0036] See Figure 1 and Figure 2 , as a possible implementation, the outer housing 100 includes a first outer housing and a second outer housing. The first outer housing and the second outer housing are connected and define a receiving cavity, and the blocking portion 102 is provided on at least one of the first outer housing and the second outer housing. The blocking portion 102 can be provided on the first housing, or the blocking portion can be provided on the second housing. The blocking portion 102 can also be provided on both the first housing and the second housing at the same time. By dividing the outer housing 100 into two connected parts, namely the first outer housing and the second outer housing, it is convenient to install the inner housing 200 into the outer housing 100 during production. Exemplarily, the inner housing 200 can be first installed into the first outer housing, and then the second outer housing can be connected to the first inner housing by bonding, snap connection or screwing.

[0037] See Figure 1 and Figure 2 , as a possible implementation, when the inner housing 200 and the blocking portion 102 are in an interference state, one end of the inner housing 200 close to the opening of the outer housing 100 is located inside the outer housing 100. With such a design, it can be ensured that the inner housing 200 does not extend out of the opening of the outer housing 100, making the earphone storage box more aesthetically pleasing.

[0038] As a possible implementation, in order to improve the stability of the inner housing 200 when sliding relative to the outer housing 100, such that the inner housing 200 is not prone to wobbling during sliding, to improve the fitting accuracy between the inner housing 200 and the outer housing 100, and to enhance the user experience, a guiding structure for guiding the inner housing 200 is provided between the inner housing 200 and the outer housing 100. The guiding structure can keep the trajectory of the inner housing 200 stable during the process of extending out of the outer housing 100, and is not prone to generating wobbling inconsistent with the sliding direction of the inner housing 200. The guiding structure can include, but is not limited to, a chute-slider guiding structure and a guide rod-guide hole guiding structure.

[0039] As a possible implementation, the guiding structure includes a guide groove provided on the inner housing 200 and extending along the sliding direction of the inner housing 200, and a guide rail provided on the outer housing 100 and slidably engaged with the guide groove.

[0040] Alternatively, the sliding guiding structure includes a guide rail provided on the inner housing 200 and extending along the sliding direction of the inner housing 200, and a guide groove provided on the outer housing 100 and slidably engaged with the guide rail.

[0041] Please refer to Figure 3 and Figure 4 and, on the other hand, the present application provides an audio playback device, including an earphone 300, a circuit component for electrically connecting with the earphone 300, and the aforementioned earphone storage box. Exemplarily, the circuit component can be used to charge the earphone; the earphone 300 is accommodated in the accommodation groove 202 and slidably engaged with the accommodation groove 202. As an example, the earphone 300 can form a temporary connection with the accommodation groove 202 by magnetic attraction to prevent the earphone 300 from slipping out of the accommodation groove 202. A circuit accommodation cavity 205 for accommodating the circuit component is further provided on the inner housing 200 or the outer housing 100. As a possible implementation, the circuit component can be disposed in the circuit accommodation cavity 205 on the outer housing 100, and a separable plug-in fit is formed between the inner housing 200 and the circuit component. During the process of the inner housing 200 approaching the outer housing 100, an electrical connection can be formed with the circuit component, and during the process of the inner housing 200 moving away from the outer housing 100, the electrical connection with the circuit component can be disconnected.

[0042] Compared with the flip - type earphone storage case, the audio playback device provided by the present application includes the aforementioned earphone storage case. Compared with the flip - type earphone case, the earphone storage case of the audio playback device provided by the present application has no lid and there is no structure that blocks the bending of fingers. When taking out the earphones 300 from the accommodation groove 202 of the earphone storage case, the accommodation groove 202 extending out of the outer housing 100 facilitates the fingers to grasp the earphones 300 in the accommodation groove 202, and it is also convenient to observe the charging status of the earphones 300 in the earphone storage case or whether they are lost. As a possible example, when the earphone storage case is used to store and charge the earphones, when a circuit component for charging the earphones and a charging indicator are provided on the inner housing 200, the charging status of the earphones located in the accommodation groove 202 of the inner housing 200 can be observed, and it is also convenient for the user to timely observe whether the earphones placed in the accommodation groove 202 are lost, so as to facilitate the user to search in time and increase the possibility of retrieving the lost earphones by the user.

[0043] As a possible implementation manner, a charging interface and / or a button electrically connected to the circuit component are provided on the side wall of the inner housing 200 facing the outer housing 100. As an example, a charging interface or a button can be provided on the inner housing 200, and both a charging interface and a button can also be provided on the inner housing 200 at the same time. The button can be a switch button. This implementation manner is beneficial to hiding the charging interface and the button when the inner housing 200 is stored in the outer housing 100, and improving the overall aesthetics of the audio playback device.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
