Description

Technical Field

[0001] The utility model relates to the technical field of audio engineering, and particularly relates to a mobile phone two-in-one speaker. Background Art

[0002] As an electronic device, a mobile phone speaker is mainly used to convert electrical signals into sound, and its functions and significance lie in many aspects, including information transmission, entertainment experience, education, medical treatment and other fields. The speaker can improve the experience of remote communication, provide better sound quality and immersion, increase auditory enjoyment, and can also enhance the safety protection function and timely warn of dangers. Existing mobile phone speakers can basically meet the usage requirements of life, but there are still some deficiencies;

[0003] First of all, the speakers used in traditional mobile phones are divided into two parts: a receiver and a speaker. This design may lead to insufficient sound clarity in actual use. For example, the receiver is mainly responsible for the sound output when answering a call, while the speaker is used to play music or other audio content. This separate design may affect the overall quality of the sound, resulting in unsatisfactory clarity of voice or audio. Secondly, this traditional speaker design occupies the internal space of the mobile phone, making the overall structural design of the mobile phone more complex. Since corresponding spaces need to be reserved for the receiver and the speaker respectively, this not only limits the layout of other components, but may also increase the manufacturing cost of the mobile phone. In addition, the presence of multiple speaker components also makes the assembly and production process of the mobile phone more cumbersome, thus further increasing the cost;

[0004] Therefore, it is necessary to design a mobile phone two-in-one speaker. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mobile phone two-in-one speaker to solve the above-mentioned problems.

[0006] To solve the above technical problems, the utility model provides the following technical solution: A mobile phone two-in-one speaker, including a rear shell, a front shell, an electronic wire, a PCB and a magnet. The top of the rear shell is fixedly connected to the front shell by screws. An electronic wire is installed inside the rear shell. A receiving cavity is provided in the front shell. A support frame is sleeved in the receiving cavity, and a U cup is injection-molded in the support frame. A voice coil is sleeved in the U cup. A magnet and a washer are respectively sleeved inside the voice coil. A diaphragm is fixed on the support frame. A PCB is fixed on the support frame. The electronic wire is electrically connected to the PCB. A pressing edge is fixedly sleeved at the bottom of the support frame, and the pressing edge tightly presses on the diaphragm.

[0007] As a further technical solution of the utility model, a positioning block is fixedly connected to the rear shell.

[0008] As a further technical solution of the present utility model, mounting holes are provided on the rear shell.

[0009] As a further technical solution of the present utility model, a connecting block is fixedly connected to the rear shell.

[0010] As a further technical solution of the present utility model, positioning columns are provided on the rear shell, and the positioning columns are sleeved in through holes symmetrically provided on the front shell.

[0011] As a further technical solution of the present utility model, a clamping block is fixedly connected to the front shell, and a positioning hole is provided on the front shell.

[0012] As a further technical solution of the present utility model, a positioning protrusion is fixedly connected to the front shell, and a limiting block is fixedly connected to the front shell.

[0013] An integrated speaker for mobile phones provided by the present utility model has the following advantages: An electrical signal containing information such as the frequency and amplitude of sound is transmitted to the voice coil through the mobile phone. When the electrical signal flows through the voice coil, an electromagnetic force is generated in the magnetic field generated by the magnet. According to the change of the current, the voice coil generates forces in different directions in the magnetic field generated by the magnet. Due to the action of the electromagnetic force, the voice coil pushes the diaphragm to vibrate back and forth, forming sound waves, thereby integrating the structures of the earpiece and the speaker, increasing the clarity of audio or voice; at the same time, there is no need to reserve corresponding spaces for the earpiece and the speaker at the same time, reducing the occupation of the internal space of the mobile phone, simplifying the structure of the mobile phone, and reducing the cost.
