What are the effects of a broken phone speaker?

Mobile phone speakers.

Damage will cause the speaker to be silent, murmuring, and squeaky.

If the speaker of the mobile phone is damaged, it is recommended that you:

2.If it doesn't work, please restart your phone and try.

Try. 4.If the problem persists, please bring the purchase invoice, repair card and machine to the Samsung after-sales service center for inspection.

If you are using a Huawei phone, we recommend that you back up the data in your phone in advance and bring the warranty certificate to a nearby Huawei Customer Service Center for repair

2. You can log in to Huawei's official website on your computer**, and click "After-sales outlets" to query the address at the bottom of the Huawei** page.

There are two ways to tell if your phone's speaker is broken:

1. Use the RX1 gear of the multimeter to connect the two meter pens to the two lead wires of the speaker respectively, and the DC resistance of the speaker's voice coil is measured at this time. This value of infinity indicates that the voice coil is open and the speaker cannot be used. If the measured resistance value is less than the nominal impedance value, it indicates that the mobile phone speaker is in good condition.

2. Put the multimeter in the RX1 gear and use a watch pen to connect with the speaker's finger and foot, and the other watch pen intermittently touches the other pin of the speaker, at this time, the speaker can make a clicking sound, and the pointer swings accordingly, indicating that the speaker is good. If there is no sound from the speaker and the multimeter pointer does not swing, it indicates that the speaker is faulty.

How the speaker works:

Magnetic speaker, also known as reed speaker, has a movable core of electromagnet between the two poles of the permanent magnet, when there is no current in the coil of the electromagnet, the movable core is attracted by the attraction of the two poles of the permanent magnet, and remains stationary in **, when there is a current flowing through the coil, the movable core is magnetized and becomes a magnet. With matching.

Electrostatic speaker is a speaker that works by using the electrostatic force added to the capacitor plate, and in terms of its structure, it is also called a capacitor speaker because the positive and negative electrodes are facing each other. There are two thick, hard plates that are fixed on the plates that allow sound to pass through, and a plate in the middle that uses a thin, light material as the diaphragm.

The method of self-repair if the speaker of the mobile phone is broken is as follows:

1. You may set the sound to be smaller, you can press the volume up button to adjust the sound louder.

2. Check whether the bell mouth of the mobile phone is blocked and remove the obscured object. For example, when holding the phone horizontally, your fingers block the bell at the bottom, and the unofficial standard protective case may also cause the bell mouth to be blocked.

3. If the pure socks are connected to the Bluetooth device, and the sound is emitted from the Bluetooth device, it is recommended to turn off the Bluetooth switch and check.

4. Change the sound source for observation.

5. The third-party application sets the audio system to the call state, if it is not restored, it will cause the audio channel to be confused, ** from the earpiece, the speaker has no sound, it is recommended to restart the phone to recover.

Introduction to mobile phones

Mobile phone, the full name of mobile ** or wireless**, commonly known as mobile phone, was originally just a communication tool, and in the early days, there was a common name of big brother, which is a portable ** terminal that can be used in a wide range, and was first developed from the battlefield mobile machine manufactured by Bell Labs in the United States in 1940. In 1958, the Soviet engineer Leonid. Kupriyanovich invented the -1 type move**.

In 1973, American Motorola engineer Martin Kudo Banda invented the world's first commercial mobile phone.

Mobile phone communication has gone through the 2G era and the 3G era, and has developed to the 4G era so far, and the 5G era is also closely followed, and 5G has been commercialized in China.

Summary. Hello, dear, poke the hole of the speaker with a needle, but this method may only puncture the metal mesh on the outside of the speaker, and it is difficult to cause substantial damage.

A small amount of water is dripped into the speaker opening until the speaker fails due to a short circuit, but this may cause damage to other components or even burn the motherboard.

Disassemble the phone,Disassemble it step by step to the speaker,Directly cut the cable or get the speaker down,But this is basically equivalent to ruining the phone itself。

How can I get my phone's speaker damaged.

Hello! I've seen you, please be patient for a few minutes For this question you asked, I've seen this question, don't worry, wait a minute, in the next 5 minutes, I will answer the question you asked, hello, dear, poke the hole of the speaker with a needle, but this method may only puncture the metal mesh outside the speaker, and it is difficult to cause substantial damage. A small amount of water is dripped into the speaker opening until the speaker fails due to a short circuit, but this may cause damage to other components or even burn the motherboard.

Disassemble the phone,Disassemble it step by step to the speaker,Directly cut the cable or get the speaker down,But this is basically equivalent to ruining the phone itself。

Dear, you can try these methods.

Summary. Hello dear.

It is not easy to break, and it is generally more durable, because the position of the mobile phone speaker is less likely to receive collisions in the mobile phone, and the other speaker itself is not a fragile product. So he is generally not easy to break, but if it is a violent fall, it may also cause his poor contact, which will affect the use of the speaker, in short, the speaker is still a more durable mobile phone component.

Is the phone horn easy to break.

It is generally more durable, because the position of the mobile phone speaker is less likely to receive collisions in the mobile phone, and the other speaker itself is not a fragile product. So he is generally not easy to break, but if it is a violent fall, it may also cause his poor contact, which will affect the use of the speaker, in short, the speaker is still a more durable mobile phone component.

Speakers with acceptable quality generally have a service life of more than 10 years. It won't break down after about three years of normal use. But this is theoretical data, if you turn on the loud sound every day to listen to ** or something, you will definitely not need it for three years.

There are also in addition to copycats and very poor quality mobile phones. The life of the speaker is greatly affected by the environment in which it is used, such as dust and iron-cut environments. There are two factors that affect whether the maximum volume is used for a long time, and other reasons are rarely damaged.
