Description

[Technical field]

[0001] The present invention relates to the field of earphone technology, and more particularly to a modular, replaceable housing earphone. [Background technology]

[0002] With the vigorous development of the wearable industry, earphones are becoming more and more diverse and specialized, and the China Industrial Research Institute predicts that the sales volume of earphones will reach more than 3 billion pairs in 2023. How to meet the needs of users for different scenes and appearances and give users a better experience is one of the keys to the success of products.

[0003] Currently, there are three main types of TWS earphones on the market: in-ear TWS earphones, inner-ear TWS earphones, and open-ear ear clips / hooks. Each type is suitable for different specialized scenes, and each has its own advantages and disadvantages, but none of them can meet all the needs of users. For example, in-ear TWS earphones have high acoustic effects, stable wearing, and significant noise reduction effect, but they are uncomfortable to wear and unhygienic. In-ear TWS earphones are obviously superior to in-ear TWS earphones in terms of wearing comfort, but their noise reduction effect is significantly inferior to in-ear TWS earphones. Secondly, inner-ear TWS earphones do not have earpieces, so they rely entirely on the front chamber of the earphone and cannot be adapted or adjusted to the ear of the person, and the wearing experience varies greatly from person to person. Open-ear ear clips / hooks have the best wearing comfort, but have no advantages compared to the two in other aspects. In addition, they are bulky and difficult to carry, and their appearance is not favorable, so they are rarely used in daily life scenes other than exercise.

[0004] As described above, different types of earphones each have their own focus for different usage scenarios, but none of them can cover all the usage scenarios and lifestyles of users. Many users need to purchase two to three different types of earphones to meet their needs, which increases additional economic expenditure. More users only use earphones in the scenarios that the products support, and do not use them at other times or have to endure them forcefully, thereby reducing the user's dependence on the products or generating a very bad usage experience. In addition, the structural parts of different types of earphones are difficult to remove, maintain, and repair. It is difficult to realize the mutual sharing of the structural parts of different types of earphones, and they need to be developed and produced individually, resulting in high production costs and low production efficiency.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Based on the deficiencies of the above prior art, the problem to be solved by the present invention is to provide an earphone with a modular housing that can be replaced. The earphone can be converted into different types of earphones, such as canal-type earphones, inner-ear-type earphones, open-ear-type earphones, etc., by replacing the housing. It provides a product that can be applied to multiple scenarios such as going out, office work, and exercise in a more economical way, thereby better meeting the diverse needs of users. The earphone can provide a case with a rich appearance and color, allowing users to have a wider selection space and better meet the individual needs of users. Users can select cases with different sizes and forms to fit the earphone to different ear canal structures, making the wearing more comfortable and stable. The earphone adopts a modular structure, and the modular structure method is easy to maintain and repair. The earphone changes the production method of conventional earphones, derives multiple products from one module, effectively shortens the development cycle, reduces production costs, and produces as many products as possible with as little input as possible.
